Configure Devices

This chapter provides the following topics:

Ways to Configure Devices Using Cisco Evolved Programmable Network Manager

Cisco EPN Manager provides two ways to change the physical devices in your network. The actions you can perform depend on your user account privileges and the types of devices in your network.

Launch Points for Configuring Devices

Use this method to:

Configuration menu from left-side navigation menu

Click on a Device Name, then click the Configuration tab.

You can configure device features on the selected device. You can also view the list of applied and scheduled feature templates that were deployed to the device.

Create and deploy configuration templates

Perform common network management tasks on one or more devices using system templates—for example, adding a hostname or configuring a routing protocol. You can also create your own templates to fit your deployment needs. Because they can be applied to multiple devices, templates normally apply to specific device operating systems or device types. When you use a configuration template, Cisco EPN Manager only displays devices that meet the template criteria.


Note

You can also edit device properties from the Network Devices table (Configuration > Network > Network Devices) by choosing a device and clicking Edit. This launches the device Edit Wizard. However, changes you make using the wizard are limited to device credentials, and any changes you make do not affect the physical device; they only update device information that is stored in the database.

For optical devices, you can also configure devices using Cisco Transport Controller, which you can launch from Cisco EPN Manager. See Launch Cisco Transport Controller to Manage Cisco NCS and Cisco ONS Devices

After you make your changes, save your changes to the database and optionally collect the device's physical and logical inventory. For more information, see Collect a Device's Inventory Now (Sync).

Which Devices Support the Configuration Operations?

Configuration operations are supported on a device if:

  • The device model is supported by Cisco EPN Manager.

  • The device operating system is supported by Cisco EPN Manager.

  • The applicable technology or service is supported by Cisco EPN Manager and is enabled on the device.

To find out what is supported, see Cisco Evolved Programmable Network Manager Supported Devices.

Identify the Commands Used In a CLI Configuration Template

Use this procedure to view the exact commands that are used by any of the commands you launch from the CLI Templates drawer.

Procedure

Step 1

Choose Configuration > Templates > Features and Technologies, then choose CLI Templates. For example:

  • Out-of-the-box templates are under System Templates - CLI.

  • Customized templates are under My Templates.

Step 2

Double-click the template in the left sidebar Templates menu.

Step 3

In the Template Detail area, choose the CLI Content tab. The commands are displayed in that tab.

Change a Device's Credentials and Protocol Settings

Use the following procedure to update device credentials and protocol settings. When you save the settings to the database, you can also perform an inventory collection to gather all physical and logical device changes and save those changes to the database, rather than wait for the daily inventory collection.

Procedure

Step 1

Choose Inventory > Network Devices.

Step 2

Select the device you want to edit, and click Edit. You can also choose several devices and make bulk changes.

Step 3

Double-click the parameters you want to change. Depending on the device type, you can edit:

  • Credential profile being used by device

  • Group the device belongs to

  • SNMP port, retries, timeout, credentials, and SNMPv3 authentication information

  • Telnet/SSH2 credentials and timeout

  • HTTP/HTTPS credentials, port, timeout

  • IPSec parameters

  • TL1 credentials and proxy IP address (for GNE/ENEs)

Step 4

Check that the new credentials are the same as those on the physical device by clicking Verify Credentials.

Step 5

Save your changes:

  • Update saves your changes in the database.

  • Update & Sync saves your changes to the database, but also collects device physical and logical inventory and saves all changes to the database.

Change Basic Device Properties

Cisco EPN Manager provides command templates that you can use to make basic property changes on your physical devices. To use these templates, choose Configuration > Templates > Features & Technologies, then choose CLI Templates > System Templates – CLI from the Templates pane on the left.


Note
The operations you perform here are different from those you perform with the Edit wizard (which you can launch from the Network Devices table). The Edit wizard changes the device property information that is saved in the database. It does not change properties on physical devices.

Enable and Disable Interfaces

Use the Interface 360 view to quickly enable and disable an interface. While you can perform these same actions from a Device Details page, using the Interface 360 view may be more efficient (for example, when responding to an alarm). The top right of the Interface 360 view provides an Actions menu that provides enable and disable options.

To launch an Interface 360 view, see Get a Quick Look at a Device Interface: Interface 360 View.

To enable and disable an interface from a device's Device Details page, see the interface configuration topics (Ethernet, Loopback, Serial, Tunnel, and so forth).

Configure Physical Attributes of Device Interfaces

Using Cisco EPN Manager, you can configure the physical attributes of your device's interfaces. Attributes such as card operating modes, bandwidth allocation per slot, slot pluggable types (such as VCoP), and AINS settings are configurable.

To configure the physical attributes of interfaces:

Procedure

Step 1

Choose Configuration > Network Devices.

Step 2

Select the device that you want to configure by clicking the device’s name hyperlink.

Step 3

Click the Configuration tab, then click the Logical View left side tab.

Step 4

To configure the interfaces, navigate to the paths described in the table below.

Step 5

To make your changes, click the controller/card name hyperlink and click the Edit icon at the top right corner of the page. Make your changes and click Save.

Table 1. Physical Attributes Configuration for Interfaces

Comments/Descriptions

Supported Slots/Controllers

Configure card type as 5G or 10G.

Physical > Card Mode

You can change the configuration from 10G to 5G but the other way around is not supported. Depending on the device you select, the default card mode is set to either 5G or 10G. For mode detailed information on the supported card modes, see Supported Devices for Cisco EPN Manager

Note 

You cannot configure the card modes on slots that are part of active circuits.

For more information about the device slots and supported card mode types, see table below (Device Slots and Supported Card Mode Types).

Configure card modes as T1 or E1.

Physical > Card Mode

You can change the configuration from T1 to E1 or vice versa depending on the device and card you select.

T1 and E1 modes represent the type of channelization mode used on the card.

Note 

You cannot configure the card modes on slots that are part of active circuits.

-

Configure card modes as OC3 or OC12.

Physical > Card Mode

You can set the card modes of A900-IMA4OS cards (of Cisco ASR 903 routers) as OC3 or OC12.

OC3 and OC12 modes represent the data transmission rates on the different optical transmission lines.

-

Configure Card Protection

Physical > Card Protection

Configure cards to act as primary or backup members (interfaces). A primary interface and its backup interface together make up a Protection Group (denoted by a unique integer). Associating cards with backup members ensures that when the primary interface fails, the protecting interface quickly assumes the traffic load from the primary interface. Cards displayed as the Active members are cards functioning as the protecting members of the service.

Ensure that the Primary and Backup members are of the same type. For example, if you choose a T1 interface as a Primary member, the Backup member must also be a T1 interface.

Hold-Off Timer is available for 1+1 card protection (NCS 42XX devices having IOS-XE version 16.10.1 or higher). It is used to prevent the successive switching in case of network inconsistency. The valid range is from 0 to 10 seconds. Default value is 5.

The Admin Mode for the protection group is configured in the order Lockout > Force Switch > Manual Switch > None. For more information about these modes and the revert timer, see the descriptions in Configure APS or MSP and UPSR or SNCP Protection Groups.

-

Configure NCS4200-1T16G-PS cards on NCS42xx devices.

Physical > Card Mode

You can view all the card modes of NCS4200-1T16G-PS cards, irrespective of the slot numbers.

Note 

Once you configure NCS4200-1T16G-PS card on some slots of NCS42xx devices, the configurations on those slots will be reset to the default values.

-

Configure A900-IMA8CT1Z-M and A900-IMA8CS1Z-M cards on ASR9xx devices.

Physical > Card Mode

You can view and configure the card modes of A900-IMA8CT1Z-M and A900-IMA8CS1Z-M cards.

-

Configure the interface module type for Automatic In-Service (AINS)

Physical > Automatic In-Service (AINS)

Use the Cards tab to configure the right controller types for AINS. In case of manual insertion and removal of cards, the AINS values are populated after a 20 min delay.

The ports/controllers tabs list all the AINS enabled ports and controllers. The supported ports and controllers are: Ethernet, E1, E3, T1, T3, and SONET and SDH. You can use the Edit icon to set the Secondary Admin State and Soak Timer (in hours or in minutes) values.

Note: Enabling AINS on a port/controller is an operation to be performed on the device manually.

Following are the Secondary Admin State values that you can set:

  • IS_AINS—indicates that the device is in Automatic In-Service state.

  • IS—indicates that the device is in in-service state.

  • OOS_MT—indicates that the device is in maintenance state.

Use the Soak Timer Hours field to set the soak timer in hours. The valid range is 0-48 hours. Use the Soak Timer Minutes drop-down list to set the soak timer in minutes. The available values are: 15, 30, and 45 minutes. The default value is 15 minutes.

-

Configure bandwidth that must be reserved for the selected device slots.

Physical > Bandwidth

The bandwidth you specify is reserved for the selected slot and made available to the slot irrespective of whether the slot is operational or not. In cases when the selected slot/card is down, and then back online after sometime, the configured bandwidth will be available for use based on the values specified in this field.

You can reserve a pre-configured bandwidth value of 80 or 100 Gbps on NCS4200-1T16G-PS cards on NCS42xx devices.

Configure the interface pluggable type for virtual Container over Packet (VCoP).

Physical > Pluggable Type

Use this menu to select the right port types for VCoP enabled interfaces. For example, the port types can be OC3, OC12, or DS3.

Note 

VCoP smart SFP provides an ability to forward the SONET signal transparently across the packet network. The VCoP smart SFP is a special type of optical transceiver which encapsulates SONET bit stream at STS1 or STS-3c or STS-12c level into packet format.

-

Conditions and Limitations: Following are the conditions and limitations for configuring controller modes on Cisco ASR 900 Series Route Switch Processor 2 (RSP2A) modules (A900-RSP2A-128) that are supported on Cisco ASR 920, Cisco NCS4202, and Cisco NCS 4206 devices:

  • The maximum bandwidth that can be configured is OC-48. A maximum of 20 ports on the module can be configured:

    • Ports 0-11 are T1 ports

    • Ports 12-15 are T3/E3 ports

    • Ports 16-19 are OC3/OC12 ports.

      Note 

      If a given port is configured as OC48, then only one of the given port can be configured since the maximum configurable bandwidth is OC48.

  • Configuration limitations on the Cisco A900-RSP2A-128 modules:

    • You cannot configure SDH/E3/E1/DS0 controller modes.

    • Configuring Ethernet as the controller mode is not supported.

    • The protection type UPSR cannot be configured.

    • Once you deploy the controller mode configuration to the device, you cannot undo the configuration using Cisco EPN Manager.

Configure Circuit Emulation

Cisco EPN Manager supports the provisioning of Circuit Emulation (CEM) which provides a bridge between traditional TDM network and packet switched network (PSN). CEM is a way to carry TDM (or PDH) circuits over packet switched network. Circuit Emulation (CEM) is the imitation of a physical connection. This feature allows you to use your existing IP network to provide leased-line emulation services or to carry data streams or protocols that do not meet the format requirements of other multiservice platform interfaces.

Cisco EPN Manager supports the following CEM modes:

  • Structure-Agnostic time-division multiplexing (TDM) over Packet (SAToP)—This is the unstructured mode in which the incoming TDM data is considered as an arbitrary bit stream. It disregards any structure that may be imposed on the bit stream. SAToP encapsulates the TDM bit streams as pseudowire (PWs) over PSN.

  • Circuit Emulation over Packet (CEP)—This mode is used to emulate Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) circuits and services over MPLS. To transport SONET/SDH circuits through a packet-oriented network, the Synchronous Payload Envelope (SPE) or Virtual Tributary ( VT) is broken into fragments. A CEP header and optionally an RTP header are prepended to each fragment.

For more information about CEM in Cisco EPN Manager, see, Supported Circuit Emulation Services.

When a line is channelized, it is logically divided into smaller bandwidth channels called higher-order paths (HOP) and lower-order paths (LOP). These paths carry the SONET payload. When a line is not channelized, the full bandwidth of the line is dedicated to a single channel that carries broadband services. Cisco EPN Manager enables you to channelize the T3 or E3 channels into T1s, and channelize the T1s further into DS0 time slots. Before you provision CEM services using Cisco EPN Manager, you must first configure the parameters for the HOP and LOP by configuring the interfaces for CEM.

A channelized SONET interface is a composite of STS streams, which are maintained as independent frames with unique payload pointers. The frames are multiplexed before transmission. SONET uses Synchronous Transport Signal (STS) framing while SDH uses Synchronous Transport Mode (STM) framing. An STS is the electrical equivalent to an optical carrier 1 (OC-1) and an STM-1 is the electrical equivalent to 3 optical carrier 1s (OC-1s).

This section describes how you can use Cisco EPN Manager to first configure your interfaces for CEM. You can then provision CEM services using these interfaces configured with appropriate controller modes and protection groups.

Pre-requisites for Configuring CEM Services

Before you provision a CEM service (see Provision Circuit Emulation Services), ensure that the following pre-requisites are met:

SONET Modes Configuration Examples

Configure APS or MSP and UPSR or SNCP Protection Groups

Viewing the protection groups for CEM helps you understand the enabled Automatic Protection Switching (APS), Unidirectional Path Switched Ring (UPSR), Multiplex Service Protection (MSP) and Subnetwork Connection Protection (SNCP) interfaces for your devices. APS and UPSR refers to the mechanism of using a protect interface in the SONET network as the backup for the working interface. Associating your interfaces with APS or UPSR protection groups, ensures that when the working interface fails, the protect interface quickly assumes its traffic load. The working interfaces and their protect interfaces together make up a Protection Group. SONET Protection Groups offer recovery from fiber (external) or equipment (interface and internal) failures at the SONET line layer. Using Cisco EPN Manager, you can view the working member for a SONET controller which acts as the main functioning controller for the CEM circuit. The Protecting Member acts as a backup for the main working controller. To view these details, ensure that the interfaces have been set with the required controller modes as explained in Configure Interfaces for CEM.

MSP and SNCP refer to the mechanism of using a protect interface in the SDH network as the backup for the working interface. Associating your interface with MSP or SNCP protection groups, ensures that when the working interface fails, the protect interface quickly assumes its traffic load. The working interfaces and their protect interface together make up a Protection Groups.

MSP is a protection mechanism in SDH for a port level protection, which provides 1+1 protection mechanism. In network topology map, all modes are supported including revertive, unidirectional, bidirectional, and acr/dcr modes. MSP in SDH is similar to APS in SONET. For example, in NCS 4206 device it has both working and protection modes.

SDH-MSP feature provides port level redundancy for SDH controller across Interface Module (IM). You can configure ports of different IM with one in working mode and the other port in protect mode.

SNCP is a protection mechanism for SDH networks that enables SDH connections to switch to another SDH circuit when a circuit failure occurs. A protection interface serves as the backup interface for the working interface. When the working interface fails the protection interface quickly assumes its traffic load. The switchover to a protection path occurs in the nonrevertive mode. If protection is switched to the protection path due to a transmission fault, there is no automatic switch-back to the original path once the fault is rectified. The functional equivalent of SNCP in SONET is called UPSR. You can provision CEM services and SNCP through Provision wizard or through CLI. The supported modes are VC4_16C, VC4_4C, VC4, AU4_VC12, AU4-VC11, AU3-VC12, AU3-VC11.

Note
Mix mode support is not available in Cisco EPN Manager 3.0.

Some Limitations are:

  • SDH supported modes with SNCP is not supported on STM64 port.

  • LOOPBACK and Bit Error Rate Testing (BERT) can be configured only on physical member controllers.

  • The supported scale is limited to 336 circuits

Before you modify the protection groups ensure to add controllers/interfaces to protection.

To configure APS/MSP protection groups and view UPSR/SNCP interfaces:

Procedure

Step 1

Choose Configuration > Network Devices.

Step 2

Select the device that is configured with protection groups, by clicking the device’s name hyperlink.

Step 3

Click the Configuration tab, then click the Logical View left side tab.

Step 4

Choose Circuit Emulation > Protection Group.

Step 5

To configure the APS/MSP parameters, click the APS/MSP tab, click the Protection Group hyperlink of the group that you want to modify, and click the Edit icon at the top right corner of the page.

Step 6

You can view and configure the following fields.

  • The Working Member represents the SONET/SDH controller which acts as the main functioning controller for the circuit.

  • The Protecting Member represents the SONET /SDH controller which acts as the backup to the working member for the circuit.

  • The Protection Status indicates whether the group is an active or inactive member for the circuit.

  • The Hello Time and Hold Time fields represent the time range for the protecting and working members. The hello timer defines the time between hello packets. The hold timer sets the time before the protect interface process declares a working interface's router to be down. By default, the hold time is greater than or equal to three times the hello time.

  • The Loopback IP determines the configuration for the protect interface which includes the IP address of the router (normally its loopback address) that has the working interface.

  • The Revertive Time , in minutes, enables automatic switchover from the protect interface to the working interface based on the configured time after the working interface becomes available. If revertive time is zero then the protection is non-revertive.

  • The Directional drop-down menu represents the direction in which the backup protection must be enabled.

    • In the bidirectional mode, a failure on a working member triggers an APS/MSP switchover of the working member to the Protecting member. Here the receive and transmit channels are switched as a pair.

    • In the unidirectional mode, failure on a working member triggers an APS/MSP switchover of only the failed member to the corresponding line of the Protection interface.

  • The ADM checkbox, if enabled, associates Add Drop Multiplexors (ADMs) with the protecting member.

  • The APS Request drop-down menu enables you to configure the following values. The values can be configured in the order Lockout > Force Switch > Manual Switch > No Mode. For example, if Force Switch is currently configured on the device, then you can configure only Manual Switch or No Mode values. You cannot configure Lockout when Force Switch is configured.

    • Lockout: Prevents a working interface from switching to a protect interface. For example, if the protect interface is configured as circuit 1, the Lockout option prevents the protect interface from becoming active.

    • Manual Switch: Manually switches a circuit to a protect interface, unless a request of equal or higher priority is in effect.

    • Force Switch: Manually switches a circuit to a protect interface, unless a request of equal or higher priority is in effect. For example, if the protect interface is configured as a particular circuit, the force command sets the protect interface to active.

    • No Mode: Removes the current APS/MSP request configuration from the protection group on the device.

Note 
To clear the protection group of SONET or SDH , choose either SONET or SDH protection group ID and then click the delete (X icon).
Step 7

To view similar parameters associated with UPSR/SNCP interfaces, click the UPSR/SNCP tab.

Configure Clocking for CEM

Clocking modes define multiple ways to achieve the same clock in the transmitting and receiving ends of a CEM circuit. Cisco EPN Manager enables you to configure clock recovery and distribution in these ways:

  • Synchronous Clocking — with synchronous clocking, PDH (TDM) lines on the source and destination are synchronized to the same clock delivered by some means of physical clock distribution (SONET, SDH, and so on). The clock on the particular TDM line can be delivered from

    • Line: the transmit clock is from the receiver of the same physical line.

    • Internal: the controller will clock its sent data using the internal clock.

    • Free Running: the transmit clock is taken from line card and can be derived from an internal free running oscillator.

    • Recovered: the transmit clock is derived from an in-band pseudowire-based activeclock recovery on a CEM interface.

    To set these clocking values in Cisco EPN Manager, see Configure CEM Interfaces.

  • Adaptive Clocking — adaptive clocking is used when the routers do not have a common clock source. The clock is derived based on packet arrival rates based on dejitter buffer fill level. You can set the size of the Dejitter Buffer (in the range of 1-32) during provisioning of CEM services in Cisco EPN Manager. The size of the Dejitter Buffer determines the ability of the circuit to tolerate network jitter.

  • Differential clocking — differential clocking is used when the cell site and aggregation routers have a common clock source but the TDM lines are clocked by a different source. The TDM clocks are derived from differential information in the RTP header of the packet with respect to the common clock. Differential clock recovery is based on time stamps received in the RTP header.

To configure clock recovery for CEM:

Procedure

Step 1

Click the Configuration tab, then click the Logical View left side tab.

Step 2

Choose Clock > Recovered Clock.

Step 3

To add a new interface from which the clock source must be derived, click the Add (‘+’) icon.

Step 4

To edit the existing recovered clock configuration, click the Recovering Interface hyperlink and click the ‘Edit’ icon at the top right of the page.

Step 5

Specify the following recovered clock values:

  1. Enter a unique numerical value for the Recovered Clock ID for easy identification of the recovered clock configuration. This ID can then be used to associate the CEM interfaces directly with this the recovered clock configuration.

  2. From the Recover Mode drop-down list choose:

    • Adaptive— when devices do not have a common clock source, the recovered clock is derived from packet arrival rate on the controller selected as the Protecting Member for the associated Protection Group.

    • Differential— when the edge devices have a common clock source, the recovered clock is derived from timing information in packets and the related difference from the common clock.

  3. Enter a unique numerical value for easy identification of the CEM Group Number. This identifies the CEM group associated with the clock.

  4. Choose the required controller from the Recovering Interface drop-down list. This controller associated with the clock is the virtual CEM interface from which the clock is derived when a backup clock source is required.

Configure Modes of SDH in EPNM

A Synchronous Transport Module (STM) signal is the Synchronous Digital Hierarchy (SDH) equivalent of the SONET STS. In this document, STM term refers to both path widths and optical line rates. The paths within an STM signals are called administrative units (AUs). An AU is the information structure that provides adaptation between the higher-order path layer and the multiplex section layer. It consists of an information payload (the higher-order VC) and an AU pointer, which indicates the offset of the payload frame start relative to the multiplex section frame start. The AU-3 pointer is composed of 3 bytes; the AU-4 pointer is composed of 9 bytes. The payload of the STM-1 frame consists of one AU-4 unit or three AU-3 units. Augment Mapping An administrative unit group (AUG) consists of one or more administrative units occupying fixed, defined positions in an STM payload. Augment mapping is supported at STM1 level.

The following types of augment mapping are supported:.

  • Augment Mapping AU-4


    Note
    This is the default augment mapping mode

Synchronize the Clock Using Sync-E, BITS, and PTP

Synchronous Ethernet (Sync-E):

Using Cisco EPN Manager, you can enable frequency synchronization to provide high-quality bit clocks synchronization over Ethernet interfaces. Synchronous Ethernet (Sync-E) provides this required synchronization at the physical level.

To do this you need to configure Sync-E that helps routers identify the clock in the network with the highest priority. This clock is also called the Primary Clock. All the other devices (members) on the network reset their clocks based on the primary clock’s settings. Messages are constantly exchanged between the primary clock and its members to ensure efficient continued synchronization of all clocks in the network. Cisco EPN Manager enables you to specify this primary clock and also set the Sync-E parameters at the global and interface levels. Once the Sync-E properties have been configured, you can view the logical hierarchy and topology between the devices on the network topology overlay.

Note
Sync-E configuration is supported only on Ethernet interfaces.

Building Integrated Timing Supply (BITS):

BITS is the method by which clocking information is provided by a Building Integrated Timing Supply (BITS) port clock. In Sync-E, Ethernet links are synchronized by timing their bit clocks from high-quality, stratum-1-traceable clock signals in the same manner as SONET/SDH. Operations messages like SSM and ESMC maintain Sync-E links and ensure that a node always derives its timing from the most reliable source.

Precision Time Protocol (PTP):

In networks that employ TDM, periodic synchronization of device clocks is required to ensure that the receiving device knows which channel is the right channel for accurate reassembly of the data stream. The Precision Time Protocol (PTP) standard:

  • Specifies a clock synchronization protocol that enables this synchronization.

  • Applies to distributed systems that consist of one or more nodes communicating over a network.

PTP uses the concept of primary and subordinate devices to achieve precise clock synchronization. With the help of Cisco EPN Manager, you can use PTP to configure the primary device which periodically starts a message exchange with the subordinate devices. After noting the times at which the messages are sent and received, each subordinate device calculates the difference between its system time and the system time of the primary device. The subordinate device then adjusts its clock so that it is synchronized with the primary device. When the primary device initiates the next message exchange, the subordinate device again calculates the difference and adjusts its clock. This repetitive synchronization ensures that device clocks are coordinated and that data stream reassembly is accurate. The PTP clock port commands are used to modify PTP on individual interfaces. Once the PTP properties have been configured, you can view the logical hierarchy and topology between the devices on the network topology overlay.


Note

Due to the limitations on the device, you can configure a maximum of 4 clock sources on interface modules, with a maximum of 2 per interface module. This limitation applies to both Sync-E and TDM interfaces.

Configure IP SLAs (TWAMP Responder)

The IETF Two-Way Active Measurement Protocol (TWAMP) defines a standard for measuring round-trip IP performance between any two devices that support the TWAMP protocols. The TWAMP-Control protocol is used to set up performance measurement sessions. It is used to send and receive performance-measurement probes. TWAMP enables complete IP performance measurement and provides a flexible choice of solutions as it supports all devices deployed in a network.

When you configure TWAMP using Cisco EPN Manager, the device you select is configured as a TWAMP server and you enter the TWAMP server configuration mode. It then uses the port value that you specify to configure the port to be used by the TWAMP server that listens for connection and control requests. The Inactivity Value that you specify will be configured as the inactivity timer (in seconds) for a TWAMP control session.


Note

When you configure IP SLA using Cisco EPN Manager, the IP SLA responder is automatically configured on the device. You do not have to use the command ip sla responder twamp to pre-configure the IP SLA responder.

To configure interfaces for TWAMP:

Before you begin

A TWAMP control-client and the session-sender must be pre-configured in your network before you can configure TWAMP responder using Cisco EPN Manager.

Provision Optical Interfaces

You can use Cisco EPN Manager to enable the following configuration options on your optical devices.


Note

The following configuration options are enabled or disabled depending on the device you select. To check whether your device supports these options, see Supported Devices for Cisco EPN Manager.

  • Ethernet MTU

    Using Cisco EPN Manager you can configure the MTU values on the Ethernet interfaces of your optical devices. The MTU is the Maximum Transmission Size, in bytes, of a packet passing through the interface. You can use Cisco EPN Manager to modify the MTU values on all Ethernet interfaces except Gigabit Ethernet and Fast Ethernet interfaces on TNC and ECU modules.

    To verify that your new Ethernet MTU values are configured on the device, navigate to your device’s Device Details page and click the Ethernet Interface tab.

  • GMPLS

    Using Generalized Multi-Protocol Label Switching (GMPLS), you can define and view the fiber and alien wavelength parameters that are used during GMPLS circuit creation. It ranges the packet based data on the MPLS protocol to allow the creation and maintenance of channels across the networks. It supports non-packet switching devices. This means that GMPLS extends the packet based MPLS protocol to allow creation and maintenance of tunnels across networks that consist of non-packet switching devices. GMPLS tunnels can traverse Time-Division Multiplex (TDM) interfaces and switching types.

    To configure GMPLS, you can use the Configuration tab in Cisco EPN Manager which allows you to configure GMPLS on all LMP enabled optical controllers. The enabling of LMP which is a pre-requisite for GMPLS configuration can also be done using the same Configuration tab.


    Note

    You cannot disable GMPLs on LMP enabled controllers that are part of active optical circuits.

  • Packet Termination

    Using Cisco EPN Manager you can set up packet termination on the ODU controllers of your optical devices. To do this, ensure that packet termination is pre-configured on the device for Ethernet packets. You can then edit the configuration that is already created on the device and discovered by Cisco EPN Manager.

    To configure packet termination, you must specify both the Termination Mode and Mapping Mode values.

  • LMP

    The Link Management Protocol (LMP) helps in managing channels and links that are required between nodes for routing, signaling, and link management. LMP is also used to manage the Traffic Engineering (TE) link. It allows multiple data links into a single Traffic Engineering (TE) link that runs between a pair of nodes.

    To create an LMP neighbor using Cisco EPN Manager, you need to specify the neighbor’s name, link ID, router ID, and interface ID, and the common link and interface IDs. You can add only one LMP link per controller on your optical device.

    While the LMP configuration can be successfully deployed to a single device using Cisco EPN Manager, for LMP to function effectively, you need to configure it on both sets of devices that are participating in the link. This ensures that the LMP link is activated.

    Limitations:

    • You cannot edit the Numbering value of an LMP link after it has been created. To edit the Numbering value, delete the LMP link and recreate it with the new Numbering value.

    • You cannot have duplicate Neighbor Router IDs between two LMP neighbors.

    • When you add an LMP link, ensure that the controller is not already associated with another LMP link. This will cause your deploy to fail.

  • OTN Topology

    You can use the Configuration tab to add or modify the topology instance and Area ID associated with an optical OTN controller. If the controller does not have a pre-configured Topology Instance and Area ID, Cisco EPN Manager automatically sets the topology instance to OTN and the Area ID to 0.

    Cisco EPN Manager does not allow you to use the same topology instance and Area ID that is already pre-configured on other controllers. To know the Topology Instance and Area ID that is pre-configured on the device, go to Maps > Network Topology.

  • NNI

    You can configure your optical interfaces to act as network-node interfaces (NNIs). An NNI indicates that the interface connects to other network nodes. Cisco EPN Manager allows you to configure NNIs on the OTU controllers of your optical device. These interfaces can further be configured to act as source and destination ports.

    If a device is not part of a topology, configuring its NNI controller creates an OTN topology instance for that controller with an Area ID 0.

    You can create only one NNI configuration per controller for every controller present on the device.

    Note: You cannot delete NNI controllers that are pre-configured with a Topology Instance.

  • Breakout

    Enabling breakout on your optical devices utilizes the multilane architecture of the optics and cables to enable you to split single higher density ports into multiple lower density ports. For example, a 100G port can be configured to operate as ten different 10G ports. Or a single 40G port can act as four different 10G ports. To configure breakout using Cisco EPN Manager, see the table below.

    Pre-requisite:

    Ensure that Breakout is pre-configured on the interface by changing the interface’s Port Mode value to Breakout. See Change the Payload and Breakout Settings. This changes all other port mode parameters of that interface to ‘None’ enabling breakout on the port, thus allowing you to configure lanes. You can add up to ten lanes per interface.

    Limitations:

    • All lanes that belong to a particular interface must have the same mapping type.

    • OTU2 and OTU2e controllers are supported only if they are in the packet termination mode.

    • In Cisco NCS 5.2.4x devices, breakout lanes can only be created when the port modes are of type Ethernet.

    • 10G clients that are mapped to OPU2e framing type are not supported.

    • Breakout cannot be configured on SONET and SDH controllers.

    Example configuration:

    If you select a controller optics 0/0/0/0 and enable Breakout with GFPF as its mapping mode and with a framing value of OPU2, then the configuration pushed to the device is: 

    controller optics 0/0/0/0 breakout-mode 1 ethernet framing opu2 mapping gFpF
  • Performance Monitoring

    Performance Monitoring (PM) helps you gather performance counters for system maintenance and troubleshooting. You can retrieve both current and historical PM counters at regular intervals. You can enable and disable performance monitoring on OTU and ODU controllers of an optical device.

    To configure performance monitoring at the TCM controller level, you must configure OTN interfaces and their associated TCM performance counters, see:

  • Channelize ODU (LO) Controllers:

    Associate your ODU controllers with multiple lower order ODU sub-controllers and configure tributary port number (TPN) and tributary slots (TS) for those ODU sub-controllers. A valid range of TPN is from 1 to 80. If a TS string is separated using a colon (:), this indicates individual tributary slot. If a TS string is separated using an en-dash (-), this indicates a range of tributary slots.

    When you select the ODU level for the sub-controllers, ensure that the sub-controller's ODU level is lower than that of the main controller you are associating it with. For example, if you are associating sub-controllers with an ODU controller of ODU3 level, then the sub-controllers cab be of levels ODU2, ODU1, or ODU1.

  • Configuring OTDR Settings:

    Using this feature, you can configure OTDR scans to begin automatically on a fiber span that has been repaired or on the startup of an OSC channel. To do this, ensure that the 'Auto Scan on LOS' parameter is enabled. A fiber is considered to be repaired when the LOS on the fiber is cleared and an alarm is raised based on the following criteria:

    • If you check the Enable Absolute Threshold checkbox, the 'OTDR-LOSS-THR-EXCEEDED' alarm is raised when the insertion loss measured for the OTDR scan is greater than the Absolute Event Loss Threshold (dB) value configured.

    • If the total back reflection for the OTDR scan is less than the Total Back Reflection (dB) value that you specify.

    • If the Absolute Pass Fail Criteria is disabled, the Loss and Back Reflection values from the baseline scan in the previous release are considered as threshold values. In this scenario, the OTDR-LOSS-THR-EXCEEDED alarm is raised.

    Depending on how you want the auto scans to be triggered, you can configure the following parameters:

    • Auto Scan on Span Loss Increase- OTDR scan starts automatically on the fiber if the measured span loss on the fiber is greater than the threshold value configured. The default threshold value is 2.

    • Enable OLR continuous measurement on Rx direction- measures the span loss in the LINE-RX port (input) of the card depending on the configured threshold value.

    • Enable WDM Side from WSON Provisioning- prevents creation of circuits when the Loss and Back reflection threshold values are crossed during an OTDR scan.

    You can configure the Event Loss Threshold value within which the total span loss on the fiber is permitted. If the measured span loss on the fiber is greater than the Event Loss Threshold value, then the OTDR scan is triggered on the fiber.

  • Configure Automatic Laser Shutdown (ALS):

    Automatic Laser Shutdown (ALS) is a technique used to automatically shut down the output power of the transmitter in case of issues such as a fiber break. This is a safety feature that prevents dangerous levers of laser light from leaking out of a broken fiber, provided ALS is provisioned on both ends of the fiber pair. Once an interface has been shut down, you can configure the action the action that must be taken to restart the interface by setting the ALS mode to:

    • Disabled mode—If mode is disabled, ALS is disabled. Loss Of Signal (LOS) will not cause laser shutdown.

    • Manual restart mode—The laser is turned off when the ALS agent detects an LOS for 500 ms. After ALS is engaged, a manual command is issued that turns on the laser for the time period of the pulse width. The laser is turned on when the LOS has been cleared for 100 ms.

    • Automatic restart mode—The laser is shut down for the time period of pulse spacing when the ALS agent detects a LOS for 500 ms. Then, the laser automatically turns on for the time period of the selected pulse width. If an LOS still exists at that time, the laser is shut down again. This pattern continues until the LOS is cleared for 100 ms; then, the laser will stay on.

    Cisco EPN Manager enables you to set the ALS mode, the ALS recovery interval (in seconds), and the recovery pulse width (in seconds). If the ALS Mode for the interface has been set to Manual Restart, you need to manually restart the interface. To do this, navigate to the device's Device Details page, choose Optical > Automatic Laser Shutdown, locate the interface set to the Manual Restart ALS mode, and click the Restart button.

  • Using the SNTP Server to Set the Date and Time:

    Simple Network Time Protocol (SNTP) is an internet protocol used to synchronize the clocks of computers to a time reference. Using the SNTP server ensures that all NEs use the same date and time reference. The server synchronizes the node’s time after power outages or software upgrades.

    To use the SNTP server to set the date and time you must first specify the current time along with the time zone value and then set the primary and backup servers that can be used as a point of reference for the date and time. Before you set the timezone values, ensure that the SNTP server values are not configured. When you delete an SNTP server, ensure that you first delete the Backup server and only then the Primary server. You cannot delete only the Primary server.

  • Configuring the Wavelength:

    Cisco EPN Manager enables you to provision the wavelength frequency for your optics controllers. You can view the current wavelengths configured on the optics controllers and then depending on the type of card selected, you can change the wavelength frequency.

    You can configure the wavelengths on an optics controller only when it is configured as a DWDM optics port. The optics port must not be in the In Service state when you are changing the wavelength.

Change the Admin Status of an Optical Interface
Cisco EPN Manager enables you to change the admin state of an interface to enhance the performance testing abilities for your optical network. The Admin Status of an interface defines whether the interface is being managed by Cisco EPN Manager, whether it is down, or whether it is in maintenance mode. When the admin status of an interface is down, it indicates that the interface is in an unreachable state, or that the device is not supported by Cisco EPN Manager. Changing the admin status to Up enables Cisco EPN Manager to manage the interface and thus provide better monitoring capabilities. To change the admin state on an interface:
Procedure
Step 1

Choose Configuration > Network Devices.

Step 2

Click the device hyperlink to launch its Device Details page.

Step 3

Click the Configuration tab.

For Cisco NCS 2000 and Cisco ONS devices, this choice is under the Logical View tab that is at the top of the Device Details page.
Step 4

Choose Optical Interfaces > Provisioning > Admin Status.

The interfaces of the selected device are displayed along with their Admin State settings. Interfaces on which you cannot modify the admin state, for example, PCHAN and PLINE interfaces are not displayed.
Step 5

Click either the Optical Controllers or Ethernet Controllers tab to edit the required controllers.

Step 6

To edit the admin status, select the interface by clicking the interface's Name hyperlink, and then click the Edit icon at the top right corner of the page. Ensure that the device's inventory collection status is in Managed or Completed state.

Choose one of the following values:

  1. Down—implies that the interface will be administratively down.

  2. Up—implies that the interface will be administratively up.

  3. Testing— implies that the interface is in Maintenance state and that the administrator is performing tests using it.

Step 7

Click Save to save to deploy your changes to the device.

A pop-up notification notifies you about the status of your changes. To see an example of the admin status being changed on a Cisco NCS2K device, see Example: Change the Admin Status for Cisco NCS 2006 Interface.

Note 

If the Edit task fails, check if the device is in Managed or Completed state and ensure that Cisco EPN Manager is in sync with the device configuration. If not, re-sync the device with Cisco EPN Manager as described in Collect a Device's Inventory Now (Sync).

Configure Protection Profiles

Using Cisco EPN Manager, you can provision different protection profiles (or groups) for your optical devices. This ensures availability and improved reliability for these devices. Protection profiles define whether Automatic Protection Switching (APS) must be enabled on the cards and they also set the direction for traffic flow in case of failures. The cards on the device can either be set to support unidirectional regeneration of configuration or can be set to ensure that both transmit and receive channels will switch when a failure occurs on one.

Procedure
Step 1

Choose Configuration > Network Devices.

Step 2

Click the device hyperlink to launch its Device Details page.

Step 3

Click the Configuration tab.

For Cisco NCS 2000 and Cisco ONS devices, this choice is under the Logical View tab that is at the top of the Device Details page.
Step 4

Choose Optical Interfaces > Provisioning > Protection Profile.

Step 5

To add a protection profile, click the + symbol.

Step 6

Provide a unique name for the protection profile. The name is a mandatory field and should not contain space or exceed 32 characters.

Step 7

Select the required type for the protection profile. Your options are:

  • One plus one BDIR APS- Enables one plus one Automatic Protection Switching (APS) and configures the card to be bidirectional.

  • One plus one UNIDIR APS- Enables one plus one APS and configures the card to be unidirectional.

  • One plus one UNIDIR NO APS- Enables one plus one with no APS and configures the card to be unidirectional.

  • One plus one PLUS R BIDIR APS - Enables one plus one plus R APS and configures the card to be bidirectional.

Note 

  • BDIR (bidirectional) indicates that both transmit and the receive channels will switch if a failure occurs on one.

  • UNIDIR (unidirectional) indicates that the card supports unidirectional regeneration of configuration. Hence the ports can only be used as the link source if they are transmit ports and as the link destination if they are receive ports.

Step 8

Select the protection mode for the profile as Revertive or Non-Revertive. Revertive mode ensures that the node returns traffic towards the working port post a failure condition after the amount of time specified as the Wait to Restore Time (step 9).

Step 9

Select the sub network connection mode as SNC_N (default), SNC_I, or SNC_S.

Step 10

When you select the sub network connection mode as SNC_S, you can then select TCM-ID value from the TCM drop-down list. By default, TCM-4 is selected once you select SNC_S as Sub Network Connection mode. You can change the TCM-ID column value from TCM4 to TCM1-TCM6 for SNC_S.

Note 
For SNC_I and SNC_N, you are not allowed to change the TCM-ID value. It should be set to None.
Step 11

Enter a value for the Wait to Restore Time in seconds using a number between 0 and 720. For any value greater than 0, ensure that the value is greater than 300 and in intervals of 30 seconds. The wait to restore time defines the time the system must wait to restore a circuit. If you have selected the protection mode as Revertive, then the default wait to restore time is 300, else it is 0.

Step 12

Enter a value for the Hold Off Time in milliseconds. This value defines the time the system waits before switching to the alternate path. The valid range is from 100 to 10000 seconds. Default value is 0.

Step 13

Click Save to deploy the updated changes to your device.

Step 14

(Optional) To verify, view the updated protection profile parameters in the Configuration tab for the selected controller, under Optical Interfaces > Provisioning > Protection Profile.

Configure TCM and TTI Parameters

Using Cisco EPN Manager you can configure Tandem Connection Monitoring (TCM) and Trail Trace Identifiers (TTI) on ODU controllers of ODU Tunnel circuits. This helps you enable and disable performance monitoring capabilities on these controllers.

You can further monitor your device’s capabilities by configuring the threshold for signal failure and signal degrading in the TCM connections of these ODU controllers. You can also modify the source and destination access point identifiers. To do this, ensure that the following pre-requisites are met.
Before you begin

  • Ensure that the device’s inventory collection status is ‘Completed’.

  • Ensure that the controllers are configured for Loopback. If not, change the controllers loopback settings under Optical Interfaces > Maintenance > Loopback. See Configure Loopback Interfaces.

Configure Patchcords for a Device

The client card trunk ports and the DWDM filter ports can be located in different nodes or in the same single-shelf or multi-shelf node. A virtual link is required between the client card trunk ports and the DWDM filter ports. The internal patchcords provide virtual links between the two sides of a DWDM shelf, either in single-shelf or multishelf node. The patchcords are bidirectional, however, each direction is managed as a separate patchcord.

This feature is only supported on Cisco NCS 2000 and  Cisco ONS devices.

This procedure explains how to configure internal patchcords using the Chassis View using ANS (automatic node setup) for WDMs (wavelength division multiplexing). You can use the Chassis View to create and delete these internal patchcords. To configure origination (TX) and termination (RX) patchcords for a device:

Procedure

Step 1

From the left sidebar, choose Configuration > Network Devices.

Step 2

Select the device that you want to configure by clicking the device's name hyperlink. The Chassis View tab for the device appears.

Step 3

In the right pane, click the Configuration sub-tab, and then expand the Internal.patchcord area.

Step 4

Click the + icon, and then choose the required origination (TX) and termination (RX) patchcords for the device.

Step 5

Click Finish. The patchcords are added to the Internal Patchcords table.


Note

Once you have created the patchcord, you cannot modify it. However, you can delete it.

You can select a patchcord or multiple patchcords in the Internal Patchcords table to view the direction of the patchcords in the Chassis View of the device, which is displayed in the left pane (as shown in the figure below).

Configure a Protection Group for a Shelf in a Device

Use this procedure to create a protection group for a shelf in a device.


Note

You cannot configure a protection group for a rack.

Before you begin

Following are the prerequisites before creating a protection group for a shelf:

  • To create a Y Cable protection group, ensure that two cards of the same type that are configured with client ports are plugged in to the same shelf.

  • To create a Splitter protection group, ensure that at least one OTU2XP card that is configured with trunk port 3-1 and trunk 4-1, is plugged in to the shelf.

Procedure

Step 1

From the left sidebar, choose Configuration > Network Devices.

Step 2

Select the device that you want to configure by clicking the device's name hyperlink. The Chassis View tab for the device appears.

Step 3

Expand the Chassis View Explorer, and then select the shelf for which you want to configure the protection group.

Step 4

In the right pane, click the Configuration sub-tab, and then expand the Protection area.

Step 5

Click the + icon to open the Create Protection Group window.

Step 6

From the Type drop-down list, choose one of the following protection type:

  • Splitter—This protection type is applicable only when a MXPP/TXPP card is used. These cards provides splitter (line-level) protection (trunk protection typically on TXPP or MXPP transponder cards).

  • Y Cable—This protection type is applicable only when two transponder or two muxponder cards that are configured with client ports, are plugged in to the same shelf in a device.

Step 7

Choose a protect port and a working port for the shelf.

Note 

You will be able to select these ports only if you have completed the prerequisites listed at the beginning of this procedure.

Step 8

Choose if the protection type is uni-directional or bi-directional. In the bidirectional mode, a failure on a active interface triggers a switchover of the traffic from the active interface to the protecting/backup interface.

Step 9

Click the Revertive toggle radio button to revert the shelf from the protected port to the original port after the failure is fixed.

Step 10

Choose the hold off time in mili seconds. Hold off time is the period that the shelf on the protected port must wait before switching to the original port after the failure is fixed. The shelf can revert to the original port after the hold time expires. The minimum value of hold off time must be 0.5.

Step 11

Click Apply. The protection group is added to the Protection table.

    • If you set the Loopback parameter to Internal, Cisco EPN Manager applies the same configuration applied for a terminal loopback.

Configure Controllers (Optics, OTS, OCH, DSP, and DWDM)

Using Cisco EPN Manager, you can configure optical device controller parameters such as the wavelength, FEC, SD and SF BER reporting and thresholds, and more for controllers of type OTS, OTS OCH, DWDM, and more.

The Optical Transport Section (OTS) controller holds all the optical parameters for the OTS optical interfaces. The optical interface has different capabilities depending on its hardware components such as VOA and amplifier. Hence, the parameters enabled or disabled on the OTS controller depend on the actual hardware capability on the specific optical interface. You can configure parameters such as amplifier gain range, amplifier tilt, and OSRI for the OTS controller.

The Optical Transport Section OCH (OTS OCH) controller represents the OCM device available on the OTS optical interface. This controller has channel granularity over the OTS interface. The OTS OCH controller contains the wavelength information. You can configure only the admin status for the OTS OCH controller.

To ensure that you complete the slice configuration before configuring the controllers, see, Configure Slices for NCS 1002 Devices.

Configure GMPLS and WSON Properties

GMPLS UNIs:

The Generalized Multiprotocol Label Switching (GMPLS) User Network Interface (UNI) creates a circuit connection between two clients (UNI-C) of an optical network. This connection is achieved by signaling exchanges between UNI Client (UNI-C) and UNI Network (UNI-N) nodes, where UNI-C nodes are router nodes and UNI-N nodes are optical nodes.

GMPLS UNI is supported only on the 100G and 200G trunk ports of the Cisco NCS 1002 node. The prerequisite for the OCH trail circuit is to create a Link Management Protocol (LMP) link between the optical channel Add/Drop NCS 2000 series interface on the NCS 2000 series node and the NCS 1002 interface on the NCS 1002 node.

UNI is divided into client (UNI-C) and network (UNI-N) roles. A UNI-C network element requests and accepts circuit provisioning information. A UNI-N network element is the node adjacent to the UNI-C node and accepts and transports circuit provisioning information across the core network.

For UNI circuit provisioning, the network must meet the following requirements:

  • An NE must be configured in as UNI-C and connected to a UNI-N NE.

  • An NE must be configured as UNI-N and connected to a UNI-C NE.

Static UNIs:

Link Management Protocol (LMP) is a logical link that is created on the trunk optics controller on the source and destination nodes of the tunnel. You can create static LMP links (Static UNIs) between the ports of two different devices. For example between a Cisco NCS 2000 series node and a Cisco NCS 1002 node. This then helps configure an LMP neighbor for a GMPLS UNI tunnel.

While configuring a Static UNI using Cisco EPN Manager, the RX Port and TX Port that you choose identify the card, shelf, or slot that you want participating in the UNI. While the RX Port represents the source for the UNI, the TX Port represents the destination.

Use the Remote Device field to specify the management IP address of the selected node. Use the Remote Client Interface field to choose the LMP link IP address of the optics controller.

Alien Wavelength:

Use the Alien Wavelength tab to view and configure the port and wavelength parameters for the alien wavelength. You can also specify the required alien wavelength type, trunk mode and the forward error correction (FEC) mode.

Fiber Attributes:

You can configure the parameters used during creation of the GMPLS UNI by configuring values such as the fiber type (by choosing Dispersion-Shifted (DS), True-Wave Classic (TWC), or other values). You can also specify the fiber length and specify the Polarization Mode Dispersion fiber coefficient.

The Attenuator In value identifies the input optical attenuation in dB between the node output port (for example, a LINE-TX port) and the input parameter of the fiber. Similarly, the Attenuator Out value identifies the same between the node input port (for example, a LINE-RX port) and the output parameter of the fiber.

You can choose the Channel Spacing value that configures the minimum frequency spacing between two adjacent channels in the optical grid. To specify the maximum number of channels expected on the span use the Channel Number field. Ensure that the channel number and channel spacing values are consistent. For example, there cannot be 80 channels with 100 GHz spacing.

Virtual Trunk:

You can use the Virtual Trunk tab to specify the Drop Ports, Description Configuration, and Alien Wavelength Type for the device.

LMP Termination:

You can use the LMP Termination tab to specify the Virtual Trunk, LMP Type, Remote Device, Remote Interface, and Peering for a device. You can also edit the existing LMP Terminations in the LMP Termination tab.

To configure GMPLS/WSON parameters:

Procedure

Step 1

  • The Remote Client Interface field specifies the link IP address of the controller.

Note 

You can configure a remote TXP node using the above settings.
Create and edit GMPLS UNIs GMPLS/WSON sub-tab > GMPLS UNIs

  • Specify the ingress and egress ports for the GMPLS UNI and choose if the UNI is of type numbered or unnumbered. Ensure that you specify if the UNI is of type UNI-C or UNI-N.

  • The trunk values are automatically configured to the respective alien wavelength values depending on your GMPLS UNI configuration. If the configured alien wavelength is supported on both trunk ports, then setting it on one of the trunk ports automatically configures the same alien wavelength on both trunk ports.

  • For Cisco NCS 2000 devices, the GMPLS UNI trunk value can be set to Default.

  • Specify the local and remote interface IP, and remote system IP and controller. These values enable the remote system connection for the UNI.

    Note 

    You can only specify remote system IPs of devices that are managed by Cisco EPN Manager.
