Icon and State Reference

Device Reachability and Admin States

Device Reachability State—Indicates whether Cisco EPN Manager can communicate with the device using all configured protocols.

Table 1. Device Reachability State

Icon

Device Reachability State

Description

Troubleshooting

Reachable

Cisco EPN Manager can reach the device using SNMP, or the NCS 2K device using ICMP.

—

Ping reachable

Cisco EPN Manager can reach the device using Ping, but not via SNMP.

Although ICMP ping is successful, check for all possible reasons why SNMP communication is failing. Check that device SNMP credentials are the same in both the device and in Cisco EPN Manager, whether SNMP is enabled on the device, or whether the transport network is dropping SNMP packets due to reasons such as mis-configuration, etc. See Change Basic Device Properties.

Unreachable

Cisco EPN Manager cannot reach the device using Ping.

Verify that the physical device is operational and connected to the network.

Unknown

Cisco EPN Manager cannot connect to the device.

Check the device.

Device Admin State—Indicates the configured state of the device (for example, if an administrator has manually shut down a device, as opposed to a device being down because it is not reachable by Ping).

Description

Troubleshooting

Managed

Cisco EPN Manager is actively monitoring the device.

Not Applicable.

Maintenance

Cisco EPN Manager is checking the device for reachability but is not processing traps, syslogs, or TL1 messages.

To move a device back to Managed state, see Move a Device To and From Maintenance State.

Unmanaged

Cisco EPN Manager is not monitoring the device.

In the Network Devices table, locate the device and click the "i" icon next to the data in the Last Inventory Collection Status column. The popup window will provide details and troubleshooting tips. Typical reasons for collection problems are:

  • Device SNMP credentials are incorrect.
  • The Cisco EPN Manager deployment has exceeded the number of devices allowed by its license.
  • A device is enabled for switch path tracing only.

If a device type is not supported, its Device Type will be Unknown. You can check if support for that device type is available from Cisco.com by choosing Administration > Licenses and Software Updates > Software Update and then clicking Check for Updates.

Unknown

Cisco EPN Manager cannot connect to the device.

Check the device.

Device Sync State

Device Sync State—Indicates status of the Sync operation performed on a device.

Port or Interface States

Port or Interface Primary States—Conveys the most important state information for a port or interface by combining the admin and operational states. The Multilayer Trace displays either a port's primary state or alarm status. For the Chassis View, if an element does not support the changing of color to indicate a state change, you can still get the state change information from the alarm that is generated.


Note

If there is an alarm associated with a port/interface, alarm icon will show up, port icon will not show. The alarm is shown only in case the port is not in test or admin down state.

Circuit or VC Serviceability State— This value is a combination of the circuit or VC's admin and operational states. The admin state is shown because it impacts service operability. For optical circuits, the admin state also determines whether the Activate and Deactivate actions are available. The operational state is shown to quickly identify whether a service is working or not.

Circuit or VC Serviceability State

Icon

Description

Admin Down

Circuit or VC manually shut down by the administrator.

Down

Circuit or VC is operationally down and administratively up.

Up

Circuit or VC is operationally and administratively up.

Auto Up

Circuit or VC is operationally auto up and administratively up. Only certain devices support the Auto Up operational state.

Unavailable

Circuit or VC has not been discovered yet, or its operational status is unavailable.

Partial

Circuit/VC operational or administrative state is partial.

  • Partial admin state—The circuit or VC has a mixed administrative request (to activate some service resources and deactivate others), has a mix of resources that are administratively up and down, or has resources whose operational state is unavailable.

  • Partial operational state—The circuit or VC has a mix of some active and deactivated resources, or the operational state for some of its resources are unavailable.

Up - Unprotected

The circuit/VC that was configured with a protection path is operational but cannot switch to the alternate path because of severe failures.

Note 

This serviceability status indication is supported for OCHCC WSON circuits with Y-Cable protection and protected ODU.
