Cisco IOS Interface and Hardware Component Command Reference

service-module t1 linecode

To select the line code for the fractional T1/T1 module, use the service-modulet1linecode command in interface configuration mode. To select the default, the B8ZS line code, use theno form of this command.

service-module t1 linecode {ami | b8zs}

no service-module t1 linecode {ami | b8zs}

Syntax Description


ami	Specifies alternate mark inversion (AMI) as the line code.
b8zs	Specifies binary 8 zero substitution (B8ZS) as the line code. This is the default.

Command Default

The default line code is B8ZS.

Command Modes

Interface configuration

Command History


Release	Modification
11.2	This command was introduced.
12.2(33)SRA	This command was integrated into Cisco IOS Release 12.2(33)SRA.
12.2SX	This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.

Usage Guidelines

Configuring B8ZS is a method of ensuring the ones density requirement on a T1 line by substituting intentional bipolar violations in bit positions four and seven for a sequence of eight zero bits. When the CSU/DSU is configured for AMI, you must guarantee the ones density requirement in your router configuration using the service-modulet1data-codinginverted command or the service-modulet1timeslotsspeed56 command.

Your T1 service provider determines which line code, either ami or b8zs , is required for your T1 circuit.

Examples

The following example specifies AMI as the line code:


Router(config)# interface serial 0
Router(config
-if)
# service-module t1 linecode ami

Related Commands


Command	Description
service-module t1 data-coding	Guarantees the ones density requirement on an AMI line using the fractional T1/T1 module.
service-module t1 timeslots	Defines time slots that constitute a fractional T1/T1 (FT1/T1) channel.

service-module t1 remote-alarm-enable

To generate remote alarms (yellow alarms) at the local CSU/DSU or detect remote alarms sent from the remote CSU/DSU, use the service-modulet1remote-alarm-enable command in interface configuration mode. To disable remote alarms, use theno form of this command.

service-module t1 remote-alarm-enable

no service-module t1 remote-alarm-enable

Syntax Description

This command has no arguments or keywords.

Command Default

Remote alarms are disabled.

Command Modes

Interface configuration

Command History


Release	Modification
11.2	This command was introduced.
12.2(33)SRA	This command was integrated into Cisco IOS Release 12.2(33)SRA.
12.2SX	This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.

Usage Guidelines

Remote alarms are transmitted by the CSU/DSU when it detects an alarm condition, such as a red alarm (loss of frame) or blue alarm (unframed ones). The receiving CSU/DSU then knows that there is an error condition on the line.

With D4 Super Frame configured, a remote alarm condition is transmitted by setting the bit 2 of each time slot to zero. For received user data that has the bit 2 of each time slot set to zero, the CSU/DSU interprets the data as a remote alarm and interrupts data transmission, which explains why remote alarms are disabled by default. With Extended Super Frame configured, the remote alarm condition is signalled out of band in the facilities data link.

You can see if the FT1/T1 CSU/DSU is receiving a remote alarm (yellow alarm) by issuing the showservice-moduleserial command.

Examples

The following example enables remote alarm generation and detection:


Router(config)# interface serial 0
Router(config
-if)
# service-module t1 remote-alarm-enable

Related Commands


Command	Description
service-module t1 framing	Selects the frame type for a line using the fractional T1/T1 (FT1/T1) module.
show service-module serial	Displays performance statistics for an integrated CSU/DSU.

service-module t1 remote-loopback

To specify that the fractional T1/T1 DSU/CSU module enters loopback mode when it receives a loopback code on the line, use the service-modulet1remote-loopback command in interface configuration mode. To disable remote loopbacks, use the no form of this command.

service-module t1 remote-loopback {full | payload v54}

no service-module t1 remote-loopback {full | payload v54}

Syntax Description


full	Configures the remote loopback code used to transmit or accept CSU loopback requests.
payload	Configures the loopback code used by the local CSU/DSU to generate or detect payload-loopback commands.
v54	Industry standard loopback code. Use this keyword for CSU/DSUs that may not support the Accunet loopup standards. This keyword is used only with a payload request, not a full request.

Use the full keyword to enable the standard loopup codes, which use a 1-in-5 pattern for loopup and a 1-in-3 pattern for loopdown. Use the payload v54 keywords to enable the v54 pseudo-random loopup codes for loopup and v54 pseudo-random loopdown codes for loopdown.

Command Default

Full and payload loopbacks with standard loopup codes

Command Modes

Interface configuration

Command History


Release	Modification
11.2	This command was introduced.
12.3(2)T	The provision for an alternate loopback code was removed.
12.2(33)SRA	This command was integrated into Cisco IOS Release 12.2(33)SRA.
12.2SX	This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.

Usage Guidelines

The no form of this command disables loopback requests. For example, the noservice-modulet1remote-loopback full command ignores all full-bandwidth loopback transmissions and requests.

Configuring the no form of the command might not prevent telco line providers from looping your router in extended super frame (esf) mode because fractional T1/T1 lines use facilities data link messages to initiate loopbacks.

To have the loopback remote commands on the FT1/T1 CSU/DSU module function successfully, you need to enable the service-modulet1remote-loopback command.

Note

Use the full keyword to enable the standard loopup codes, which use a 1-in-5 pattern for loopup and a 1-in-3 pattern for loopdown. Use the payload v54 keywords to enable the v54 pseudorandom codes for loopup and v54 pseudorandom codes for loopdown.

Examples

The following example shows how to configure two routers connected back-to-back through a fractional T1/T1 line to enter loopback mode:


Router(config)# interface serial 0/0
Router(config-if)# service-module t1 remote-loopback full
 
Router(config-if)# loopback remote full
!
%SERVICE_MODULE-5-LOOPUPREMOTE: Unit Serial0/0 - Remote unit placed in loopback
Router(config-if)# no loopback remote
%SERVICE_MODULE-5-LOOPDOWNREMOTE: Unit Serial0/0 - Remote loopback test cancelled
The following example shows how to configure two routers connected back-to-back through a fractional T1/T1 line to enter loopback mode and generate or detect payload-loopback commands:
Router(config-if)# service-module t1 remote-loopback payload v54
 
Router(config-if)# loopback remote payload
%%SERVICE_MODULE-5-LOOPUPREMOTE: Unit Serial0/0 - Remote unit placed in loopback

Related Commands


Command	Description
loopback remote (interface)	Loops packets through a DSU/CSU to a remote DSU/CSU and back over a channelized T1 link.

service-module t1 timeslots

To define time slots that constitute a fractional T1/T1 (FT1/T1) channel , use the service-modulet1timeslots command in interface configuration mode. To resume the default setting (all FT1/T1 time slots transmit at 64 kbps), use the no form of this command.

service-module t1 timeslots {range | all} [speed {56 | 64}]

no service-module t1 timeslots {range | all}

Syntax Description


`range`	The DS0 time slots that constitute the FT1/T1 channel. The range is from 1 to 24, where the first time slot is numbered 1 and the last time slot is numbered 24. Specify this field by using a series of subranges separated by commas.
all	Selects all FT1/T1 time slots.
speed	(Optional) Specifies the time slot speed.
56	(Optional) 56 kbps.
64	(Optional) 64 kbps. This is the default.

Command Default

64 kbps is the default for all time slots.

Command Modes

Interface configuration

Command History


Release	Modification
11.2	This command was introduced.
12.2SX	This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.

Usage Guidelines

This command specifies which time slots are used in fractional T1 operation and determines the amount of bandwidth available to the router in each FT1/T1 channel.

The time-slot range must match the time slots assigned to the channel group. Your service provider defines the time slots that comprise a channel group.

To use the entire T1 line, enable the service-modulet1timeslots all command.

Examples

The following example displays a series of time-slot ranges and a speed of 64 kbps:


Router(config
-if)
# service-module t1 timeslots 1-10,15-20,22 speed 64

service-module wlan-ap interface number bootimage [autonomous | unified]

Syntax Description


`interface` `number`	The interface number for the wireless device. Always use 0.
autonomous	Autonomous software image.
unified	Upgrade image with Lightweight Access Point Protocol (LWAPP).

Command Default

Autonomous software image

Command Modes

Privileged EXEC

Command History


Release	Modification
12.4(20) T	This command was introduced for wireless-enabled Cisco 880 Series and Cisco 890 Series Integrated Services Routers.

Usage Guidelines

When running the advanced IP services feature set on either Cisco 880 Series routers or Cisco 890 Series routers, use the service-module wlan-ap 0 bootimage unified command to enable the Cisco unified software upgrade image on the embedded wireless access point. After enabling the unified image, use the service-module wlan-ap 0 reload command to perform a graceful shutdown and reboot of the access point.

Note

The service-module wlan-ap 0 bootimage command does not support recovery images on the embedded access point. Use the service-module wlan-ap 0 reload command to shutdown and reboot the access point.

Cisco 880 Series and Cisco 890 Series routers with embedded access point running the unified software image require DHCP to obtain an IP address for the access point. An IP address is needed to communicate with the Wireless LAN Controller (WLC) and to download its image upon boot up. The host router can provide DHCP server functionality through the DHCP pool to reach the WLC, and setup option 43 for the controller IP address in the DHCP pool configuration.

Use the following guideline to setup a DHCP pool on the host router.


ip dhcp pool embedded-ap-pool
    network 60.0.0.0 255.255.255.0
    default router 60.0.0.1
    option 43 hex f104.0a0a.0a0f  /* Single WLC IP address (10.10.10.15) in HEX format */
int vlan 1  /* Default Vlan */
ip address 60.0.0.1 255.255.255.0
int Wlan-GigabitEthernet0 /* internal switch-port to AP */
switchport access vlan 1

Examples

The following example upgrades the embedded access point image from autonomous to unified.

0	Sets the DF bit to 0 (clears the DF bit ) and allows packet fragmentation.
1	Sets the DF bit to 1 which prohibits packet fragmentation.

Command Default

The DF bit value is not changed in the IP header.

Command Modes

Route-map configuration

Command History


Release	Modification
12.1(6)	This command was introduced.
12.2(33)SRA	This command was integrated into Cisco IOS Release 12.2(33)SRA.
12.2SX	This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.

Usage Guidelines

Using Path MTU Discovery (PMTUD) you can determine an MTU value for IP packets that avoids fragmentation. If ICMP messages are blocked by a router, the path MTU is broken and packets with the DF bit set are discarded. Use the setipdf command to clear the DF bit and allow the packet to be fragmented and sent. Fragmentation can slow the speed of packet forwarding on the network but access lists can be used to limit the number of packets on which the DF bit will be cleared.

Note

Some IP transmitters (notably some versions of Linux) may set the identification field in the IP header (IPid) to zero when the DF bit is set. If the router should clear the DF bit on such a packet and if that packet should subsequently be fragmented, then the IP receiver will probably be unable to correctly reassemble the original IP packet.

Examples

The following example shows how to clear the DF bit to allow fragmentation. In this example a router is blocking ICMP messages and breaking the path MTU. Using policy routing both the inbound and outbound packets on interface serial 0 will have their DF bit set to 0 which allows fragmentation.


interface serial 0
ip policy route-map clear-df-bit
route-map clear-df-bit permit 10
match ip address 111
set ip df 0
access-list 111 permit tcp any any

12.2SX	This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.

Usage Guidelines

The shelf number is used to distinguish between cards on the router shelf and cards on the dial shelf.

Caution

You must reload the Cisco AS5800 for the shelf number to take effect. The shelf numbers are part of the interface names. When you reload the Cisco AS5800, all NVRAM interface configuration information is lost.

You can specify the shelf number through the setup facility during initial configuration of the Cisco AS5800. This is the recommended method to specify shelf numbers.

To display the shelf numbers, use the showrunning-config command. If a shelf number has been changed, the pending change is shown in the output of the showversion command (for example, the dial-shelf ID is 87; will change to 2 on reload).

Examples

In the following example, the dial shelf is assigned the number 456:


Router(config)# shelf-id 456 dial-shelf
Router(config)# exit

Usage Guidelines

This command displays the types and status of cards installed in a Cisco 7304 router (such as network services engines [NSEs], RPs, line cards, MSCs, and SPAs), and information about incompatible FPGA images. When the bundled and current FPGA images are compatible, they are not displayed.

This command also displays whether your system is in compliance with line card configuration guidelines. For NSEs and line cards, empty slots are not displayed in the output. However, for SPAs, several status values are reported, including an empty subslot, which is reported as “missing.”

If your system contains an unsupported line card or RP with no matching bundled FPGA image in Cisco IOS software, then this command displays “None” instead of the bundled FPGA version number.

Use this command to display information about the status of the active and standby NSEs.

Examples

The following example displays information about a Cisco 7304 router that has current FPGA images:

Command History


Release	Modification
12.2(14)SX	Support for this command was introduced on the Supervisor Engine 720.
12.2(17d)SXB	Support for this command on the Supervisor Engine 2 was extended to Release 12.2(17d)SXB.
12.2(33)SRA	This command was integrated into Cisco IOS Release 12.2(33)SRA.
12.2(33)SXI	The output of the show catalyst6000 traffic-meter command was changed to include traffic monitor status information.

Usage Guidelines

If you enter the switching-clock keywords, the output displays whether switching of the redundant clock sources on the backplane is allowed if the active clock source fails.

There are either 64 or 1024 MAC addresses that are available to support the software features. You can enter the show catalyst6000 chassis-mac-address command to display the MAC-address range on your chassis.

In Cisco IOS Release 12.2(33)SXI and later releases, the traffic monitor status information is displayed in the output. In earlier releases, only the current and peak traffic-meter readings are displayed.

Examples

This example shows how to display the MAC-address ranges and the current and peak traffic-meter readings:


Router> 
show catalyst6000 all
chassis MAC addresses: 64 addresses from 0001.6441.60c0 to 0001.6441.60ff
  traffic meter =   0%  Never cleared
           peak =   0%  reached at 08:14:38 UTC Wed Mar 19 2003
  switching-clock: clock switchover and system reset is allowed

12.2(2)XB1	This command was introduced on the Cisco AS5850 universal gateway.
12.2(11)T	This command was integrated into Cisco IOS Release 12.2(11)T.
15.0(1)M	This command was modified in a release earlier than Cisco IOS Release 15.0(1)M. The detail keyword was added. The clocks and split keywords were removed.

Usage Guidelines

You must enter this command from one of the route-switch-controller (RSC) cards.

Use the showchassis command to display additional output relevant to handover-split mode. Command output shows the RSC card to be configured with all slots of the entire chassis, regardless of configured ownership. Slots owned by the peer RSC are shown in the ignore state, properly configured and ready to go.

Examples

The following example shows output for a system in handover-split mode. Each RSC is shown to be configured with all slots in the entire chassis, regardless of whether the RSC actually owns the slot. Slots that are not owned by an RSC are shown to be in the ignore state. The RSC from which the command is entered owns slots 0 to 5, but has configured for it all slots (0 to 5 and 8 to 13--all slots except those in which the RSCs are inserted). Entries for slots 8 and 10 show the designator “ignore.”
