Cisco ASR 9000 Series Command Reference Guide

•
The naming notation for T1 interfaces on a channelized SPA is
rack/slot/module/port/channel-num:channel-group-number, as shown in the following example:
interface serial 0/0/1/2/4:3
•
If a subinterface is configured under the serial interface, then the router includes the subinterface number
at the end of the serial interface address. In this case, the naming notation is
rack/slot/module/port[/channel-num:channel-group-number].subinterface, as shown in the following
example:
interface serial 0/0/1/2.1
•
The naming notation syntax for serial interfaces is as follows:
◦ rack—Chassis number of the rack.
◦ slot—Physical slot number of the modular services card or line card.
◦ module—Module number. Shared port adapters (SPAs) are referenced by their subslot number.
◦ port—Physical port number of the controller.
◦ channel-num:—T1 channel number. T1 channels range from 0 to 23.
◦ channel-group-number:—Time slot number. T1 time slots range from 1 to 24. The
channel-group-number is preceded by a colon and not a slash.
◦ subinterface—Subinterface number.

Use the question mark (?) online help function following the serial keyword to view a list of all valid
interface choices.
Serial interfaces on channelized T3 can be deleted using the no channel-group command in T1 configuration
mode. If there are nondefault serial parameters defined, you need to use the no interface serial command
first to revert to the default configuration, and then delete the serial interface using the no channel-group
command.

Examples
The following example shows how to enter interface configuration mode for a serial interface in slot 6, subslot
2, port 4, T1 channel number 10 and channel group 8:
RP/0/RSP0/CPU0:router(config)# interface serial 0/6/2/4/10:8
RP/0/RSP0/CPU0:router(config-if)#
The following example shows how to reference the serial interface on channel group 3 of T1 channel group
4 on port 2 of a SPA in subslot 1 and enter subinterface configuration mode:
RP/0/RSP0/CPU0:router(config)# interface serial 0/0/1/2/4:3
RP/0/RSP0/CPU0:router(config-if)#
