Chapter 14 Configuring Automatic Protection Switching Single-router Automatic Protection Switching Feature History for SR-APS Cisco IOS Release Description Required PRE 12.0(21)ST This feature was introduced on the Cisco 10000 series router. PRE1 12.2(13)BZ This feature was integrated into Cisco IOS Release 12.2(13)BZ PRE1 12.3(7)XI This feature was integrated into Cisco IOS Release 12.3(7)XI. PRE2 12.2(28)SB This feature was integrated into Cisco IOS Release 12.2(28)SB. PRE2 Configuring SR-APS To configure SR-APS, enter the following commands beginning in global configuration mode: Step 1 Command Router(config)# redundancy Step 2 Router(config-r)# associate slot odd-slot even-slot Step 3 Router(config-r)# exit Purpose Enters redundancy configuration mode, which allows you to associate two line cards as a redundant pair. Associates two line cards as a redundant pair. To allow SR-APS to operate, you must specify a line card installed in an odd slot number as the first member of a redundant pair; the second line card must be installed in the even-numbered slot to its right. Exits redundancy configuration mode and returns to global configuration mode. Note After you configure redundancy, the software treats the pair as though it occupies a single slot. The interface slot number is always the odd number of the redundant pair. For example, for the redundant pair occupying slots 5 and 6, the show interface pos 5/0/0 command refers to the active card (even if the active card occupies slot 6). Disabling SR-APS To disable SR-APS redundant operation, use the no form of the associate slot command. For example: Router(config-r)# no associate slot 3 4 If the redundant configuration is disabled, the software modifies the running configuration in the following ways: 1. The software removes all SR-APS configuration information. 2. The software creates two configurations, one for the primary card and one for the protect card. Table 14-1 shows examples of configuration files with redundancy enabled and disabled. OL-2226-23 Cisco 10000 Series Router Software Configuration Guide 14-29

Single-router Automatic Protection Switching
Feature History for SR-APS
Configuring SR-APS
To configure SR-APS, enter the following commands beginning in global configuration mode:
Note
After you configure redundancy, the software treats the pair as though it occupies a single slot. The
interface slot number is always the odd number of the redundant pair. For example, for the redundant
pair occupying slots 5 and 6, the
show interface pos 5/0/0
command refers to the active card (even if
the active card occupies slot 6).
Disabling SR-APS
To disable SR-APS redundant operation, use the
no
form of the
associate slot
command. For example:
Router(config-r)#
no associate slot 3 4
If the redundant configuration is disabled, the software modifies the running configuration in the
following ways:
1.
The software removes all SR-APS configuration information.
2.
The software creates two configurations, one for the primary card and one for the protect card.
Table 14-1
shows examples of configuration files with redundancy enabled and disabled.
Cisco IOS Release
Description
Required PRE
12.0(21)ST
This feature was introduced on the Cisco 10000 series router.
PRE1
12.2(13)BZ
This feature was integrated into Cisco IOS
Release 12.2(13)BZ
PRE1
12.3(7)XI
This feature was integrated into Cisco IOS Release 12.3(7)XI.
PRE2
12.2(28)SB
This feature was integrated into Cisco IOS
Release 12.2(28)SB.
PRE2
Command
Purpose
Step 1
Router(config)#
redundancy
Enters redundancy configuration mode, which allows you
to associate two line cards as a redundant pair.
Step 2
Router(config-r)#
associate slot
odd-
slot
even-slot
Associates two line cards as a redundant pair.
To allow SR-APS to operate, you must specify a line card
installed in an odd slot number as the first member of a
redundant pair; the second line card must be installed in the
even-numbered slot to its right.
Step 3
Router(config-r)#
exit
Exits redundancy configuration mode and returns to global
configuration mode.
