Chapter 14 Configuring Automatic Protection Switching
Multirouter Automatic Protection Switching
Configuring MR-APS on Channelized Line Cards
To configure MR-APS on channelized line cards, enter the following commands beginning in global
configuration mode.
Step 9
Router(config-if)# aps protect circuit-number
ip-address
Configures an interface as a protect interface.
The ip-address argument specifies the IP address of the
router that has the working interface.
Step 10
Router(config-if)# exit
Exits interface configuration mode and returns to global
configuration mode.
Command Purpose
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 slot-one
mr-aps
Logically associates slots for APS processor redundancy.
To allow MR-APS to operate, you must associate a slot on
the working interface of one router and with a
corresponding protect interface on a second router.
Step 3
Router(config-r)# exit
Exits redundancy configuration mode and returns to global
configuration mode.
Step 4
Router(config)# controller SONET
slot#/subslot#/port#
Specifies the interface type and number. Enters controller
configuration mode.
Step 5
Router(config-controller)# aps group
group-number
Permits more than one APS protect and working interface
to be supported on a router.
Step 6
Router(config-controller)# aps working
circuit-number
Configures an interface as a working interface.
Step 7
Router(config-controller)# exit
Exits controller configuration mode and returns to global
configuration mode.
Step 8
Repeat steps 1 through 5 on the second router to configure the protect interface. Substitute the appropriate slot
numbers, interface types, and interface numbers. After you complete step 5, go to step 9.
Step 9
Router(config-controller)# aps protect
circuit-number ip-address
Configures an interface as a protect interface.
The ip-address argument specifies the IP address of the
router that has the working interface.
Step 10
Router(config-controller)# exit
Exits controller configuration mode and returns to global
configuration mode.
