For APS/MSP, you must configure a working interface and a corresponding protect
interface. You must also assign each pair of working and protect interfaces to a unique
group.
NOTE: Configuring the working interface before you configure the protect interface is
not required. You can configure the working interface before or after you configure the
protect interface.
The E120 and E320 routers does not support APS/MSP.
Configuring the Working Interface
To configure the working interface:
Select the interface.
1.
host1(config)#controller sonet 4/0
Specify the APS group to which the working and protect interfaces will belong.
2.
host1(config-controll)#aps group boston
Specify the interface as the working interface.
3.
host1(config-controll)#aps working
Use to specify the group to which the working and protect interfaces will belong.
Specify the name of the APS group.
Example
host1(config-controll)#aps group boston
Use the no version to remove a group of APS interfaces.
See aps group.
Use to specify the working interface.
Optionally, you can specify 1 as the channel number for the working interface. Because
the working interface is always assigned channel number 1, this is the only valid option.
Examples
host1(config-controll)#aps working
host1(config-controll)#aps working 1
Use the no version to prevent the interface from acting as a working interface.
See aps working.
