Configuring APS/MSP
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.
Use the no version to restart a disabled interface.
See shutdown.
Use to enable SNMP link-status processing for the section and line layers of the
interface.
The default is enabled.
Example
host1(config-controll)#no snmp trap link-status
Use the no version to disable SNMP link status processing.
See snmp trap link-status.
Use to set the time that the router waits to set an alarm when the router records
a defect at the line or section layer.
Change this value from the default only when you are using MPLS fast reroute
over a SONET/SDH interface.
Specify a value of 0 milliseconds if the interface does not use APS/MSP or if
you want MPLS to have priority over APS/MSP.
Specify a value of at least 100 milliseconds if this interface uses APS/MSP
and if you want APS/MSP to have priority over MPLS.
Example
host1(config-controll)#trigger delay msec 1000
Use the no version to restore the default setting, 2500 milliseconds.
See trigger delay.
