VLL resilience for a switched PW path

Note:

The 7210 SAS platforms as described in this document can be configured as S-PE nodes.

The following figure shows a VLL resilience for a switched pseudowire path example. A sample configuration follows.

Example: T-PE1 configuration

configure service epipe 1
endpoint X
exit
endpoint Y
revert-time 100
standby-signaling-master
exit
sap 1/1/1:100 endpoint X
spoke-sdp 1:100 endpoint Y 
precedence primary
spoke-sdp 2:200 endpoint Y 
precedence 1
spoke-sdp 3:300 endpoint Y 
precedence 1

Example: T-PE2 configuration

configure service epipe 1
endpoint X
exit
endpoint Y
revert-time 100
standby-signaling-slave
exit
sap 2/2/2:200 endpoint X
spoke-sdp 4:400 endpoint Y 
precedence primary
spoke-sdp 5:500 endpoint Y 
precedence 1
spoke-sdp 6:600 endpoint Y 
precedence 1

Example: S-PE1 configuration

VC switching indicates a VC cross-connect so that the service manager does not signal the VC label mapping immediately but put this into passive mode.

configure service epipe 1 vc-switching 
spoke-sdp 1:100 
spoke-sdp 4:400
