PW redundancy — VLL resilience for a switched PW path

Note:

The 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C can only be configured as a T-PE node and not as an S-PE node.

VC-switching is not supported on the 7210 SAS-Dxp, 7210 SAS-K 2F1C2T, 7210 SAS-K 2F6C4T, and 7210 SAS-K 3SFP+ 8C.

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

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