Description (partial)


The ip address configuration might be lost after a LC reload.


When we have a bad MSC in the system whose one EIO link (out of 2 links) is bad, among other problems, one of the visible impact is delay in applying the config.

The MSC can be checked for bad EIO links using the following command.

RP/0/RP1/CPU0:CRS-P1#show controllers pse eio links all location 0/2/CPU0
Tue Jun 23 07:58:39.223 PST

             Node: 0/2/CPU0:
