[c-nsp] CSC CARD info

[Oliver Boehmer (oboehmer)]

Jack,

can you define "lots of ping drops"? primary CSC OIR (or CSC switchover)
is expected to cause traffic loss for a few seconds..
What type of fabric is this (2.5, 10 or 40Gbps) and which chassis? Do
you see the same traffic loss on all linecard types? If you see more
than 10 seconds or so loss, I would contact TAC..
