OIR'ing the primary CSC (slot 17 by default) will _always_ result in traffic loss because the CSC clocks and schedules all fabric traffic.

Remember to shutdown the primary CSC using hw-module shut command, wait at least 1 min before OIR'ing and failing over from primary to secondary CSC.

Hi all,

what is significance of slot no of CSC.

If we use 2 CSC and 3 SFC

When I do OIR of slot 17 CSC ( when MASTER ) we get 3 ping drops for transit
traffic through the router.
When I do OIR of slot 16 CSC ( when MASTER ) we get lot of ping drops for
transit traffic through the router and neighbourships break.
