Description (partial)

The switch not being accessible over IP. Ping to switch fails.

The vlan and/or stp table gets corrupted in hardware. As a result packets destined for the switch do not get sent to CPU as the vlan/stp mapping is incorrect. Hence switch reachability is impacted.
Mostly seen when there is high amount of ipv6 traffic which is generally seen when CDB is deployed in daisy-chain or ring topology.
