[c-nsp] Unicast storms

[Brian Turnbow]

It would be all unicast traffic measured in 1 second intervals , not just unknown destinations, so you might want to try setting up a rate limit with permit actions to see if you are having bursts of traffic.

Well,

I have snmp, but this is not my understanding of unicast storm: as far as I
understand, unicast storm is defined as traffic with an unknown destination
MAC address.

I don't think you can see this with 'sh int' or SNMP, can you?
