Munir,

The "show port PORT_NUMBER statistics" command will give you a count of tx/rx broadcast packets.


Switch.4 # show port 1-8 statistics

Munir,

That looks absolutely beautiful. The switch output in that screenshot shows very little actual packets going to the CPU.

Hi Munir,

I don't quite understand your question. The 'show l2stat' command shows how many packets have gone to the CPU since the last time the 'clear counters' command was run or the switch was rebooted. Earlier in the thread, Chad Smith mentioned that anything over 500-1000 PPS going to the CPU from an edge port is worthy of being investigated. Can you explain your question in more detail?
