Etherchannel - Individual Link Utilization

I am looking into the utilization of individual links within a 4 port etherchannel group that is used as a trunk on a Cat 5500. I want to understand the output of the command "show channel traffic". In looking at the output I see a percentage of traffic for each link for Unicast, Multicast and Broadcast packets. My questions are these:

1. Is percentage based upon number of packets or octet throughput?

2. Why are Rx-Bcst and Tx-Bcst percentages always at 0% on all of my switches?

3. Are there any other relevant commands to monitor the utilization of individual links in a etherchannel group?

Thanks,

Chris Stierle

Re: Etherchannel - Individual Link Utilization

The docs are not specific on how these calculations are made. You might learn something talking to a Cisco tac engineer.
