Hi all,
I have a question regarding port-channel load balancing in IOS. How can I see the load balancing statistics for an etherchannel? I was once shown a command where I could see tx rx bit counters rising and confirming traffic was going over all interfaces bundled, not over just one. I have issued the command: port-channel load-balance src-dst-ip, and understand that this mode will utilize all interfaces. Thanks in advance.

Hi,
utilizing all interfaces really depends on your traffic flows so no load balancing can assure you utilize all links.
Wouldn't the show etherchannel load-balance give the desired output? You could implement a MQC config to match for any traffic on each interface and see the counters.

What's the hardware/software of the device where you want to see the stats?
I remember using the following command on 6500 switch to see what port in the etherchannel will be used for a specific source-destination pair.
test etherchannel load-balance interface port-channel number {ip | mac}
[source_ip_add | source_mac_add] [dest_ip_add | dest_mac_add].
This command works on 3750 as well.
