Hi Ranganath,

Unfortunately, I have run those commands and no useful information can be gathered. However, the statistics are gathered from snmp operations. If this information is available via snmp, I believe that there is a command that could show the statistics of these stack ports.

C3750#show switch stack-ring activity
