I would like to know the command for checking the BW utilization of a DS3 link which is terminating on a Catalyst switch port. For this link we have configured the IP and others in MSFC through a VLAN inteface. But sh int vlan "#" is not giving the accurate utilization. I tried sh port , sh counters, sh mac etc.. all these commands in Cat. But still i am not getting the accurate utilization output like " last 5 min input rate #### " on a native OS.
