I am looking at the web interface for the 3750 and noticed that the Port Utilization frame doesn't show any activity at all (for both individual ports or a summary of them). Am I missing something? Do I have to enable a feature? Thanks for the help.
I suppose you are using CiscoView Device Manager (CVDM). CVDM is only for 6000 series swicthes. For 3750 switches, we must use Cisco Network Assistant (CNA).
