I need to be able to use CV (with CW for Windows) to monitor some 3550 switches in read-only mode. Right now I am using a read community string, and can only view overall switch status and some switch and port level graphs. I really need to be able to see how the ports are configured, (VLAN assignment, duplexing, etc.) but don't want to be able (and won't be allowed) to alter anything. How can my Ops people set this up?
