We use catalyst 6500's and 3500's. I am taking over control of this network and want to know if there are users that should be moved to a different vlans. I am mainly concerned with broadcast domains and overall bandwidth.
Todd, you may also try PRTG traffic grapher,
they provide up to three free sensors in
their software whereby you can monitor real time traffic on a physical interface. For more than three interfaces then you have to purchase software.
