Is there a way to figure the total amount of traffic that is passing through a 6500? I have a switch that is serving as a collapsed backbone w/ about 35 VLAN's defined on it. I am preparing to install NAC but may have to install it in-band (gag) since we have a lot of old switches that are unsupported for out-of-band. I am trying to find out if the aggregate traffic for this switch exceeds the 1Gb connection that it will be restricted to if we go w/ the in-band solution.
Any help is greatly appreciated.
