Monitoring Port Traffic

will receive all the traffic (including MAC frames). If the monitored port is in FDX
mode, only half the traffic will be received on the analyzer port.

Note!

A special probe is needed for using the passive monitoring feature. Since

MAC frames are copied from the monitored port and since the analyzer port does
not itself run the MAC protocol, the probe must be able to attach to the switch
without trying to insert by means of the MAC protocol.
