9.11Monitoring port traffic (port
mirroring)
In port mirroring, the valid data packets of one port, the source port, are cop-
ied to another, the destination port. The data traffic at the source port is not
influenced by port mirroring.
A management tool connected at the destination port, e.g. an RMON probe,
can thus monitor the data traffic of the source port.
The destination port forwards the data to be sent and blocks data received.
