Operation diagnosis
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 source port's data traffic in sending and receiving direc-
tion.
The destination port forwards the data to be sent and blocks data received.
