Operation Diagnostics
9.9 Monitoring port traffic
(port mirroring)
In port mirroring, the data traffic related to a port, the source port, is copied
to another port, the destination port. Data traffic at the source port is not in-
fluenced by port mirroring.
A management tool connected to the destination port, such as an RMON
probe, can thus observe the data traffic at the source port.
The destination port forwards data to be sent and blocks received data.
