6-6 Mirroring
The switch supports port mirroring. A copy of the egress (transmit) data and the ingress
(receive) data of the mirrored (monitored) port is sent to the mirroring (snooping) port. A
user can attach a monitoring device to the mirroring port, such as a sniffer or an RMON
probe to view the traffic at the mirrored port. This is useful for network monitoring and
troubleshooting.
The switch allows for only one mirrored port at any given time. Port mirroring is
independent from L2 switching. The receive mirrored port still forwards the frame to the
mirroring port, even if the frame is eventually dropped.
To configuring port mirroring, click on the M
IRROR
folder in the left-hand side bar. The
