Port Mirroring
Description
Port mirroring is a useful diagnostic tool because it allows you to send a
copy of the good Ethernet frames transmitted or received on one port to
another port. On the second port you can attach a protocol analyzer to
capture and analyze the data without interfering with the client on the
original port.
Source switch: Use the
z
to select the switch you want to
configure.
Source port: Use the
z
to select the port whose traffic you want
to mirror.
Target switch: Use the
z
to select the switch you want to receive
mirrored traffic.
Target port: Use the
z
to select a port to receive the mirrored
traffic. This is a port to which you have connected a protocol analyzer.
State: Use the
z
to enable or disable the port’s mirror.

CAUTION
Do not mirror traffic to a target
port that is connected to
network devices other than a
protocol analyzer. Their
behavior may be
unpredictable.
If a port is part of an
aggregated link, it cannot be
configured as the target port
for a port mirror. However, a
port in an aggregated link can
serve as the source port for a
port mirror.
