Configuring Port Mirroring

You can mirror traffic from any source port to a target port for real-time analysis. You can then attach a logic analyzer or RMON probe to the target port and study the traffic crossing the source port in a completely unobtrusive manner.

Source port(s)

Single target port

Command Usage

•Monitor port speed should match or exceed source port speed, otherwise traffic may be dropped from the monitor port.

•All mirror sessions have to share the same destination port.

•When mirroring port traffic, the target port must be included in the same VLAN as the source port.
