PORT CONFIGURATION

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.

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.

•The switch can only mirror one port at a time.

Command Attributes

•Mirror Sessions – Displays a list of current mirror sessions.

•Source Port – The port whose traffic will be monitored.

•Type – Allows you to select which traffic to mirror to the target port, Rx (receive), Tx (transmit), or Both.

•Target Port – The port that will “duplicate” or “mirror” the traffic on the source port.
