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.
