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 must share the same destination port.
• When mirroring port traffic, the target port must be included in the same VLAN as the
source port when using MSTP (see “Spanning Tree Algorithm Configuration” on page
3-156).
Command Attributes
• Mirror Sessions – Displays a list of current mirror sessions.
• Source Port – The port whose traffic will be monitored. (Range: 1-28)
• Type – Allows you to select which traffic to mirror to the target port, Rx (receive), Tx
(transmit), or Both. (Default: Rx)
• Target Port – The port that will mirror the traffic on the source port. (Range: 1-28)
Web – Click Port, Mirror Port Configuration. Specify the source port, the traffic type to be
mirrored, and the monitor port, then click Add.
