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 when using MSTP (see “Spanning Tree
Algorithm” on page 12-1).
Command Attributes
• Mirror Sessions – Displays a list of current mirror sessions.
• Source Port – The port whose traffic will be monitored. (Range: 1-18)
• 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 from the source
port. (Range: 1-18)
