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.
• When mirroring port traffic, the target port must be included in the
same VLAN as the source port.
• A source port can only mirror traffic to one target port.
Command Attributes
• Mirror Sessions – Displays a list of current mirror sessions.
• Source Unit – The unit whose traffic will be monitored.
• Source Port – The port whose traffic will be monitored.
• Type – Allows you to select which traffic to mirror to the target port,
Rx (receive), or Tx (transmit).
• Target Port – The port that will “duplicate” or “mirror” the traffic
on the source port.
