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.
Command Attributes
• Mirror Sessions – Displays a list of current mirror sessions.
• Source Port – The port whose traffic will be monitored. (Range: 1-26)
• Type – Allows you to select which traffic to mirror to the target port, Rx (receive),
or Tx (transmit). (Default: Rx)
• Target Port – The port that will mirror the traffic on the source port.
(Range: 1-26)
