2.5.2.2.Using a Mirror Port for Analysis
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. When mirroring port traffic,
note that the target port must be included in the same VLAN as the source port. (See
“Configuring Virtual LANs” on chapter 2.)
You can use the Port Mirror Configuration screen to mirror one or more ports to the
monitor port as shown below.
