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 page 2-56.)
You can use the Mirror Port Configuration screen to designate a single
port pair for mirroring as shown below.
