USING THE SYSTEM CONFIGURATION PROGRAM

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 2-53.)

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