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.
