Configuring the Switch
2-33Using 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 network sniffer 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 configured in the same VLAN as the
source port (see “Configuring Virtual LANs” on page 2-44).
You can use the Mirror Port Configuration screen to designate a single port pair for
mirroring as shown below:
