Using a Port Mirror 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 configured in the same VLAN and be operating at the same
duplex mode as the source port (see VLAN Static List on page 33).
You can use the port mirror configuration screen to designate a single port
pair for mirroring as shown below:
