Using a Port Mirror for Analysis
You can mirror traffic from any source port to a target port for real-time
analysis. You cana 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, not that the target
port must be included in the same VLAN as the source port.
You can use the Mirror Port Configuration screen to designate a single
port pair for mirroring as shown below:
