5.7.1.2 Using 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
packet 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 “5.7.3.2 VLAN Table Configuration”)
