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 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 included in the same VLAN as the
source port. (See “VLAN Static List” on page 3-26.)
You can use the port mirror configuration screen to designate a single port pair for
mirroring as shown below.
