4.5.2.2 Using 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
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 included in
the same VLAN as the source port. (See “Configuring Virtual LANs”)
You can use the Port Mirror Configuration screen to mirror one or more ports to the monitor port as
shown below.
Parameter Description
Port Mirroring Enables or disables the mirror function.
Mirrored Ports (Tx/Rx) The port whose transmitted or received traffic will be mirrored. Press Add
to specify mirrored ports.
Monitor Port The port that will duplicate the transmitted or received traffic appearing on
the mirrored port.
NOTE: You can mirror multiple ports to a single port to view traffic on WGS3-2620. However, note
that some packets may be dropped for moderate to heavy loading.
