Using A Mirror Port For Analysis - Planet Networking & Communication WGS3-2620 User Manual

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.

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.
