Configuring VLAN Mirroring
Use the VLAN > Mirror (Add) page to mirror traffic from one or more source VLANs
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 VLAN(s) in a
completely unobtrusive manner.
Command Usage
All active ports in a source VLAN are monitored for ingress traffic only.
All VLAN mirror sessions must share the same target port, preferably one that is
not a member of the source VLAN.
