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.

• When VLAN mirroring and port mirroring are both enabled, they must use the same target port.
