Configuring Local Port Mirroring
Use the Interface > Mirror page to 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.
Command Usage
Traffic can be mirrored from one or more source ports to a destination port on the same switch (local port mirroring as
described in this section), or from one or more source ports on remote switches to a destination port on this switch.
Monitor port speed should match or exceed source port speed, otherwise traffic may be dropped from the monitor port.
The destination port cannot be a trunk or trunk member port.
Note that Spanning Tree BPDU packets are not mirrored to the target port.
