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.
Figure 61: Configuring Local Port Mirroring
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
(remote port mirroring as described in
“Configuring Remote Port Mirroring” on
page 130 ).
◆
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.
