Port Configuration
FIGURE 34 Displaying Port Information
Configuring Local Port Mirroring
Use the Interface > Port > 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.

CLI References
• “Local Port Mirroring Commands” on page 297
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 706).
• Monitor port speed should match or exceed source port speed, otherwise traffic may be
dropped from the monitor port.
• Note that Spanning Tree BPDU packets are not mirrored to the target port.
• When mirroring VLAN traffic (see “Configuring VLAN Mirroring” on page 775) or packets based
on a source MAC address (see “Configuring MAC Address Mirroring” on page 783), the target
port cannot be set to the same target ports as that used for port mirroring by this command.
• The destination port cannot be a trunk or trunk member port.
Parameters
These parameters are displayed:
• Source Port – The port whose traffic will be monitored.
• Target Port – The port that will mirror the traffic on the source port.
