The following configuration rules apply to any port mirroring configuration:

•

A monitor port cannot be configured as a trunk member or IGMP member, 
and cannot be used for normal switch functions.

•

When a port is configured and enabled as a monitor port, the port is 
automatically disabled from participating in the spanning tree. When the port 
is reconfigured as a standard switch port (no longer a monitor port), the port 
becomes enabled for spanning tree participation.

•

When creating a port-based port mirroring configuration, be sure that the 
monitor port and both of the mirrored ports, port X and port Y, have the same 
configuration. Use the VLAN Configuration screen to configure the VLAN 
(see 

).

•

VLAN configuration settings for any ports configured for port-based 
mirroring cannot be changed. Use the Port Mirroring Configuration screen to 
disable port mirroring (or reconfigure the port mirroring ports), then change 
the VLAN configuration settings.

•

For port-based monitoring of traffic, use one of the following modes for 
monitoring broadcast, IP multicast, or unknown DA frames:

-- Monitor all traffic received by port X.

-- Monitor all traffic transmitted by port X.

-- Monitor all traffic received and transmitted by port X.
