Port Mirroring Configuration Rules

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” on page 3-41).

• 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.

For more information about using the Port Mirroring feature, see “

Port Mirroring

Configuration” on page 3-65.

Also see Appendix C, “

Quick Steps to Features,” for configuration flowcharts that

can help you use this feature.
