Port mirroring configuration rules
The following configuration rules apply to any port mirroring configuration:
• You cannot configure a monitor port as a trunk member or IGMP member.
• A monitor port cannot be used for normal switch functions.
• When you configure a port as a monitor port, the port is automatically
disabled from participating in the spanning tree. When you reconfigure the
port as a standard switch port (no longer a monitor port), the port is enabled
for spanning tree participation.
• When you create 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 Chapter 3).
