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.
