mirroring configuration on an IronStack
To display the port monitoring configuration, enter the show monitor and show mirror commands.
Monitoring an individual trunk port
You can monitor the traffic on an individual port of a static trunk group, and on an individual port of
an LACP trunk group.
By default, when you monitor the primary port in a trunk group, aggregated traffic for all the ports in
the trunk group is copied to the mirror port. You can configure the device to monitor individual ports
in a trunk group. You can monitor the primary port or a secondary port individually.
To configure port monitoring on an individual port in a trunk group, enter commands such as the
following.
Brocade(config)#mirror-port ethernet 2/6
Brocade(config)#trunk e 2/2 to 2/5
Brocade(config-trunk-2/2-2/5)#config-trunk-ind
Brocade(config-trunk-2/2-2/5)#monitor ethe-port-monitored 2/4 ethernet 2/6 in
Traffic on trunk port e 2/4 is monitored, and the monitored traffic is copied to port e 2/6, the mirror
port.
The config-trunk-ind command enables configuration of individual ports in the trunk group. You
enter the config-trunk-ind command only once in a trunk group. After you enter the command, all
applicable port configuration commands apply to individual ports only.
NOTE
If you enter no config-trunk-ind, all port configuration commands are removed from the individual
ports and the configuration of the primary port is applied to all the ports. Also, once you enter the
no config-trunk-ind command, the enable, disable, and monitor commands are valid only on the
primary port and apply to the entire trunk group.
mirroring configuration on an IronStack
You can configure mirroring on a Brocade IronStack. An IronStack consists of up to eight FCX
devices. The stack operates as a chassis. The following examples show how to configure mirroring
for ports that are on different members of a stack, and for ports that are on the same stack
member as the mirror port.
Configuration notes for Ironstack mirroring
The following mirroring configuration information applies to FCX devices connected in an IronStack
topology:
• The input or output mirroring port can be on different ports.
• An IronStack can have one mirroring port that monitors multiple ports, but cannot have
multiple mirror ports for one monitored port.
• If the mirror port and the monitored ports are on different stack units, only one active mirror
port is allowed for the entire IronStack.
• If the mirror port and the monitored ports are on the same port region, multiple active mirror
ports are allowed for the entire IronStack. Devices in an IronStack support 24 ports per port
region.
