Traffic on LAG port e 1/1/2 is monitored, and the monitored traffic is copied to port e 1/1/1, the mirror
port.
Mirroring configuration on a traditional stack
You can configure mirroring on a Brocade traditional stack. A traditional stack consists of up to eight
FCX and ICX 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 traditional stack mirroring
The following mirroring configuration information applies to all FCX and ICX devices connected in a
traditional stack topology:
• The input or output mirroring port can be on different ports.
• All FastIron devices 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 traditional stack.
• If the mirror port and the monitored ports are on the same port region, multiple active mirror ports are
allowed for the entire traditional stack. Devices in a traditional stack support 24 ports per port region.
• The maximum number of monitored VLANs on a traditional stack is 8.
Configuring mirroring for ports on different members in a traditional stack example
In this example, although two ports are configured as active ports, only one active mirror port (port
1/1/24) is allowed for the entire stack because the mirror ports and the monitored ports are on different
stack members.
