Configuration notes

A port is disabled only if a packet is looped back to that same port. Loop detection must be
configured on the physical port.

Port mirroring and monitoring

You can monitor the traffic on the Brocade ports by configuring another port to mirror the traffic on
the ports you want to monitor. The port thus configured is called a mirror port. By attaching a
protocol analyzer to the mirror port, you can observe the traffic on the monitored ports.

Port mirroring show commands

Syntax: show port monitor [interface | vlan vlan-id | mac-address mac-address]

interface - ethernet unit/port (source port)

unit - Unit identifier. (Range: 1)

port - Port number. (Range: 1-12)

vlan-id - VLAN ID (Range: 1-4093)
