Port mirroring and monitoring
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
show port monitor
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)
mac-address - MAC address in the form of xx-xx-xx-xx-xx-xx or xxxxxxxxxxxx.
This command displays the configuration settings for inbound or outbound traffic that is being
mirrored to each mirror port, as shown in the following example.
