Port Mirroring - Allied Telesis AT-x900-12XT/S Configuration Manual

Port mirroring

This example shows how to send port 1.0.23 a copy of all traffic that ingresses and egresses
port 1.0.2.
In other words, port 1.0.23 is the mirror port, and port 1.0.2 is the port that is being
mirrored.
First, enter Global Configuration mode and enter the command:
awplus(config)#interface port1.0.23
This puts you in Interface Configuration mode for port1.0.23. Then enter the command:
awplus(config-if)#mirror interface port1.0.2 direction both
To check the configuration, enter Privileged Exec mode and enter the command:
awplus#show mirror
The output looks like this:
Mirror Test Port Name: port1.0.23
Mirror option: Enabled
Mirror direction: both
Monitored Port Name: port1.0.2
