Creating the Port Mirror or Adding New Source Ports
The command to create the port mirror is the MIRROR INTERFACE
command. You must perform this command from the Port Interface mode
of the destination port of the port mirror. The command has this format:
mirror interface source_ports direction
receive|transmit|both
This example configures the port mirror to copy the ingress traffic on the
source port 3 to the destination port 5:
awplus> enable
awplus# configure terminal
awplus(config)# interface port1.0.5
awplus(config-if)# mirror interface port1.0.3 direction
receive
The switch immediately begins to copy the monitored traffic from the
source ports to the destination port as soon as you create the port mirror.
To add new source ports to the port mirror, return to the Port Interface
mode of the destination port and enter the same command. For example,
to monitor both the ingress and egress traffic on ports 11 and 12 to the
destination port 5, you enter:
awplus> enable
awplus# configure terminal
awplus(config)# interface port1.0.5
awplus(config-if)# mirror interface port1.0.11-port1.0.12
direction both
