Mirror Port
All traffic that goes through one or more LAN ports of the appliance can be duplicated into one
designated mirror port. For example, all traffic that passes through LAN1 and LAN2 is
duplicated into LAN5, which is configured as the mirror port. You can only configure one mirror
port at a time.
Use Case – If an external device is connected to the mirror port, it receives all traffic that goes
through LAN1/LAN2 of the appliance. This enables you to monitor traffic that goes through the
appliance from the external device.
The mirror port is the opposite of the existing monitor port feature, in which the traffic from an
external source such as a network switch or router goes into the (WAN) port of the appliance,
so the appliance can inspect the traffic going through the external source.
