Layer 2 Isolation
27.1 Layer 2 Isolation Overview
Layer-2 isolation is used to prevent connected devices from communicating with each other in the
UAG’s local network(s), on which layer-2 isolation is enabled, except the devices in the white list.
Note: Layer-2 isolation does not check the wireless traffic.
In the following example, layer-2 isolation is enabled on the UAG’s interface Vlan1. A printer, PC
and AP are in the Vlan1. The IP address of network printer (
C
) is added to the white list. The
connected AP then cannot communicate with the PC (
D
), but can access the network printer (
C
),
server (
B
), wireless client (
A
) and the Internet.
