Layer-2 Isolation Screen
12.1 Overview
Layer-2 isolation is used to prevent wireless clients associated with your NWA
from communicating with other wireless clients, APs, computers or routers in a
network.
In the following figure, layer-2 isolation is enabled on the NWA ( Z ) to allow a
guest wireless client ( A ) to access the main network router ( B ). The router
provides access to the Internet and the network printer ( D ) while preventing the
client from accessing other computers and servers on the network. The client can
communicate with other wireless clients only if
Intra-BSS Traffic blocking is
disabled.
Note: Intra-BSS Traffic Blocking is activated when you enable layer-2 isolation.
