CHAPTER 12
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.
