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.
