Chapter 1 Introducing the NWA

In the figure below, A and B use X as an AP to access the wired network, while X and Y communicate in bridge mode.

When the NWA is in AP + Bridge mode, security between APs (the Wireless Distribution System or WDS) is independent of the security between the wireless stations and the AP. If you do not enable WDS security, traffic between APs is not encrypted. When WDS security is enabled, both APs must use the same pre- shared key. See Section 8.4.3 on page 129 for more details.

Unless specified, the term “security settings” refers to the traffic between the wireless stations and the NWA.

1.2.4 MBSSID

A BSS (Basic Service Set) is the set of devices forming a single wireless network (usually an access point and one or more wireless clients). An SSID (Service Set IDentifier) is the name of a BSS. In MBSSID (Multiple BSS) mode, the NWA provides multiple virtual APs, each forming its own BSS and using its own individual SSID profile.

You can configure up to sixteen SSID profiles, and have up to eight active at any one time.

You can assign different wireless and security settings to each SSID profile. This allows you to compartmentalize groups of users, set varying access privileges, and prioritize network traffic to and from certain BSSs.
