Dual work mode

Figure 1-8 Dual work mod

Dual work mode indicates that an AC can provide both master and slave connections. An AC will act as

the master for some APs and act as the slave for some other APs. In the above scenario, AC 1 acts as

the master for AP 1 and slave for AP 2. Similarly, AC 2 acts as the master for AP 2 and slave for AP 1.

WLAN Topologies

WLAN Topologies for ACs

WLAN topologies for ACs consist of:

z Single BSS

z Multi-ESS

z VLAN-based WLAN

z Centralized WLAN

Single BSS

The coverage of an AP is called a basic service set (BSS). Each BSS is identified by a BSSID. The most

basic WLAN network can be established with only one BSS. All wireless clients associate with the same

BSS. If these clients have the same authorization, they can communicate with each other.

Figure 1-9

shows a single-BSS WLAN.
