Chapter 7 Wireless
wireless station A and B can still access the wired network but cannot communicate with each other.
Figure 37 Basic Service set
7.9.6 MBSSID
Traditionally, you need to use different APs to configure different Basic Service Sets (BSSs). As well as the cost of buying extra APs, there is also the possibility of channel interference. The ZyXEL Device’s MBSSID (Multiple Basic Service Set IDentifier) function allows you to use one access point to provide several BSSs simultaneously. You can then assign varying QoS priorities and/or security modes to different SSIDs.
Wireless devices can use different BSSIDs to associate with the same AP.
7.9.6.1Notes on Multiple BSSs
•A maximum of eight BSSs are allowed on one AP simultaneously.
•You must use different keys for different BSSs. If two wireless devices have different BSSIDs (they are in different BSSs), but have the same keys, they may hear each other’s communications (but not communicate with each other).
•MBSSID should not replace but rather be used in conjunction with 802.1x security.
