Mbssid; Wireless Distribution System (Wds) - ZyXEL Communications PMG5318-B20A User Manual

Chapter 6 Wireless LAN
When Intra-BSS traffic blocking is enabled, wireless station A and B can still access the wired
network but cannot communicate with each other.

6.9.6 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 GPON
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.
6.9.6.1 Notes 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.

6.9.7 Wireless Distribution System (WDS)

The GPON Device can act as a wireless network bridge and establish WDS (Wireless Distribution
System) links with other APs. You need to know the MAC addresses of the APs you want to link to.
