Multiple SSIDs
Q. What Are BSSIDs and SSIDs?
A. BSSID (Basic Service Set Identifier) refers to an individual access point
radio and its associated clients. The identifier is the MAC address of the
access point radio that forms the BSS.
A group of BSSs can be formed to allow stations in one BSS to
communicate to stations in another BSS by way of a backbone that
interconnects each access point.
The Extended Service Set (ESS) refers to the group of BSSIDs that are
grouped together to form one ESS. The ESSID (often referred to as SSID or
“wireless network name”) identifies the Extended Service Set. Clients
must associate to a single ESS at any given time. Clients ignore traffic
from other Extended Service Sets that do not have the same SSID.
Legacy access points typically support one SSID per access point. Xirrus
Wireless APs support the ability for multiple SSIDs to be defined and
used simultaneously.
Q. What would I use SSIDs for?
A. The creation of different wireless network names allows system
administrators to separate types of users with different requirements. The
following policies can be tied to an SSID:
