Similarly, when configuring the Wireless Edge Services xl Module, you are

SSID Versus BSSID
As indicated above, the SSID identifies a group of BSSs that make up a single
WLAN. All frames transmitted in a WLAN are marked with this SSID. Wireless
media can be very busy, and wireless devices limit the number of superfluous
frames that they must process by accepting only frames marked with the SSID
of their WLAN.
