Enabling Wireless LANs (WLANs)
5
6. Refer to the QBSS Load Element Settings field to determine whether channel usage data is
transmitted to associated devices.
7. Select the Advanced Settings tab to strategically map BSSIDs to WLANs in order to define them
as primary WLANs.
Defining Primary WLANs allows an administrator to dedicate BSSIDs (4 BSSIDs are available
for mapping) to WLANs. From that initial BSSID assignment, Primary WLANs can be defined
from within the WLANs assigned to BSSID groups 1 through 4. Each BSSID beacons only on
the primary WLAN.
The user should assign each WLAN to its own BSSID. In cases where more than four WLANs
are required, WLANs should be grouped according to their security policies so all of the WLANs
on a BSSID have the same security policy. It is generally a bad idea to have WLANs with
different security policies on the same BSSID, as this will result in warning or error messages.
NOTE
When using a Brocade Mobility 7131N-FGR Access Point dual-radio access point, 4 BSSIDs for
the 802.11b/g/n radio and 4 BSSIDs for the 802.11a/n radio are available.
Enable QBSS load
element When enabled, the access point communicates channel usage
data to associated devices using an interval you define. The QBSS
load represents the percentage of time the channel is in use by
the access point and the access point’s MU count. This
information is helpful in assessing the access point’s overall load
on a channel, its availability for additional device associations and
multi media traffic support. This setting is enabled by default.
QBSS Beacon Interval Set the QBSS beacon (transmission) interval the access point uses
for sending QBSS data to associated devices.
