Enabling wireless LANs (WLANs)
5
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
If using a single-radio access point, there are 4 BSSIDs available. If using a dual-radio access
point, 4 BSSIDs for the 802.11b/g radio and 4 BSSIDs for the 802.11a radio are available.
RTS Threshold RTS allows the Mobility 5181 Access Point to use RTS (Request To Send) on
frames longer than the specified length.
The default is 2341bytes.
Set RF QoS Click the Set RF QoS button to display the Set RF QOS screen to set QoS
parameters for the radio. Do not confuse with the QoS configuration screen
used for a WLAN. The Set RF QoS screen initially appears with default
values displayed.
Select manual from the Select Parameter set drop-down menu to edit the
CW min and CW max (contention window), AIFSN (Arbitrary Inter-Frame
Space Number) and TXOPs Time for each Access Category. These are the
QoS policies for the 802.11a or 802.11b/g radio, not the QoS policies
configured for the WLAN (as created or edited from the Quality of Service
Configuration screen).
Brocade recommends only advanced users manually set these values. If
the type of data-traffic is known, use the drop-down menu to select a
11g-wifi, 11b-wifi, 11g-default, 11b-default, 11g-voice or
11b-voice
option. Wifi represents multimedia traffic, default is typical data traffic and
voice is for “Voice-Over-IP” supported wireless devices.
Click OK to implement the selected QoS values and return to the 802.11a
or 802.11b/g radio configuration screen. Clicking Cancel reverts the screen
to the last saved configuration.
WLAN Lists the WLAN names available to the 802.11a or 802.11b/g radio that can be
assigned to a BSSID.
BSSID Assign a BSSID value of 1 through 4 to a WLAN in order to map the WLAN to a
specific BSSID.
BC/MC Cipher A read only field displaying the downgraded BC/MC (Broadcast/Multicast)
cipher for a WLAN based on the BSSID and VLAN ID to which it has been
mapped.
Status Displays the following color coded status:
Red - Error (Invalid Configuration)
Yellow - Warning (Broadcast Downgrade)
Green - Good (Configuration is OK)
Message Displays the verbal status of the WLAN and BSSID assignments. If the Status
column displays green, the Message will typically be Configuration is OK. If
yellow, a description of invalid configuration displays.
