Enabling wireless LANs (WLANs)

Brocade recommends using the New QoS Policy and Edit QoS Policy screens strategically to name
and configure QoS policies meeting the requirements of the particular WLANs they may to.
However, be careful not to name policies after specific WLANs, as individual QoS policies can be
used by more than one WLAN. For detailed information on assigning QoS policies to specific
WLANs, see
“Creating/editing individual WLANs” on page 107.
To configure QoS policies:
1. Select Network Configuration -> Wireless -> QoS from the Mobility 5181 Access Point menu
tree.
The Quality of Service Configuration screen displays with existing QoS policies and their
current WLAN (if mapped to a WLAN).
NOTE
When the Mobility 5181 Access Point is first launched, a single QoS policy (default) is available
and mapped to WLAN 1. It is anticipated additional QoS policies will be created as the list of
WLANs grows.
2. Click the Create button to configure a new QoS policy, or select a policy and click the Edit
button to modify an existing QoS policy. The access point supports a maximum of 16 QoS
policies.
3. Assign a name to the new or edited QoS policy that makes sense to the Mobility 5181 Access
Point traffic receiving priority. More than one WLAN can use the same QoS policy.
4. Select the Support Voice prioritization check box to allow legacy voice prioritization.
Certain products may not receive priority over other voice or data traffic. Consequently, ensure
the Support Voice Prioritization check box is selected if using products that do not support
Wi-Fi Multimedia (WMM) to provide preferred queuing for these VOIP products.
If the Support Voice Prioritization check box is selected, the access point will detect non-WMM
capable (legacy) phones that connect to the access point and provide priority queueing for
their traffic over normal data.
NOTE
Wi-fi functionality requires both the access point and its associated clients are WMM-capable
and have WMM enabled. WMM enabled devices can take advantage of their QoS functionality
only if using applications that support WMM, and can assign an appropriate priority level to the
traffic streams they generate.
5. Use the two Multicast Address fields to specify one or two MAC addresses to be used for
multicast applications. Some VoIP devices make use of multicast addresses. Using this
mechanism ensures that the multicast packets for these devices are not delayed by the packet
queue.
6. Use the drop-down menu to select the radio traffic best representing the network requirements
of this WLAN. Options include:
manual Select the manual option if intending to manually set the Access
Categories for the radio traffic within this WLAN. Only advanced users
should manually configure the Access Categories, as setting them
inappropriately could negatively impact the access point’s performance.
