Wi-Fi Multimedia (WMM)
– 86 –
◆ Rogue AP Scan Result — Displays information of unknown APs detected
within the range of the AP running the scan.
◆ Friendly Active AP Scan Result — Displays information of known APs
detected within the range of the AP running the scan.
◆ Start Instant Scan — Starts an immediate rogue AP scan on the radio
interface. (Default: Disable)
Note:
While the access point scans a channel for rogue APs, wireless clients will not
be able to connect to the access point. Therefore, avoid frequent scanning or scans
of a long duration unless there is a reason to believe that more intensive scanning is
required to find a rogue AP.
Wi-Fi Multimedia (WMM)
Wireless networks offer an equal opportunity for all devices to transmit data from
any type of application. Although this is acceptable for most applications,
multimedia applications (with audio and video) are particularly sensitive to the
delay and throughput variations that result from this “equal opportunity” wireless
access method. For multimedia applications to run well over a wireless network, a
Quality of Service (QoS) mechanism is required to prioritize traffic types and
provide an “enhanced opportunity” wireless access method.
The access point implements QoS using the Wi-Fi Multimedia (WMM) standard.
Using WMM, the access point is able to prioritize traffic and optimize performance
when multiple applications compete for wireless network bandwidth at the same
time. WMM employs techniques that are a subset of the IEEE 802.11e QoS standard
and it enables the access point to interoperate with both WMM-enabled clients and
other devices that may lack any WMM functionality.
Access Categories — WMM defines four access categories (ACs): voice, video, best
effort, and background. These categories correspond to traffic priority levels and
are mapped to IEEE 802.1D priority tags (see “WMM Access Categories” on
page 87). The direct mapping of the four ACs to 802.1D priorities is specifically
intended to facilitate inter operability with other wired network QoS policies. While
the four ACs are specified for specific types of traffic, WMM allows the priority levels
to be configured to match any network-wide QoS policy. WMM also specifies a
protocol that access points can use to communicate the configured traffic priority
levels to QoS-enabled wireless clients.
