load and channel conditions. If the network is not congested, it accepts
the request and grants the client the medium time for its traffic stream.
Otherwise, it rejects the request. This enables the Array to maintain QoS
when the WLAN becomes congested after a connection has already been
established. Some clients contain sufficient intelligence to decide to either
delay the traffic stream, associate with a different AP, or establish a best-
effort traffic stream outside the operation of WMM-Admission Control.
The default setting is Off. Note that the QoS priority of traffic queues is
voice, video, best effort, background—this gives the highest priority to
voice transmissions.
12. WMM ACM Voice: Click On to enable Wireless Multimedia Admission
Control for voice calls. As for WMM ACM Video above, when admission
control for voice is enabled, the Array evaluates a voice request from a
client device against the network load and channel conditions. If the
network is not congested, it accepts the request and grants the client the
medium time for its call. Otherwise, it rejects the request. Some clients
contain sufficient intelligence to decide to either delay the traffic stream,
associate with a different AP, or establish a best-effort traffic stream
outside the operation of WMM-Admission Control. The default setting is
Off.
Station Management
13. Station Re-Authentication Period: This specifies an interval (in seconds)
for station reauthentications. This is the minimum time period between
station authentication attempts, enforced by the Array. This feature is part
of the Xirrus Advanced RF Security Manager (RSM).
14. Station Timeout Period: Specify a time (in seconds) in this field to define
the timeout period for station associations.
15. Max Station Association per Array: This option allows you to define
how many station associations are allowed per Array, or enter unlimited.
Note that the Max Station Association per IAP limit (below) may not be
