In a WMM-enabled association, packets sent from the Bridge
include WMM tags that permit traffic from the Bridge to be
prioritized according to the information contained in those tags.
You can configure WMM for the
STA Interface only in Advanced
View.
3.3.5.6 Station Fragmentation and RTS Thresholds
The
RTS Threshold allows you to configure the maximum size
of the frames the
STA Interface sends without using the RTS/
CTS protocol. Frame sizes over the specified threshold cause
the interface to first send a
Request to Send message and then
receive a
Clear to Send message from the destination device
before transmitting the frame.
The
RTS Threshold is measured in bytes. A value of zero (0)
disables the function (the default), or whole values between
1
and
2345 are accepted.
The
Frag. Threshold allows you to configure the maximum size
of the frames the
STA Interface sends whole. Frame sizes
larger than the specified threshold are broken into smaller
frames before they are transmitted. An acknowledgement is
sent for each frame received, and if no acknowledgement is
sent the frame is retransmitted.
The
Frag. Threshold is measured in bytes. A value of zero (0)
disables the function (the default), or whole values between
256 and 2345 are accepted.
You can configure RTS and fragmentation thresholds only in
Advanced View.
3.3.5.7 Station Unicast Rate Mode and Maximum Rate
NOTE: You can
configure the uni-
cast minimum rate in
the Bridge CLI (refer to
the CLI Software
Guide). On a radio us-
ing any 802.11g band,
the default is
1 Mbps.
On a radio using any
802.11a band, the de-
fault is 6 Mbps.
When a STA Interface is configured to use a Unicast Rate Mode
setting of
auto (the default), the interface dynamically adjusts
the bit rate at which it transmits unicast data frames—throttling
between the configured
Unicast Maximum Rate and the
minimum rate—to provide the optimal data rate for the
connection.
At a
Unicast Rate Mode setting of fixed, the interface will use the
configured
Unicast Maximum Rate for all unicast transmissions.
Transmission rates are set in megabits per second (Mbps).
Unicast Maximum Rate can be set only to a value greater than
or equal to the minimum rate. Usable values for
Unicast
Maximum Rate settings depend on the Band setting for the
radio on which the
STA Interface is configured, as shown in
Table 3.8.
