System Configuration
(BSS) and forward them after every second beacon. Using smaller DTIM intervals
delivers broadcast/multicast frames in a more timely manner, causing stations in
Power Save mode to wake up more often and drain power faster. Using higher DTIM
values reduces the power used by stations in Power Save mode, but delays the
transmission of broadcast/multicast frames.
(Range: 1-255 beacons; Default: 2 beacons)
Fragment Length – Configures the minimum packet size that can be fragmented
when passing through the wireless bridge. Fragmentation of the PDUs (Package
Data Unit) can increase the reliability of transmissions because it increases the
probability of a successful transmission due to smaller frame size. If there is
significant interference present, or collisions due to high network utilization, try
setting the fragment size to send smaller fragments. This will speed up the
retransmission of smaller frames. However, it is more efficient to set the fragment
size larger if very little or no interference is present because it requires overhead to
send multiple frames. (Range: 256-2346 bytes; Default: 2346 bytes)
RTS Threshold – Sets the packet size threshold at which a Request to Send (RTS)
signal must be sent to a receiving station prior to the sending station starting
communications. The wireless bridge sends RTS frames to a receiving station to
negotiate the sending of a data frame. After receiving an RTS frame, the station
sends a CTS (clear to send) frame to notify the sending station that it can start
sending data.
If the RTS threshold is set to 0, the wireless bridge never sends RTS signals. If set
to 2347, the wireless bridge always sends RTS signals. If set to any other value, and
the packet size equals or exceeds the RTS threshold, the RTS/CTS (Request to
Send / Clear to Send) mechanism will be enabled.
The wireless bridges contending for the medium may not be aware of each other.
The RTS/CTS mechanism can solve this "Hidden Node Problem." (Range: 0-2347
bytes: Default: 2347 bytes)
Maximum Associations – (Access point mode only) Sets the maximum number of
clients that can be associated with the access point radio at the same time.
(Range: 1-64 per radio: Default: 64)
CLI Commands for the 802.11a Wireless Interface – From the global configuration
mode, enter the command to access the 802.11a radio
interface wireless a
