Using the Command Line Interface
fragmentation-length
This command configures the minimum packet size that can be fragmented when
passing through the access point.
Syntax
fragmentation-length <length>
length - Minimum packet size for which fragmentation is allowed.
(Range: 256-2346 bytes)
Default Setting
2346
Command Mode
Interface Configuration (Wireless)
Command Usage
• If the packet size is smaller than the preset Fragment size, the packet will
not be segmented.
• 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.
Example
rts-threshold
This command sets the packet size threshold at which a Request to Send (RTS)
signal must be sent to the receiving station prior to the sending station starting
communications.
Syntax
rts-threshold <threshold>
threshold - Threshold packet size for which to send an RTS.
