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

Outdoor 11a Building to Building (if-wireless g)#fragmentation-length 512 Outdoor 11a Building to Building (if-wireless g)#

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. (Range: 0-2347 bytes)

6-123
