Wireless Interface Commands
BreezeMAX Wi² and BreezeACCESS Wi² System Manual 217
Syntax
dtim-period <interval>
interval - Interval between the beacon frames that transmit broadcast or multicast traffic.
(Range: 1-255 beacon frames)
Default Setting
1
Command Mode
Interface Configuration (Wireless)
Command Usage
• The Delivery Traffic Indication Map (DTIM) packet interval value indicates how often the MAC
layer forwards broadcast/multicast traffic. This parameter is necessary to wake up stations that
are using Power Save mode.
• The DTIM is the interval between two synchronous frames with broadcast/multicast information.
The default value of 2 indicates that the AP will save all broadcast/multicast frames for the Basic
Service Set (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.
Example
5.18.14 fragmentation-length
This command configures the minimum packet size that can be fragmented when
passing through the AP.
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.
