• 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
access point 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.

length - Minimum packet size for which fragmentation is allowed.

Interface Configuration (Wireless)
• 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
