Fragmentation-Length - HP ProCurve 420 Management And Configuration Manual

Command Line Reference
Interface Commands
6-74
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 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.

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)

Command Usage
• If the packet size is smaller than the preset fragment size, the packet
will not be fragmented.
• 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 signifi-
