The beacon signals allow wireless clients to maintain contact with the access
point. They may also carry power-management information.
Example
dtim-period
This command configures the rate at which stations in sleep mode must wake up to
receive broadcast/multicast transmissions.
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 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.
Example
fragmentation-length
This command configures the minimum packet size that can be fragmented when
passing through the access point.
