dtim-period

This command configures the frequency at which stations sleeping in low-
power mode should wake up to receive broadcast/multicast transmissions.
Syntax
dtim-period <value>
• value - Interval between the beacon frames that transmit broadcast or
multicast traffic. Setting this value to "2", allows stations to check on
every other beacon. (Range: 1-255 beacon frames)
Default Setting
2
Command Mode
WLAN Interface Configuration
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.
