dtim-period
This command configures the rate at which stations in sleep mode must wake up to receive
broadcast/multicast transmissions.
broadcast/multicast transmissions.
Syntax
dtim-period <interval>
interval is the interval between the beacon frames that transmit broadcast or multicast traffic.
Range: 1‐255 beacon frames
Range: 1‐255 beacon frames
Default Setting
2

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.
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.
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.
