dtim-interval
Usage Guidelines
DTIM refers to delivery traffic indication map. After a STA enters the dormancy mode, the associated AP saves the broadcast and multicast frames for the STA. When a Beacon frame sent to the STA by the AP contains DTIM, the saved broadcast and multicast frames will be transmitted to the STA. The DTIM interval refers to the number of Beacon frames sent before the Beacon frame that contains the DTIM. To set the interval for sending Beacon frames in an SSID profile, run the beacon-interval command.
- When the STA is in the dormancy status, the AP saves data transmitted to the STA and notifies the STA with a bit in broadcast Beacon frames. The STA receives data according to this bit. You can run this command to set the DTIM interval in the specified SSID profile.
- The DTIM interval specifies how many Beacon frames are sent before the Beacon frame that contains the DTIM. A long DTIM interval lengthens the dormancy time of the STA and saves power, but degrades the transmission capability of the STA. A short interval helps transmitting data in a timely manner, but the STA is waken up frequently, causing high power consumption.
