Configuring the Beacon Period and the DTIM
The beacon period is the amount of time between access point beacons in kilomicroseconds
(Kmicrosecs). One Kmicrosec equals 1,024 microseconds. The data beacon rate, always a multiple of
the beacon period, determines how often the beacon contains a delivery traffic indication message
(DTIM). The DTIM tells power-save client devices that a packet is waiting for them.
For example, if the beacon period is set at 100, its default setting, and if the data beacon rate is set at 2,
its default setting, then the wireless device sends a beacon containing a DTIM every 200 Kmicrosecs.
The default beacon period is 100, and the default DTIM is 2. To configure the beacon period and the
DTIM, follow these steps, beginning in privileged EXEC mode.

}
Enters interface configuration mode for the radio interface. The
802.11g/n 2.4-GHz radio is radio 0.
The 802.11n 5-GHz radio is radio 1.
Step 3
beacon period
value
Sets the beacon period. Enter a value in kilomicroseconds.
Step 4
beacon dtim-period
value
Sets the DTIM. Enter a value in kilomicroseconds.
Step 5
end
Returns to privileged EXEC mode.
Step 6
