Beacon Period and DTIM
You can customize the beacon period and DTIM on a WLC and AP.
For an autonomous AP you can use :
AP5(config-if)#beacon period ?
20-4000 Kusec (or msec)
AP5(config-if)#beacon dtim-period ?
1-100 dtim count
The DTIM count should be between 1 and 255.
At the WCS you can put the same values like the WLC’s. There is no difference.
