Conguring DWL-8220AP Access Points
Changing the Beacon Interval
The beacon interval is the rate at which a radio advertises its beaconed SSID(s). To change
the beacon interval, use the following command:
set radio-prole name beacon-interval interval
The interval can be a value from 25 ms through 8191 ms. The default is 100. The beacon
interval does not change even when advertisement is enabled for multiple SSIDs. MSS still
sends one beacon for each SSID during each beacon interval.
To change the beacon interval for radio prole rp1 to 200 ms, type the following command:
DWS-1008# set radio-prole rp1 beacon-interval 200
success: change accepted.
Changing the DTIM Interval
The DTIM interval species the number of times after every beacon that a radio sends a
delivery trafc indication map (DTIM). An access point sends the multicast and broadcast
frames stored in its buffers to clients who request them in response to the DTIM. The DTIM
interval applies to both the beaconed SSID and the unbeaconed SSID.
The DTIM interval does not apply to unicast frames. A DWL-8220AP access point also stores
unicast frames in buffer memory, but the AP includes information about the buffered unicast
frames in each beacon frame. When a user station receives a beacon frame that advertises
unicast frames destined for the station, the station sends a request for the frames and the AP
transmits the requested frames to the user station.
To change the DTIM interval, use the following command:
set radio-prole name dtim-interval interval
The interval can be a value from 1 through 31. The default is 1.
To change the DTIM interval for radio prole rp1 to 2, type the following command:
DWS-1008# set radio-prole rp1 dtim-interval 2
success: change accepted.
Changing the RTS Threshold
The RTS threshold species the maximum length a frame can be before a radio uses the
Request-to-Send/Clear-to-Send (RTS/CTS) method to send the frame. The RTS/CTS method
clears the air of other trafc to avoid corruption of the frame due to a collision with another
frame.
