Changing The Dtim Interval; Changing The Rts Threshold - D-Link DWS-1008 - AirPremier MobileLAN Switch Product Manual

The DTIM interval specifies the number of times after every beacon that a radio sends a delivery traffic
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. An 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-profile 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 profile rp1 to 2, type the following command:
DWS-1008# set radio-profile rp1 dtim-interval 2
success: change accepted.
The RTS threshold specifies 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
traffic to avoid corruption of the frame due to a collision with another frame.
When a frame is long enough for the RTS/CTS method to be applicable, the radio sends a Request-
To-Send (RTS) message addressed to the intended receiver for the frame. The receiver replies with
a Clear-To-Send (CTS) message. When the radio receives the CTS message, the radio transmits the
frame and waits for an acknowledgment from the receiver. The radio does not transmit additional frames
until receiving the acknowledgment.
Any other user station that overhears the RTS or CTS message stops transmitting until the station
overhears the acknowledgment message.
To change the RTS threshold, use the following command:
set radio-profile name rts-threshold threshold
The threshold can be a value from 256 bytes through 3000 bytes. The default is 2346.
To change the RTS threshold for radio profile rp1 to 1500 bytes, type the following command:
DWS-1008# set radio-profile rp1 rts-threshold 1500
success: change accepted.
