252 Configuring APsNN47250-500 (320657-F Version 02.01)The DTIM interval does not apply to unicast frames. An AP also stores unicast frames in buffer memory, but the APincludes information about the buffered unicast frames in each beacon frame. When a user station receives a beaconframe that advertises unicast frames destined for the station, the station sends a request for the frames and the APtransmits the requested frames to the user station.To change the DTIM interval, use the following command:set radio-profile name dtim-interval intervalThe 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:WSS# set radio-profile rp1 dtim-interval 2success: change accepted.Changing the RTS thresholdThe 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 theframe 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 thereceiver. 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 theacknowledgment message.To change the RTS threshold, use the following command:set radio-profile name rts-threshold thresholdThe 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:WSS# set radio-profile rp1 rts-threshold 1500success: change accepted.Changing the fragmentation thresholdThe fragmentation threshold specifies the longest a frame can be without being fragmented into multiple frames by aradio before transmission. To change the fragmentation threshold, use the following command:set radio-profile name frag-threshold thresholdThe threshold can be a value from 256 through 2346. The default is 2346.To change the fragmentation threshold for radio profile rp1 to 1500 bytes, type the following command:WSS# set radio-profile rp1 frag-threshold 1500success: change accepted.
