The rts-cts-threshold command sets the RTS-CTS threshold in a radio profile.
The undo rts-cts-threshold command restores the default RTS-CTS threshold in a radio profile.
The default RTS-CTS alarm threshold is 1400 bytes.

---|---|---|
rts-cts-threshold |
Specifies the RTS-CTS threshold. If the length of a frame to be sent by the MAC Layer exceeds this threshold, an RTS frame needs to be sent before this frame. |
The value is an integer that ranges from 64 to 2347, in bytes. |
The IEEE 802.11 MAC protocol provides an RTS-CTS handshake protocol to prevent conflicts between channels and failure to transmit data. STA A sends an RTS frame before sending data to STA B. STA A can send data after receiving a CTS frame from STA B. If multiple STAs send RTS frames to a STA, only the STA that receives a CTS frame can send data, and other STAs have channel conflicts by default and must wait and send RTS frames again.
If STAs implement RTS-CTS handshakes before sending data, the channel bandwidth is consumed by too much RTS frames. You can set an RTS threshold to specify the length of frames to be sent. When the length of frames to be sent by the STA is smaller than the RTS threshold, no RTS/CTS handshake is implemented.
