rts-cts-mode

rts-cts-mode

Function

The rts-cts-mode command sets the request to send (RTS)-clear to send (CTS) operation mode in a radio profile.

The undo rts-cts-mode command restores the default RTS-CTS operation mode in a radio profile.

By default, the RTS-CTS operation mode is rts-cts.

Format

rts-cts-mode { cts-to-self | disable | rts-cts }

undo rts-cts-mode

Parameters

Usage Guidelines

  • In rts-cts mode, when an AP needs to send data to a STA, the AP sends an RTS packet to all STAs associated with it. After receiving the RTS packet, none of the devices within the AP's coverage area sends data within a specified period. After the destination STA receives the RTS packet, it sends a CTS packet. After receiving the CTS packet, none of the devices within the STA's coverage area sends data within a specified period. Using the rts-cts mode to avoid conflicts requires two packets (RTS and CTS packets), increasing packet overhead.
  • In cts-to-self mode, when an AP needs to send data to STAs, it sends a CTS packet with its IP address as the source and destination addresses. Then none of the devices within the AP's coverage area sends data within a specified period. In cts-to-self mode, an AP only needs to send a CTS packet to avoid channel conflicts in most scenarios. However, if there is a device within the STA's coverage area but not within the AP's coverage area, a channel conflict may still occur.

Compared to the rts-cts mode, the cts-to-self mode reduces the number of control packets sent on the network. In some situations, however, a channel conflict may still occur when hidden nodes do not receive the CTS packet from the AP. Therefore, the rts-cts mode is more effective in avoiding channel conflicts than the cts-to-self mode.

To avoid a data transmission failure caused by channel conflicts, run the rts-cts-mode command to set the RTS-CTS operation mode in a radio profile according to networking requirements.

Example

# Set the RTS-CTS operation mode to rts-cts in the 2G radio profile.
