Default command level
2: System level
Parameters
cts-to-self: Specifies the Clear to Send (CTS)-to-Self collision avoidance mechanism.
rts-cts: Specifies the Request to Send (RTS)/CTS collision avoidance mechanism.
Usage guidelines
Compared with RTS/CTS, CTS-to-Self reduces the number of control frames. However, data collisions still
occur when some clients are hidden and thus cannot receive the CTS frames sent by the AP. Therefore, the
RTS/CTS mechanism can solve the data collision problem in a larger coverage than RTS/CTS.
For more information about CTS-to-Self and RTS/CTS, see WLAN Configuration Guide.
Examples
# Configure the collision avoidance mechanism as RTS/CTS.
