Chapter 6 Configuring Radio Settings
Configure RTS Threshold and Retries
Configure RTS Threshold and Retries
The RTS threshold determines the packet size at which the wireless device issues a request to send (RTS)
before sending the packet. A low RTS Threshold setting can be useful in areas where many client devices
are associating with the wireless device, or in areas where the clients are far apart and can detect only
the wireless device and not each other. You can enter a setting ranging from 0 to 23472347 bytes.
Maximum RTS retries is the maximum number of times the wireless device issues an RTS before
stopping the attempt to send the packet over the radio. Enter a value from 1 to 128.
The default RTS threshold is 2347 for all access points and bridges, and the default maximum RTS
retries setting is 3264. Beginning in privileged EXEC mode, follow these steps to configure the RTS
threshold and maximum RTS retries:
Use the no form of the command to reset the RTS settings to defaults.
Step 4
beacon dtim-period value Set the DTIM. Enter a value in Kilomicroseconds.
Step 5
end Return to privileged EXEC mode.
Step 6
copy running-config startup-config (Optional) Save your entries in the configuration file.
