Configure RTS Threshold and Retries
Configure RTS Threshold and Retries
The request to send (RTS) threshold determines the packet size at which the wireless device issues an
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 detect each other. You can enter a setting ranging from 0 to 2347 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 32.
To configure the RTS threshold and maximum RTS retries, follow these steps, beginning in privileged
EXEC mode.
SUMMARY STEPS
1. configure terminal
2. interface dot11radio {0| 1}
3. rts threshold value
4. rts retries value
5. end
6. copy running-config startup-config
DETAILED STEPS
Use the no form of the rts command to reset the RTS settings to defaults.
Command Purpose
Step 1
configure terminal Enters global configuration mode.
Step 2
interface dot11radio {0| 1} Enters interface configuration mode for the radio interface. The
2.4-GHz and the 802.11g/n 2.4-GHz radios are radio 0. The
5-GHz and the 802.11n 5-GHz radio is radio 1.
Step 3
rts threshold value Sets the RTS threshold. Enter an RTS threshold from 0 to 2347.
Step 4
rts retries value Sets the maximum RTS retries. Enter a setting from 1 to 128.
Step 5
end Returns to privileged EXEC mode.
Step 6
copy running-config startup-config (Optional) Saves your entries in the configuration file.
