Configuring Radio Settings
Configuring RTS Threshold and Retries
The RTS threshold determines the packet size at which the bridge issues a request to send (RTS) before
sending the packet. You can enter a setting ranging from 0 to 4000 bytes. If your bridge link is a
point-to-point configuration, set the RTS threshold to 4000 on both the root and non-root bridges. If you
have multiple bridges set up in a point-to-multipoint configuration, set the RTS threshold to 4000 on the
root bridge and to 0 on the non-root bridges.
Maximum RTS Retries is the maximum number of times the bridge 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 4000, and the default maximum RTS retries setting is 32. Beginning in
privileged EXEC mode, follow these steps to configure the RTS threshold and maximum RTS retries:
Command
Step 1
configure terminal
Step 2
interface dot11radio 0
Step 3
rts threshold value
Step 4
rts retries value
Step 5
end
Step 6
copy running-config startup-config (Optional) Save your entries in the configuration file.
Use the no form of the command to reset the RTS settings to defaults.
Configuring the Maximum Data Retries
The maximum data retries setting determines the number of attempts the bridge makes to send a packet
before giving up and dropping the packet.
The default setting is 32. Beginning in privileged EXEC mode, follow these steps to configure the
maximum data retries:
Command
Step 1
configure terminal
Step 2
interface dot11radio 0
Step 3
packet retries value
Step 4
end
Step 5
copy running-config startup-config (Optional) Save your entries in the configuration file.
Use the no form of the command to reset the setting to defaults.
