Configuring the Maximum Data Retries
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 wireless device 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:
Use the no form of the command to reset the setting to defaults.
Configuring the Fragmentation Threshold
The fragmentation threshold determines the size at which packets are fragmented (sent as several pieces
instead of as one block). Use a low setting in areas where communication is poor or where there is a great
deal of radio interference.
The default setting is 2338 bytes. Beginning in privileged EXEC mode, follow these steps to configure
the fragmentation threshold:
Step 5
end Return to privileged EXEC mode.
Step 6
