Configuring the Maximum Data Retries
Configuring the Maximum Data Retries
The maximum data retries setting determines the number of attempts that the wireless device makes to
send a packet before it drops the packet. The default setting is 32.
To configure the maximum data retries, follow these steps, beginning in privileged EXEC mode.
SUMMARY STEPS
1. configure terminal
2. interface dot11radio {0| 1}
3. packet retries value
4. end
5. copy running-config startup-config
DETAILED STEPS
Use the no form of the packet retries command to reset the setting to the default.
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 2346 bytes.
To configure the fragmentation threshold, follow these steps, beginning in privileged EXEC mode.
SUMMARY STEPS
1. configure terminal
2. interface dot11radio {0| 1}
3. fragment-threshold value
4. end
5. copy running-config startup-config
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
802.11g/n 2.4-GHz radio is radio 0.
The 802.11n 5-GHz radio is radio 1.
Step 3
packet retries value Sets the maximum data retries. Enter a setting from 1 to 128.
Step 4
end Returns to privileged EXEC mode.
Step 5
copy running-config startup-config (Optional) Saves your entries in the configuration file.
