Chapter 4 Configuring Controller Settings
Configuring 802.11 Bands
config {802.11a | 802.11b} fragmentation threshold
where threshold is a value between 256 and 2346 bytes (inclusive). Specify a low number for areas where
communication is poor or where there is a great deal of radio interference.
Step 5 Make access points advertise their channel and transmit power level in beacons and probe responses by
entering this command:
config {802.11a | 802.11b} dtpc {enable | disable}
The default value is enabled. Client devices using dynamic transmit power control (DTPC) receive the
channel and power level information from the access points and adjust their settings automatically. For
example, a client device used primarily in Japan could rely on DTPC to adjust its channel and power
settings automatically when it travels to Italy and joins a network there.
Note On access points that run Cisco IOS software, this feature is called world mode.
Step 6 Specify the rates at which data can be transmitted between the controller and the client by entering this
command:
config {802.11a | 802.11b} rate {disabled | mandatory | supported} rate
where
• disabled—Clients specify the data rates used for communication.
• mandatory—Clients support this data rate in order to associate to an access point on the controller.
• supported—Any associated clients that support this data rate may communicate with the access
point using that rate. However, the clients are not required to be able to use this rate in order to
associate.
• rate—The rate at which data is transmitted:
– 6, 9, 12, 18, 24, 36, 48, and 54 Mbps (802.11a)
– 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, or 54 Mbps (802.11b/g)
Step 7 Enable the 802.11a band by entering this command:
config 802.11a enable network
The default value is enabled.
Step 8 Enable the 802.11b band by entering this command:
config 802.11b enable network
The default value is enabled.
Step 9 Enable or disable 802.11g network support by entering this command:
config 802.11b 11gSupport {enable | disable}
The default value is enabled. You can use this command only if the 802.11b band is enabled. If you
disable this feature, the 802.11b band is enabled without 802.11g support.
Step 10 Save your changes by entering this command:
save config
Step 11 View the configuration settings for the 802.11a or 802.11b/g band by entering this command:
show {802.11a | 802.11b}
Information similar to the following appears:
