Description
Use the
channel
band-width
command to specify the channel bandwidth of the 802.11n radio.
Use the
undo channel
band-width
command to restore the default.
Support for the command depends on the device model.
By default, the channel bandwidth of the 802.11an radio is 40 MHz, and that of the 802.11gn radio is 20
MHz.
This command is only effective on 802.11n radios. If you change the radio type of an 802.11n radio, the
default setting for this function of the new radio type will be restored.
Currently, an 802.11a/n or 802.11g/n radio working in 5 GHz or 2.4 GHz bands selects an available 40
MHz channel as the operating channel. If no 40 MHz channel is available, it selects a 20 MHz channel.
Examples
# Configure the channel bandwidth of the radio as 20 MHz.
