The
secondary
parameter applies to any radio supplying Dynamic Frequency
Selection (DFS), a regulatory requirement in some jurisdictions. The
secondary
parameter sets an optional secondary channel for use with DFS. The default
value is 0, instructing DFS to operate as if the secondary channel is the same as
the primary channel. If you change the channel number from the default value
and if you do not specify a secondary channel, then your secondary channel is
set to be the same as your primary channel. DFS behaves the same way
regardless of whether your secondary channel is the same as the primary
channel or whether your secondary channel is 0. Refer to your RF plan and site
survey to determine if you need to set a secondary channel other than 0 or
your primary channel.
The
channel-bandwidth
parameter sets the bandwidth of the channel you want
to use. The specified bandwidth is in MHz for all radios except the WCSv1, and
in kHz for the WCSv1.
The
auto
parameter causes the radio to search for surrounding APs. It then
selects channel settings based on the result of that search. The
re-scan-channel
command causes the radio to perform another search.

Antenna Gain
/interface/wifi-<n>-<m>/set antenna gain <gain>
[port {dedicated|shared}]
This command let you specify the gain of the antenna installed with your unit.
Use the
show available-config-options
command to display valid gain values (in
dBi). The displayed values vary depending on the country of operation and the
channel in use.
You must set the
<gain>
parameter to match the gain of the antenna installed
in your unit. For all countries except Korea, the default access antenna gain is
8 dBi. For Korea, the default access antenna gain is 6 dBi.
CAUTION!
Improper setting of channel, antenna gain and transmit power may exceed
regulatory requirements and void the operator’s right to operate the radio
equipment. Refer to the
BelAir Radio Transmit Power Tables
to determine valid
combinations of channel, antenna gain and transmit power for your country.
If your unit includes a DRU, its 5 GHz radio offers two sets of ports to connect
antennas. If you use single-band (5 GHz) antennas, set the
port
parameter to
