Common Radio Module Configuration Commands
Dynamic
Frequency
Selection
show {arm<n>|brm<n>} dfs
set {arm<n>|brm<n>} dfs {enabled|disabled}
These commands let you manage the Dynamic Frequency Selection (DFS)
feature. The
set
command is only available if you are logged in as
root
.
These commands apply only if your unit contains a radio with part numbers
B2CC034AA, B2CC034AB or B2CC033AA. Use the
/system/show phyinv
command to display the radio’s part number.
Dynamic Frequency Selection (DFS) is a regulatory requirement in some
jurisdictions. It is normally set automatically when specifying the country of
operation.
The
show
command displays various parameters associated with DFS. The
default value of the secondary channel is 0, instructing DFS to operate as if the
secondary channel is the same as the primary channel.
The
set
command suppresses any use of DFS by the
set country
<country_code>
command. When disabled with this command, DFS remains
disabled for all radio channels until re-enabled by this command.
CAUTION!
Improper setting of DFS may exceed regulatory requirements and void the
operator’s right to operate the radio equipment.
For details on specify the country of operation, see:
