interface_nameAn interface to configure.

Enables DFS on the device. In DFS mode device selects the most interference-free frequency channel by scanning all available frequencies.

dfsradarEnables DFS with radar detection. After choosing the most "clear" frequency channel the device listens to radars that may work on the specified frequency. In case of detecting the radar it starts frequency selection process again.
dfsoffDisables DFS on the device.
domainAllows to limit the frequencies available for scanning by selecting a predefined frequency domain set by the license.

freq { auto |"frequency_list"}

Sets frequency range allowable to DFS function.

  • "frequency_list" – range value in "ХХХХ-ХХХХ" form.
  • "auto" allows DFS to use all frequencies supported by the device.
cot hh:mm

Allows to make rescanning and choosing the most optimal frequency for using on the daily basis in the defined time. The "off" parameter disables this function.

  • "hh:mm" sets the time in hours and minutes.

newchannel | renewchannel 

Allows to scan for the least noisy channel at the moment and set it as an operational:

  • "newchannel" if the current frequency channel is the best, the device will keep it as operational.
  • "renewchannel"  the device will change the frequency channel even if the current one is the best, moving to the next one.
showmapWhen InstantDFS is enabled, displays a table of interference at frequencies allowed for scanning.

scansec <seconds>

Sets the time that is spent on scanning each available frequency in seconds. By default is 3 second1 second.
rescan <minutes>

Allows to set the time interval in minutes after which the device repeates scanning and switches to a freer frequency, if possible. For models with the Instant DFS module, switching occurs without breaking the link.


Set the unit as "DFS Leader".

By using "mint" command enable the "Roaming Leader" mode. For more information about the roaming settings see "Frequency roaming" subsection of the "mint" command.

Code Block
mint rf5.0 roaming leader   

Enable DFS (if not already started).

Code Block
dfs rf5.0 dfsonly

Set the unit as "DFS Client".

Enable the "Roaming Profile" and start the roaming. For more information about the roaming settings see "Frequency roaming" subsection of the "mint" command.

Code Block
mint rf5.0 profile –freq auto
mint rf5.0 roaming enable

Let's set the automatic frequency selection on the device with iDFS function.

Code Block
dfs rf5.0 dfsonly
dfs rf5.0 freq auto

By default (if there is no "freq auto" command), the frequency selection will be performed within the frequency grid specified by the "rf rf5.0 grid" command. If a frequency range is specified instead of "freq auto", only those frequencies will be used.
