Chapter 3 - Layer 2 Command Set - PHY and MAC Dfs (Dynamic Frequency Selection)
Alvarion BreezeNET B130/B300 GigE 100 Operational User Manual
- dfs "interface_name" scansec <seconds> - sets the time that is spent on
scanning each available frequency in seconds. By default: 6 seconds.
DFS default operational characteristics:
 Channel occupation time: 24 hours
 Scanned time for DFS leader: 6 seconds for each available frequency
 Listening to the Radar on the chosen frequency: 1 minute
3.8.1 DFS Leader/Client Configuration
DFS Leader is a unit that process actual frequency selection and radar detection
functions. DFS Client is a unit that does not choose the frequency itself but
follows DFS Leader's frequency settings.
For example, in PTP link one unit should be configured as DFS Leader and
another one as DFS Client. It is strongly recommended to set as a Leader the unit
that is working in worthier interference conditions.
To set a unit as a "DFS Leader" (example):
1 Configure it as a master:
mint rf5.0 type master
Please refer to the "MINT" chapter for detailed description.
2 Start DFS (if not already started).
dfs rf5.0 dfsonly
The unit will perform DFS functions and send the chosen frequency information
to the "DFS Client" devices.
CAUTION
The accuracy of the "dfs cot" function is about 5 minutes
CAUTION
DFS client is searching the DFS leader's frequency in random order.
