determines the scan interval, between
60–86400
seconds (the
default is
300
). Lonely Node operates under the following
conditions:
Channel Lock is disabled
Channel Scanning is enabled
A WDS BSS is enabled
No FP Mesh peer connections exist on the bridging radio
The same settings are output interactively regardless of the
specified radio. The possible values for each setting vary
based on the features supported by the Mesh Point you are
administering.
Alternatively, you can use the
set radio command with valid
switches and arguments to change the radio settings:
# set radio -name radio1|radio2 -adminstate enable|disable
-band 802.11g|802.11nght20|802.11nght40plus|802.11nght40minus|802.11a|802.11naht20|

The sample output for the show radio command (at the
beginning of this section) shows the default radio settings.
You must be logged on to an

3.4.8 DFS, TDWR, and Channel Exclusion
Channels in the 5 GHz 801.11a frequency band can be
excluded from selection by several means and for various
reasons.
3.4.8.1 Dynamic Frequency Selection
NOTE: Radar
events occurring
while on a DFS channel
while ChannelLock is
enabled cause the radio
to be disabled, rather
than to select an alter-
nate channel. (See Sec-
tion 3.4.7.)
Most regulatory domains, including the Mesh Point’s default
FCC domain, require that certain channels in the 5 GHz
801.11a frequency band operate as DFS (Dynamic Frequency
Selection) channels.
DFS is a radar (radio detection and ranging) avoidance
protocol. Devices transmitting on a DFS channel must detect
approaching radar on the channel, vacate the channel within
10 seconds of doing so, and stay off the channel for a minimum
of 30 minutes thereafter.
Radios using the 2.4 GHz 802.11g frequency band or the
4.4 GHz band are not subject to DFS.
