Spectrum Management uses this margin when making a
channel hop decision. If the interference level of the target
channel is lower than that of the active channel by at least the
Hopping Margin, the link will hop to the target channel. The
default setting is 3 dB in non-radar regions, or 10 dB in radar
regions.
Only displayed in non-radar regions when i-DFS is enabled.
The default configuration of symmetric operation constrains
the link to operate symmetrically, using the same transmit
and receive channels. When in symmetric mode the slave unit
will always follow the master. If the master moves to a new
channel the slave will hop to the same channel. When the
Point-to-Point link is configured as an asymmetric link both
the master and slave are free to select the best channel from
their own set of local interference metrics.
Only displayed in radar regions. The options are 'DFS' and
'DFS with i-DFS'.
The Spectrum Management algorithm evaluates the metrics
every 'Hopping Period' seconds (180 seconds by default)
looking for a channel with lower levels of interference. If a
better channel is located, Spectrum Management performs an
automated channel hop. If SNMP or SMTP alerts are enabled
an SNMP TRAP or an email alert is sent warning the system
administrator of the channel change.
This is used to record the number of channel hops. The
number in the (+) brackets indicates the number of channel
changes since the last screen refresh.
