Given below is the table which explains Dynamic Channel Selection (DCS) parameters and the method to configure the
configurable parameter(s):

After configuring the required parameters, click OK and then COMMIT.

Click Refresh, to view updated / refreshed blacklisted frequency range.

Manual Blacklisting enables you to manually blacklist one or more channels in terms of frequency range for the following
reasons: radar, interference, and to reduce the number of channels to scan. The Manual Blacklist screen appears as shown
below.

Dynamic Channel 
Selection (DCS) Status

This parameter is used to enable DCS on the device. By default, DCS is disabled. To enable, 
select Enable and Click OK.

Retransmission 
Threshold

This parameter enables to configure the retransmission threshold percentage on the 
device. The device computes percentage of retransmission for each link and compares 
with the configured threshold. If the retransmission percentage is greater than the user 
configured retransmission threshold, the link is considered as bad link. 

By default, the retransmission percentage is set to 50.

SUs Reporting 
Interference

Applicable only to BSU.

The BSU decides to blacklist the operating channel based on the value configured for this 
parameter. If the number of SUs reporting interference (Between BSU and SU) equals or 
exceeds the configured value of this parameter then the channel is blacklisted. Else, it 
continues to operate in the same channel.

By default, Bad Link Threshold value is set to 1.
