5.4.4.3 Blacklist Information
The blacklisted table displays all the channels that are blacklisted.
Click Refresh, to view updated/refreshed blacklisted channels.
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.
Bad Link Threshold Applicable only to BSU.
The BSU decides to blacklist the operating channel based on Bad Link Threshold
parameter. If the number of Bad Links (Between BSU and SU) equals or exceeds the
configured Bad Link Threshold 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.
Parameter Description
Channel Number Indicates the channel that is blacklisted.
Reason Specifies the reason for blacklisting a channel.
Following are the reasons for blacklisting a channel:
1. Remote Radar: An SU/End Point B detects radar and informs BSU/End Point A
respectively.
2. Local Radar: The device detects the radar on its own.
3. Interference: BSU detects interference based on the retransmission threshold.
4. Unusable: For bandwidths more than 5 MHz, channels that are not usable because
they fall in the frequency range of other radar/manual blacklisted channels. For
example, if channel 110 is blacklisted, then channels 108, 109, 111, 112 will
become unusable for 20 MHz bandwidth.
5. Manual: A channel is manually blacklisted by the administrator.
Time Elapsed The time elapsed since the channel was blacklisted due to radar and interference. When
the channel is blacklisted due to the presence of radar and interference, it will be
blacklisted again after 30 minutes.
This parameter is applicable for radar and interference blacklisted channels only.
