8000 Series - Software Management Guide 100
• When DCS is enabled, the device computes the percentage of retransmissions (due to interference) for each link:
— If the link quality is bad, the channel is blacklisted for 30 minutes. ACS will scan all the non-blacklisted
channels and selects the channel with good link quality (least interference).
— If the link quality is above the threshold, the device continues to operate in the same channel.
• Periodically, the device monitors the current operating channel for link quality. If the link quality is found to be below
the threshold, the device stops transmitting in that channel and the channel is blacklisted.
• A channel in the blacklisted list is purged once the Non Occupancy Period (NOP) has elapsed for that channel.
• The BSU switches to the preferred channel once it is de-blacklisted.
:
• If DCS is enabled in BSU, ensure that ACS is enabled in SU.
• When DCS is enabled, Spectrum Analyzer scan cannot be performed.
To configure DCS parameters, navigate to ADVANCED CONFIGURATION > Wireless > Interface 1 > DFS/DCS. The DFS /
DCS/ Manual Blacklist Configuration screen appears.
