Disabling Slot Bias

To disable slot bias so that the APs can be stable on slot 1, enter the config mesh slot-bias disable command.
The slot bias is enabled by default.
Note
Usage Guidelines
Follow these guidelines for the config mesh slot-bias disable command:
• The config mesh slot-bias disable command is a global command and is applicable to all 1524SB APs
associated with the same controller.
• Slot bias is applicable only when both slot 1 and slot 2 are usable. If a slot radio does not have a channel
that is available because of dynamic frequency selection (DFS), the other slot takes up both the uplink
and downlink roles.
• If slot 2 is not available because of hardware issues, slot bias functions normally. Take corrective action
by disabling the slot bias or fixing the antenna.
• A 15-minute timer is initiated (slot bias) only when slot 1 and slot 2 are usable (have channels to operate).
• The 15-minute timer is not initiated if slot 2 cannot find any channels because of DFS, which results in
slot 1 taking over the uplink and the downlink.
• Slot 2 takes over slot 1 if slot 1 does not have any channels to operate because of DFS.
• If slot 2 has a hardware failure, then slot bias is initiated, and slot 1 is selected for uplinking.
• Disabling slot bias enables you to take preventive action for a smooth operation.
