New advanced features and multiple resolved cavities

Improvements

• Zero Wait Dynamic Frequency Selection - When an access point (AP) moves to Dynamic Frequency Selection (DFS) channel, a service outage can occur. This feature helps to avoid service outages in regulatory domains.

• Mesh Backhaul RRM Support - From this release onwards, RRM DCA runs on mesh backhaul, in the auto mode, when you configure the wireless mesh backhaul rrm auto-dca command. For APs that do not have dedicated (RHL) radios, DCA is triggered by running commands in the privilege EXEC mode. Mesh RRM DCA runs in the background for RHL radio enabled APs.

• RUM Report Throttling - For all topologies where the product instance initiates communication, the minimum reporting frequency is throttled to one day. This means the product instance does not send more than one RUM report a day.
