Radio Resource Management (RRM) Dynamic Channel Assignment (DCA) Support on Mesh Backhaul

Until the Cisco IOS XE 17.13.1 release, the RRM DCA optimized the root AP (RAP) backhaul radio channel of a mesh subtree by considering the noise, interference, load, and the RF parameter measurements only from the RAP.
From this release, the RRM DCA on Mesh Backhaul feature enables DCA to make better channel assignments for a mesh subtree, by having continuous measurements and inputs from the whole mesh tree required to run DCA.

The following command is introduced:

• show wireless mesh rrm dca changed
