Note
When you downgrade from 5.1.163.0 to 4.2.61.0 or an earlier release, the LWAPP mode may or may not
change from Layer 3 to Layer 2, depending on whether the configuration was saved in the earlier image.
If the LWAPP mode changes, access points may not join the controller, and you must manually reset the
controller to Layer 3 to resolve this problem.
