Controller Based WLANs

How to configure AP 224/225 to use link aggregation to use both its uplink.

Environment :Controller ============= Switch (LACP)=============(LACP)AP 225 This feature is introduced from AOS 6.3.1.

 

AP 225 can use both ports for uplink. This feature is introduced from 6.3.1.
 
For this, Controller needs to have one more ip address defined in ap system profile (ideally LMS IP +1), called GRE Striping IP.
