Information About Multiple AP-Manager Interfaces
When you create two or more AP-manager interfaces, each one is mapped to a different port. We recommend that you configure the ports in sequential order so that AP-manager interface 2 is on port 2, AP-manager interface 3 is on port 3, and AP-manager interface 4 is on port 4.
Before an access point joins a controller, it sends out a discovery request. From the discovery response that it receives, the access point can tell the number of AP-manager interfaces on the controller and the number of access points on each AP-manager interface. The access point generally joins the AP-manager with the least number of access points. In this way, the access point load is dynamically distributed across the multiple AP-manager interfaces.
Note |
Access points may not be distributed completely evenly across all of the AP-manager interfaces, but a certain level of load balancing occurs. |
Multiple AP-Manager interfaces are also supported in non-LAG setups, only if you are not going to configure the controller for either LAG or IPv6.
