Configuring a 4400 Series Controller to Support More Than 48 Access Points
Figure 3-14
Before implementing multiple AP-manager interfaces, you should consider how they would impact your
controller's port redundancy.
Examples:
1. The 4402-50 controller supports a maximum of 50 access points and has two ports. To support the
maximum number of access points, you would need to create two AP-manager interfaces (see

The 4404-100 controller supports up to 100 access points and has four ports. To support the

maximum number of access points, you would need to create three (or more) AP-manager interfaces

access points' state, and the access points must reboot to reestablish communication with the
controller using the normal controller join process. The controller no longer includes the failed
AP-manager interface in the CAPWAP or LWAPP discovery responses. The access points then
rejoin the controller and are load-balanced among the available AP-manager interfaces.
