i'm looking for help, because i need to configure an WLC2100, and i would like to know, if it's possible to connect directly the ap's to the wlc, or i will need a switch, to be between the wlc and ap's.
I say this because, when i connect an ap to an port (non ap-manager interface.), i can't obtain the configurations.
I only can work when i connect on the port that have the ap-manager interface.
I guess it's impossible to the wlc 2100 have more than 1 ap-manager interface assigned to the ports, according to the manual:
3-39 Cisco Wireless LAN Controller Configuration Guide OL-18911-01 Configuring Multiple AP-Manager Interfaces Note Only Cisco 5500 series and 4400 series standalone controllers support the use of multiple AP-manager interfaces.
When you create two or more AP-manager interfaces, each one is mapped to a different port (see Figure 3-15). The ports should be configured in sequential order such 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. Note AP-manager interfaces need not be on the same VLAN or IP subnet, and they may or may not be on the same VLAN or IP subnet as the management interface. However, Cisco recommends that you configure all AP-manager interfaces on the same VLAN or IP subnet. Note You must assign an AP-manager interface to each port on the controller. 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.
But this make me confused, because on wlc2100 we have 2 PoE ports, why that if we can't connect the ap's directly?
I would appreciate your answer as soon as possible,
