Layer 3 mode enables an AP to join a WLC either within the same subnet or across subnets boundaries connected by a router.Д¬onfigure Primary/Secondary/Tertiary WLCs using the command:ДЄp#capwap ap -base

#Capwap ap controller ip address how to

For information on how to statically configure controller information using the AP CLI, use the following command: Layer 3 : You can statically configure the information necessary to join a controller via the console port and the APs CLI. In order to ensure that the LAPs only join controllers locally, Cisco cannot use a DNS entry and must use DHCP option 43 information to tell the LAPs what the management IP address of their local controller is.ДЇinally, the static configuration is used for a network that does not have a DHCP server. For example, Cisco owns buildings in Europe, Australia, and the United States. This method is used by large enterprises that have a single DNS suffix. Or, if the company has multiple DNS suffixes and the controllers are segregated by suffix.ДHCP option 43 is used by large companies to localize the information via the DHCP. This method should be used by companies that have all of their controllers in a single location and own a local DNS server. This allows the LAP to discover multiple controllers. You can have multiple entries of the same DNS name. The next easiest method of deployment is to use a DNS entry with DHCP. This method should be used for companies that have a small network and do not own a local DNS server. It will remember the controller.ДЇrom this above list, the easiest method to use for deployment is to have the LAPs on the same subnet as the management interface of the controller and allow the LAPs Layer 3 broadcast to find the controller. The previously known controller will come into the picture when the AP was previously connected to the WLC and then just reboots. The first 3 process is the dynamic process and the 4th method is the static process

Hard Code primary /secondary /tertiary controller DHCP options 43/60 -If the Ap uses DHCP for its IP the DHCP address can send in addition to the IP address of the WLAN.Д¤. Note:В If you use CAPWAP, make sure that there is a DNS entry forВ the cisco-capwap-controller.ДЈ. DNS entry forВ cisco-capwap-controllerВ (good for local businesses - can also be used to find where brand new APs join) Layer 3 broadcast-Broadcast-Once the AP gets the IP it sends the broadcast packet to all 255.255.255.255 with UDP port 5446.Дў. Since CAPWAP does not support L2 discovery so I am not mentioning that method in the AP controller discovery.ДЎ. (After getting an IP address, to join to the WLC, the LAP needs to know what all are those WLCs to which it can join).The purpose of the Discovery process is to build the list of the wireless LAN controller to possibly joined by the AP. Every device on a network needs to have an IP address, and a LAP is no exception. So the discovery process began when the access point boots up and gets an IP address. I will first discuss CAPWAP and later LWAP. Few wireless devices like Ruckus Wireless use LWAP protocol for the communication between the controller and the AP and Cisco now use CAPWAP for the communication between the AP and the controller. The discovery and join process does differ between LWAPP and CAPWAP. The join process is essentially the AP joining the Wireless LAN Controller (WLC). The discovery is just that-the AP discovering and validating that it is indeed talking to a controller. What does this mean in terms of troubleshooting? It is vital that you understand the discovery process because there could be multiple networks-large complex networks at that. The point is that the port that you plug the AP into might be thousands of miles away from the controller that it is supposed to join. This only happens if you have everything configured correctly. You can take an AP out of the box and literally plug it into any port on your network and the AP will join the controller. One of the major selling points of the AP and Controller design product is its scalability. If you understand how the discovery and join process works, your job will be much easier when you have to troubleshoot it. Registration is the first step in getting your wireless network up and running. So today we will discuss how the out of the box AP joins the controller in the network.ДЄccess point (AP)В registration consists of a discovery and joins process. As we have already discussed the LWAP and CAPWAP protocol in my previous article.
