CAPWAP access point

Question

- Is there any instruction on how to provision the access point from CAPWAP?
- I have one access point that lost the configuration and can access to the console port only. How do I provision the AP back to the controller?
Thank you very much.

Answer 1

First, the Access-Point needs an IP Address. Assign IP address to the Access-Point using a DHCP Server configured on the router. Use the Option 43 with the AP Manager IP of the Wireless Controller. Here an Example:
Complete these steps in order to configure DHCP Option 43 for lightweight Cisco Aironet access points in the
embedded Cisco IOS DHCP server:
1. Enter configuration mode at the Cisco IOS CLI.
2. Create the DHCP pool, which includes the necessary parameters, such as the default router and server
name. This is an example DHCP scope:ip dhcp pool
network
default-router
dns-server
3. Add the Option 43 line with this syntax:option 43 hex
The hexadecimal string in step 3 is assembled as a sequence of the TLV values for the Option 43 suboption:
Type + Length + Value.
Type is always the suboption code 0xf1. Length is the number of controllermanagement IP addresses times 4 in hex.
Value is the IP address of the controller listed sequentially in hex.For example, suppose there are two controllers with management interface IP addresses, 192.168.10.5 and
192.168.10.20. The type is 0xf1. The length is 2 * 4 = 8 = 0x08. The IP addresses translate to c0a80a05
(192.168.10.5) and c0a80a14 (192.168.10.20). When the string is assembled, it yields
f108c0a80a05c0a80a14. The Cisco IOS command that is added to the DHCP scope is:
option 43 hex f108c0a80a05c0a80a14
