Joining CISCO AP 1041N to a WLC 2500 Series

[ranimbouraoui]

Hello,

I have a problem joining 10 CISCO AP's 1041N to a WLC 2500 Series.

I have the following network architecture,

A Windows Server 2012 R2 (DC, DHCP and DNS Server) connected to CISCO 2960-X Series (This switch is connected to 2 other switches, same model), the 10 AP's and the WLC are connected to the same Switch, as I have 3 NIC's on the Server I am using one for Internet from the Firewall and the three others are teamed together and connected to the Switch.

I tried the following methods:

- I used the Option 43 on the DHCP Server: Not Working

- I added 2 DNS Entries (cisco-capwap-controller.mydomain and cisco-lwapp-controller.mydomain) : not working

- UDP Ports for CAPWAP and LPWAP are enabled on the Windows Firewall : not working

My WLC is set in Master Controller Mode, I can see all the AP's in the DHCP Server with their IP's affected by the server and the WLC as well, and they can ping on each other.

In addition, on the WLC, I have one interface (management) with VLAN ID 0, the Server have (Default VLAN) no ID affected, the Switch have VLAN ID 1 (Default), and I tried to change all of them to the same VLAN ID 1 (Server, Switch, WLC) in that case the server is not able to communicate with all of them and DHCP is not working.

Thank you for your help.

Try to configure the IP address of the WLC static on the APs: capwap ap controller ip address x.x.x.x

Do you have enaugh AP licenses on the controller ?

[ranimbouraoui]

Thanks for the answer, I have enough licenses for the WLC (10 in total)

I tried the command and I got the following message

ap#capwap ap controller ip address  192.168.1.7
    ^
% Invalid input detected at '^' marker.

ap#

Oh, your APs are in autonomous mode, thats why they cannot join to the WLC. You have to convert them to lightweight! Here is a good guide - http://mrncciew.com/2012/10/20/lightweight-to-autonomous-conversion/

Everything is up and running, I installed the image on the AP's and they are able now to join the controller using Option 43.

Thank you for your help.

My WLC have the IP 192.168.1.7

The AP's have the range starting from 192.168.1.8 to 192.168.1.17
