Unable to register AP to WLC

[SATISH KATTIKA]

Hi Floks, 

I am trying to register AP to WLC , But it is not registering and more basic problem i found on the switch is  ,AP mac address is assigned with 2 IP address, .

I suspect 2 Ip address assignment for single mac address is creating the problem , Does any body have some idea why it is assging 2 IP address.

Could you please share your thoughts on this. 

Cheer's 

Satish.

Hi,

May be your AP had static IP .

If you have console access to this AP, you can try this

LWAP#debug capwap console cli
This command is meant only for debugging/troubleshooting 
Any configuration change may result in different
behavior from centralized configuration. 
CAPWAP console CLI allow/disallow debugging is on

LWAP#erase /all nvram: 
Erasing the nvram filesystem will remove all files! Continue? [confirm]
[OK]
Erase of nvram: complete

LWAP#reload
Proceed with reload? [confirm]
Writing out the event log to nvram.

Attache the console output still you unable to solve this with this steps.

 Resetting to Default Settings Using the CLI

Caution You should never delete any of the system files prior to resetting defaults or reloading software.

If you want to reset the access point to its default settings and a static IP address, use the write erase or erase /all nvram command. If you want to erase everything including the static IP address, in addition to the above commands, use the erase and erase boot static-ipaddr static-ipmask command.

From the privileged EXEC mode, you can reset the access point/bridge configuration to factory default values using the CLI by following these steps:

Step 1 Enter erase nvram: to erase all NVRAM files including the startup configuration.

Note The erase nvram command does not erase a static IP address.

Step 2 Follow the step below to erase a static IP address and subnet mask. Otherwise, go to step 3.

a. Enter write default-config.

Step 3 Enter Y when the following CLI message displays: Erasing the nvram filesystem will remove all configuration files! Continue? [confirm].

Step 4 Enter reload when the following CLI message displays: Erase of nvram: complete. This command reloads the operating system.

Step 5 Enter Y when the following CLI message displays: Proceed with reload? [confirm].

Caution Do not interrupt the boot process to avoid damaging the configuration file. Wait until the access point/bridge Install Mode LED begins to blink green before continuing with CLI configuration changes. You can also see the following CLI message when the load process has finished: Line protocal on Interface Dot11Radio0, changed state to up.

Step 6 After the access point/bridge reboots, you can reconfigure the access point by using the Web-browser interface if you previously assigned a static IP address, or the CLI if you did not.

The Access point is configured with the factory default values including the IP address (set to receive an IP address using DHCP). To obtain the access point/bridge's new IP address, you can use the show interface bvi1 CLI command.
