Cisco Cisco 2000 Series Wireless LAN Controller Release Notes

This section describes important information about the controllers and access points.

The 2106 controller’s Status LED and AP LED do not flash amber when software is being uploaded to 
the controller or downloaded to an access point, respectively.

Some versions of the Cisco 2106 Wireless LAN Controller Quick Start Guide may incorrectly state that 
these LEDs flash amber during a software upload or download.

After you perform these functions on the controller, you must reboot the controller in order for them to 
take effect:

Switch between Layer 2 and Layer 3 LWAPP mode

Enable or disable link aggregation (LAG)

Enable a feature that is dependent on certificates (such as HTTPS and web authentication)

Enable or disable the mobility protocol port using this CLI command:

config mobility secure-mode {enable | disable}

If you wish to reset the configuration to factory defaults on a 2006 controller, perform one of the 
following:

From the controller GUI, click Commands > Reset to Factory Default > Reset.

From the controller CLI (after system bootup and login), enter clear config. Then after the 
configuration has been cleared, enter reset system without saving the current configuration.

From the controller console (after system bootup), enter Recover-Config from the User Name 
prompt.

Do not attempt to reset the controller’s configuration by choosing Option 5, Clear Config from the boot 
menu unless you have successfully upgraded to the _ER.aes image on Cisco.com. See CSCsg18356 in 
the 

 for more details.
