Cisco Cisco 5520 Wireless Controller 기술 참조

Existing APs must be upgraded to 7.5 software before joining a virtual controller.

For Cisco 600 Series OEAP to associate with Cisco Virtual Wireless LAN Controller, follow these 
steps:

Configure the OEAP to associate with a physical controller that is using 7.5 or a later release and 
download the corresponding AP image.

Configure the OEAP so that the OEAP does not associate with the physical controller again; for 
example, you can implement an ACL in the network to block CAPWAP between the OEAP and the 
physical controller.

Configure the OEAP to associate with the Cisco Virtual Wireless LAN Controller.

The Virtual Controller in release 7.5 uses Self Signed Certificates (SSC) as against the Manufacturing 
Installed Certificates (MIC) in the traditional controller. The AP will be able to validate the SSC 
certificate provided by the virtual controller before joining. See AP Considerations in the following link:

The information in this document was created from the devices in a specific lab environment. All of the 
devices used in this document started with a cleared (default) configuration. If your network is live, make 
sure that you understand the potential impact of any command.

In order to properly implement and test the Cisco vWLC, a minimal network setup is required, similar 
to the diagram shown in this section. You need to simulate a location with a FlexConnect AP in a 
centrally switched deployment, and/or with the addition of local and remote sites with local DHCP 
(better if there is also a DNS and local access to Internet).
