Connect each Cisco 1000 Series lightweight access point to its final location in the network. 
Each Cisco 1000 Series lightweight access point connects to its Primary, Secondary, or Tertiary 
Cisco Wireless LAN Controller, downloads a copy of the latest Operating System code, and 
starts reporting its status to the Cisco Wireless LAN Controller. Note that this can take a few 
minutes for each Cisco 1000 Series lightweight access point.

You have completed the LWAPP Transport Mode conversion from Layer 2 to Layer 3. The ap-manager 
interface now controls all communications between Cisco Wireless LAN Controllers and Cisco 1000 
Series lightweight access points on different subnets. Continue with the 

Using the Cisco WCS User Interface

When you wish to convert a Cisco WLAN Solution from Layer 2 to Layer 3 LWAPP Transport Mode using 
the Cisco WCS User Interface, complete the following steps:

1.

To use the Cisco WLAN Solution in Layer 3 mode, you will need to create an AP Manager Inter-
face, which manages communications between each Cisco Wireless LAN Controller and its asso-
ciated Cisco 1000 Series lightweight access points. This AP Manager Interface will require a 
fixed IP address, which must be different from, but which must be on the same subnet as the 
Management Interface.

2.

MAKE SURE that all the Cisco Wireless LAN Controllers and Cisco 1000 Series lightweight access 
points are on the same subnet: that they are only connected through Layer 2 devices.

3.

In the Cisco WCS User Interface, select CONFIGURE/Access Points to navigate to the All 
Access Points page, and verify that the Primary, Secondary, and Tertiary Controller 
Names are correct for all Cisco 1000 Series lightweight access points. If you change the 
Primary, Secondary, or Tertiary Controller Names, click Apply to save the change to each Cisco 
1000 Series lightweight access point.

4.

Select CONFIG/Access Points to navigate to the All Access Points page, and MAKE SURE 
that the Cisco 1000 Series lightweight access points are associated with the Cisco Wireless LAN 
Controller before you continue with the next step.
If you do not complete this step, the Cisco 1000 Series lightweight access points may fail to 
associate with the Cisco Wireless LAN Controller after completing the conversion.

 This procedure will cause your Cisco 1000 Series lightweight access 

points to go offline until the Cisco Wireless LAN Controller reboots and the associated 
Cisco 1000 Series lightweight access points reassociate with the Cisco Wireless LAN 
Controller.

 Layer 3 Mode requires that all subnets that the Cisco Wireless LAN Controllers 

and are connected to include at least one DHCP server. When you have completed 
this procedure, the Cisco Wireless LAN Controller stores its IP address in its associ-
ated Cisco 1000 Series lightweight access points. When each Cisco 1000 Series 
lightweight access point is powered up, it obtains an IP address from the local DHCP 
server, and connects to its Primary, Secondary, or Tertiary Cisco Wireless LAN 
Controller.

 Layer 3 Mode requires that all subnets that contain Cisco Wireless LAN 

Controllers and Cisco 1000 Series lightweight access points are routable to each 
other.

 This step is very important! You must configure the Cisco Wireless LAN 

Controllers and associated Cisco 1000 Series lightweight access points to operate in 
Layer 3 mode BEFORE completing the conversion.
