OL-7426-02
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 Product Guide

Using the Cisco WCS User InterfaceUsing the Cisco WCS User Interface
When you wish to convert a Cisco SWAN from Layer 2 to Layer 3 LWAPP Transport Mode using the
Cisco WCS User Interface Interface, complete the following steps:
1. To use the Cisco SWAN in Layer 3 mode, you will need to create an AP Manager Interface,
which manages communications between each Cisco Wireless LAN Controller and its associated
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 Manage-
ment Interface.
2. Be 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. 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 be 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.
5. Change the LWAPP Transport Mode from Layer 2 to Layer 3:
CAUTION: 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.
Note: 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.
Note: 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.
CAUTION: 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.
