14. 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 Product Guide.
Using the Cisco WCS User InterfaceUsing 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.
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.
