4/1/05 Converting a Cisco SWAN from Layer 2 to Layer 3 Mode
OL-7426-02
Converting a Cisco SWAN from Layer 2 to Layer 3 ModeConverting a Cisco SWAN from Layer 2 to Layer 3 Mode
When you wish to convert a Cisco SWAN from Layer 2 to Layer 3 Mode, use one of the following
procedures:
• Using the Web User Interface
• Using the Cisco WCS User Interface
Using the Web User InterfaceUsing the Web User Interface
When you wish to convert a Cisco SWAN from Layer 2 to Layer 3 LWAPP Transport Mode using the Web
User Interface, complete the following steps:
1. To use the Cisco SWAN in Layer 3 mode, you must create an AP Manager Interface, which man-
ages 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 the Management Interface IP address, but which can be
on the same subnet as the Management 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. Verify that the Cisco 1000 Series lightweight access points are assigned to the desired Cisco
Wireless LAN Controller. If you do not complete this step, the Cisco 1000 Series lightweight
access points will fail to associate with the Cisco Wireless LAN Controller after completing the
conversion.
A. Select WIRELESS/Cisco APs to navigate to the Cisco APs page, and click Detail to
have the Web User Interface display the Cisco APs > Details page.
B. On the Cisco APs > Details page for each Cisco 1000 Series lightweight access point,
verify that the Primary, Secondary, and Tertiary Controller Names are correct. If
you change the Primary, Secondary, or Tertiary Controller Names, click Apply to save
the change to the Cisco 1000 Series lightweight access point.
4. Select WIRELESS/Cisco APs to navigate to the Cisco APs page, and be sure that all the
Cisco 1000 Series lightweight access points are listed before you continue with the next step.
CAUTION: This procedure causes 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 used by the Cisco Wireless LAN Control-
lers include at least one DHCP server. When you have completed this procedure, the
Cisco Wireless LAN Controller stores its IP address in its associated 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.
