When you wish to convert a Cisco SWAN from Layer 3 to Layer 2 LWAPP Transport Mode using the
Cisco WCS User Interface, complete the following steps:
1. 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.
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.
CAUTION: This step is very important! If you change the Cisco SWAN From Layer 3
to Layer 2 while the Cisco Wireless LAN Controllers and Cisco 1000 Series lightweight
access points are on different subnets, they will be UNABLE TO COMMUNICATE with
each other after the conversion to Layer 2 mode.
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.
