•
Pre-stage configuration for LWAPP-enabled access points—Simplifies the deployment of
LWAPP-enabled access points in remote locations by adding a new set of access point CLI
commands to the recovery IOS image. The static IP address, netmask, default gateway, and primary
controller IP address may now be configured on the IOS access point. Configuring the primary
controller IP address helps the access point to discover and register a specific controller over the
WAN links. In a deployment scenario where a DHCP server is not available in remote locations, the
access point CLI commands may be used to configure the static IP address and the initial controller
information.
