This document does not cover the steps involved in converting autonomous APs to Lightweight Access Point Protocol (LWAPP) APs such that they can be controlled by the 4400 WLC. Please contact Cisco's Customer Support at www.cisco.com for instructions on this procedure. Once the APs are converted, this document can be used to provision LWAPP APs.

Subnet roaming was successfully tested, although it is not represented in the network configuration diagram, nor is it covered in the subsequent configuration steps contained in this document. It is important to note that the SpectraLink Wireless Telephones cannot roam across subnets without the creation of a tunnel between two Cisco WLCs. Please consult the Cisco documentation in order to configure these tunneling mechanisms.

Access Point Capacity and Positioning

Please refer to the Polycom Deploying Enterprise-Grade Wi-Fi Telephony

white paper. This document covers the security, coverage, capacity and QoS considerations necessary for ensuring excellent voice quality with enterprise Wi-Fi networks.

For more detailed information on wireless LAN layout, network infrastructure, QoS, security and subnets, please see the

Guide for Deploying SpectraLink 8020/8030 Wireless Telephones. This

document identifies issues and solutions based on Polycom’s extensive experience in enterprise-class Wi-Fi telephony, and provides recommendations for ensuring that a network environment is adequately optimized for use with SpectraLink 8020/8030 Wireless Telephones.

Configuration Guide

Configuring a New Controller Starting from Factory Defaults

1. Initial provisioning of the controller is done via the command line

interface (CLI). Connect a null modem serial cable between the console port of the controller and the serial port of a PC.

2. Open a terminal program, such as Hyper Terminal, and configure

the port settings to

3. Power-on the controller. Status of the controller’s boot process

will appear as the controller is powering up. Once the controller is running, it will prompt you to run the

5. Once the controller has been configured via the Startup

the remaining configuration can be configured through the switch’s Web interface using a Web browser (Cisco recommends using MS IE 6.0+).

6. If necessary, the controller can be reset to factory defaults. To reset

the

WLC to factory default, you must reboot, then type

Recover-config at the CLI. This only works before the first time

a user logs in via the console.
