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

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.

Connecting to the Controller via a Browser
1. Connect to the WLC by pointing your internet browser to the
URL: https<IP_Addr> (where <IP_Addr> is the IP address of the
management interface of the WLC).

Connecting APs
As the APs are connected to the network, they should automatically
find the controller via the LWAPP discovery algorithms. The
Dynamic Host Configuration Protocol (DHCP) server will assign each
AP an IP address.
You can configure a DHCP server to run on a remote PC for a small
deployment. However, for large-scale deployments, an enterprisegrade DHCP server must be used.

configure the DHCP server internally on the controller to hand out
leases to the connected clients. (Note: The WLC’s DHCP server does
not lease addresses to the AP.) The instructions for doing so are
included at the end of this document.
