Management Options
You can use the wireless device management system through the following interfaces:
•
The Cisco IOS command-line interface (CLI), which you use through a console port or Telnet
session. Use the interface dot11radio global configuration command to place the wireless device
into the radio configuration mode. Most of the examples in this manual are taken from the CLI.

Roaming Client Devices
If you have more than one wireless device in your wireless LAN, wireless client devices can roam
seamlessly from one wireless device to another. The roaming functionality is based on signal quality, not
proximity. When signal quality drops from a client, it roams to another access point.

Wireless LAN users are sometimes concerned when a client device stays associated to a distant access
point instead of roaming to a closer access point. However, if a client signal to a distant access point
remains strong and the signal quality is high, the client will not roam to a closer access point. Checking
constantly for closer access points would be inefficient, and the extra radio traffic would slow throughput
on the wireless LAN.

Using Cisco Centralized Key Management (CCKM) or 802.11r, with a device providing wireless
distribution system (WDS), client devices can roam from one access point to another so quickly that
there is no perceptible delay in voice or other time-sensitive applications.

Network Configuration Examples
This section describes the role of an access point in common wireless network configurations. The
access point default configuration is as a root unit connected to a wired LAN or as the central unit in an
all-wireless network. Access points can also be configured as repeater access points, bridges, and
workgroup bridges. These roles require specific configurations.
