This illustration shows a wireless network with multiple access points.
Wireless end devices can roam between the access points to
communicate with the host and other end devices.
Figure 8. Multiple Access Points with Roaming End Devices
An end device initiates a roam when it attaches to a new access point. The
access point sends an attach message to the root access point, which in
turn forwards a detach message to the previous access point, allowing
each access point to update its forwarding database. Intermediate access
points monitor these exchanges and update their forwarding databases.
With the access point’s multichannel architecture, you can have more than
one access point within the same cell area to increase throughput and
provide redundancy. For more information, see “Using Dual Radio Access
Points for Redundancy” on page 37.
To install multiple access points with roaming end devices
1. Follow the instructions for installing a simple wireless network in “Using
One Access Point in a Simple Wireless Network” on page 22.
2. Configure the LAN ID. For help, see “Configuring the Spanning Tree
Parameters” on page 136.
3. Configure one of the access points to be a root access point. For help,
see “About the Primary LAN and the Root Access Point” on page 131.
4. If your network has a switch that is not IEEE 802.1d-compliant and is
located between access points, configure data link tunneling. For help,
see “About Ethernet Bridging/Data Link Tunneling” on page 134.
