Introduction
The DHCP client automatically sends a DHCP request at an interval specified by the DHCP server to
renew the IP address lease as long as the access point is running (this parameter is programmed at
the DHCP server). For example: Windows 2000 servers typically are set for 3 days.

1.2.23 Multi-Function LEDs

An AP-5131 model access point has seven LED indicators. Four LEDs exist on the top of the and are
visible from wall, ceiling and table-top orientations. Three of these four LEDs are single color activity
LEDs, and one is a multi-function red and white status LED. Two LEDs exist on the rear of the access
point and are viewable using a single (customer installed) extended light pipe, adjusted as required
to suit above the ceiling installations. An AP-5181 model access point houses four LEDs on the
bottom/back side of the unit.
For detailed information on the access point LEDs and their functionality, see AP-5131 LED Indicators
on page 2-23 or AP-5181 LED Indicators on page 2-29.

1.2.24 Mesh Networking

Utilize the new mesh networking functionality to allow the access point to function as a bridge to
connect two Ethernet networks or as a repeater to extend your network's coverage area without
additional cabling. Mesh networking is configurable in two modes. It can be set in a wireless client
bridge mode and/or a wireless base bridge mode (which accepts connections from client bridges).
These two modes are not mutually exclusive.
In client bridge mode, the access point scans to find other access points using the selected WLAN's
ESSID. The access point must go through the association and authentication process to establish a
wireless connection. The mesh networking association process is identical to the access point's MU
association process. Once the association/authentication process is complete, the wireless client
adds the connection as a port on its bridge module. This causes the access point (in client bridge
mode) to begin forwarding configuration packets to the base bridge. An access point in base bridge
mode allows the access point radio to accept client bridge connections.
The two bridges communicate using the Spanning Tree Protocol (STP). The spanning tree determines
the path to the root and detects if the current connection is part of a network loop with another
connection. Once the spanning tree converges, both access points begin learning which destinations
reside on which side of the network. This allows them to forward traffic intelligently.
After the access point (in client bridge mode) establishes at least one wireless connection, it will
begin beaconing and accepting wireless connections (if configured to support mobile users). If the
