Introduction

Altitude 3500 Series Access Point Product Reference Guide

Rogue AP Detection Enhancement

The access point now has the option to scan for rogues over all channels on both of the access point’s

11a and 11bg radio bands. The switching of radio bands is based on a timer with no user intervention

required.

For information on configuring the access point for Rogue AP support, see “Configuring Rogue AP

Detection” on page 210.

RADIUS Time-Based Authentication

An external server maintains a users and groups database used by the access point for access

permissions. Various kinds of access policies can be applied to each group. Individual groups can be

configured with their own time-based access policy. Each group’s policy has a user defined interval

defining the days and hours access is permitted. Authentication requests for users belonging to the

group are honored only during these defined hourly intervals.

For more information on defining access point access policies by group, see “Defining User Access

Permissions by Group” on page 226.

QBSS Support

Each access point radio can be configured to optionally allow the access point to communicate channel

usage data to associated devices and define the beacon interval used for channel utilization

transmissions. The QBSS load represents the percentage of time the channel is in use by the access point

and the access point’s station count. This information is very helpful in assessing the access point’s

overall load on a channel, its availability for additional device associations and multi media traffic

support.

For information on enabling QBSS and defining the channel utilization transmission interval, see

“Configuring the 802.11a or 802.11b/g Radio” on page 154.

LLDP Support

Link Layer Discovery Protocol (LLDP) is a Layer 2 protocol (IEEE standard 802.1AB) used to determine

the capabilities of devices such as repeaters, bridges, access points, routers and wireless clients. LLDP

enables devices to advertise their capabilities and media-specific configurations. LLDP provides a

method of discovering and representing the physical network connections of a given network

management domain. The LLDP neighbor discovery protocol allows you to discover and maintain

accurate network topologies in a multi-vendor environment. LLDP transmits periodic advertisements

containing device information and media-specific configuration information to neighbors attached to the

same network.

For information on configuring the LLDP settings on devices, see “Configuring LLDP Settings” on

page 100.
