Overview of the Summit WM series switch, access points, and WLAN switch software solution

Summit WM Series WLAN Switch and Altitude Access Point Software Version 4.1 User Guide

If a Summit WM series switch fails, all of its associated Altitude APs can automatically switch over to

another Summit WM series switch that has been defined as the secondary or backup Summit WM series

switch. If the AP reboots, the original Summit WM series switch is restored. The original Summit WM

series switch is restored if it is active. However, active APs will continue to be attached to the failover

controller until the administrator releases them back to the original home controller.

Quality of Service (QoS)

Summit WM series switch, access points, and WLAN switch software provides advanced Quality of

Service (QoS) management to provide better network traffic flow. Such techniques include:

● WMM (Wi-Fi Multimedia) – WMM is enabled per WM-AD.The Summit WM series switch provides

centralized management of these AP features. For devices with WMM enabled, the standard

provides multimedia enhancements for audio, video, and voice applications. WMM shortens the

time between transmitting packets for higher priority traffic. WMM is part of the 802.11e standard

for QoS.

● IP ToS (Type of Service) or DSCP (Diffserv Codepoint) – The ToS /D SC P field in the IP header of a

frame indicates the priority and QoS for each frame. The IP TOS and/or DSCP is maintained within

CTP (CAPWAP Tunneling Protocol) by copying the user IP QoS information to the CTP header—this

is referred to as Adaptive QoS.

Quality of Service (QoS) management is also provided by:

● Assigning high priority to an SSID (configurable)

● Adaptive QoS (automatic)

● Support for legacy devices that use SpectraLink Voice Protocol (SVP) for prioritizing voice traffic

(configurable)

System Configuration Overview

To set up and configure the Summit WM series switch and Altitude APs, follow these steps:

1 First-time Setup – Perform “First-Time Setup” of the Summit WM series switch on the physical

network to modify the Management Port IP address for the enterprise network.

2 Product Key – Apply a Product Key file, for licensing purposes. If no Product Key is enabled, the

Summit WM series switch functions with some features enabled in demonstration mode. Not all

features are enabled in this mode. For example, mobility is not enabled and cannot be used.

3 Data Port Setup – Set up the Summit WM series switch on the network by configuring the physical

data ports and their function as “host port”, “router port”, or “3rd party AP port”.

4 Routing Setup – Configure static routes and OSPF parameters for any port defined as a router port,

if appropriate to the network.

5 Altitude AP Initial Setup – Connect the Altitude APs to the Summit WM series switch. They will

automatically begin the Discovery of the Summit WM series switch, based on factors that include:

● Their Registration mode (in the Altitude AP Registration screen)

● The enterprise network services that will support the discovery process

A new feature of the 4.0 release is a default AP configuration. The default AP configuration

allows for a definition of a default configuration template, whereby APs automatically receive
