Overview of the Summit WM Controller, Access Points and Software Solution
If a Summit WM Controller fails, all of its associated Wireless APs can automatically switch over to
another Summit WM Controller that has been defined as the secondary or backup Summit WM
Controller. If the AP reboots, the original Summit WM Controller is restored. The original Summit WM
Controller 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)
The Summit WM Controller, Access Points and 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 Controller 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/DSCP 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 Controller and Wireless APs, follow these steps:
1 First-time Setup – Perform "First-Time Setup" of the Summit WM Controller 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 Controller functions with some features enabled in demonstration mode. Not all
features are enabled in this mode.
3 Data Port Setup – Set up the Summit WM Controller 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 Wireless AP Initial Setup – Connect the Wireless APs to the Summit WM Controller. They will
automatically begin the Discovery of the Summit WM Controller, based on factors that include:
Their Registration mode (in the Wireless AP Registration screen)
●
The enterprise network services that will support the discovery process
●
The default AP configuration allows for a definition of a default configuration template, whereby
APs automatically receive complete configuration. For typical deployments where all APs are to all
