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.
2.3.8 Quality of Service (QoS)
Controller, Access Points and Convergence 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 VNS. The HiPath Wireless
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)
2.4 System Configuration Overview
To set up and configure the HiPath Wireless Controller and Wireless APs, follow
these steps:
1. First time Setup – Perform “First Time Setup” of the HiPath Wireless
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 HiPath Wireless Controller 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.
