ExtremeWireless Virtual Network Services control trac
flow by allowing trac to be backhauled to a wireless
appliance or switched locally at the AP on a per SSID basis.
With local switching, the AP is still managed centrally by
the wireless appliance, but data is not backhauled to the
wireless appliance. This improves responsiveness and
ensures that trac does not unnecessarily traverse costly
WANs or contribute to bottlenecks at aggregating switches.
A VNS also provides role-based policies providing security,
NAC, mobility, and QoS priority that can be implemented
on a per user and per application basis. The table below

Integrated Management and
Control Across Wireless and
Wired Networks
Web-based Centralized Management via
Wireless Assistant
The Wireless Assistant provides network administrators
with a centralized web-based interface designed to
easily manage both infrastructure and services. Hosted
on the wireless appliance, this interface allows network
administrators to separately configure, enable, or
disable each AP or group of APs. The wireless appliance
consolidates data received from across the network to
provide meaningful statistics in easy-to-read reports.
Additionally, a number of standards-based management
tools are available to facilitate integration of the WLAN
infrastructure with enterprise management applications. For
large networks with multiple wireless appliances the optional
ExtremeControl Management Suite can be used to collect
and manage data for a centralized view of the entire WLAN.
Multi-Appliance Management
ExtremeControl provides centralized management for the
ExtremeWireless portfolio, consolidating management
information from across the entire WLAN for a global
network perspective. The solution is enhanced by the
addition of ExtremeWireless Radar Intrusion Prevention
System (WIPS) option which provides sophisticated
wireless intrusion prevention and location assessment
capabilities. Wired and wireless network integration
is further enhanced by the visibility of all the wireless
elements through the ExtremeControl Management
Suite. Integration between ExtremeControl and the
ExtremeWireless portfolio provides end-to-end visibility
of wireless access points, appliances, and wireless clients
from the ExtremeControl Center Console. The integration
delivers improved network management eciency and
wired/wireless infrastructure topology mapping and
visibility for network administrators.Further integration
with ExtremeControl Center Inventory Manager eectively
centralizes distribution of software and tracking of
configuration changes.
Integrated Security
Wireless IDS and IPS enhances security with embedded
wireless intrusion prevention through ExtremeWireless
Radar. When deployed in conjunction with the
ExtremeSecurity Intrusion Prevention System (IPS), full
packet inspection, adaptive signature pattern matching,
protocol analysis, and behavioral anomaly detection
are delivered for both wired and wireless users. Further,
ExtremeControl’s identity based policy privileges are
unified across the wired and wireless infrastructure
to deliver role-based access control – regardless of
connectivity method.
The ExtremeControl policies ensure only the right users
have access to the right information, from the right place,
at the right time. Third party authentication systems can
also be integrated with the use of the External Captive
Portal interface.
High Performance and High Availability
ExtremeWireless delivers the perfect combination of
high- performance and high-availability demanded by
today’s wireless applications. By combining unique voice
optimization features and the latest in industry standards,
ExtremeWireless provides enterprise grade reliability for
all users.
High Scalability
The ExtremeWireless portfolio supports from a single
AP to 2,000 APs per wireless appliance, providing linear
scalability from small to large wireless deployments. In
addition, wireless appliances can be networked to scale
beyond the limits of a single appliance or availability pair
to oer a multi-wireless appliance mobility zone. Mobility
