Benefits of Wired and Wireless Integration

ProCurve Wireless Edge Services Modules, working in

conjunction with ProCurve Radio Ports, simplify the

deployment and management of a wireless LAN by

seamlessly integrating centralized RF management,

advanced wireless services and secure wireless network

access control into ProCurve's line of premier xl and zl

switch chassis family.

This modular approach to enabling wireless services also

simplifies network design and deployment by leveraging

the inherent benefits of a chassis architecture, including

choice of port type, density and Power over Ethernet

(PoE) capability, in addition to modular expansion to

scale as network needs change. Further, greater

resiliency results from using ProCurve switching

capability as much as possible for deployment of

mobility services, rather than relying on a separate

dedicated overlay.

ProCurve intelligent edge switches already offer identity-

driven access control to network resources over wired

network connections. With the addition of the ProCurve

Wireless Edge Services Modules, these same role-based

access policies, dynamically generated by built-in

support for ProCurve Identity Driven Manager, are also

enforced across the wireless edge for wireless clients

connecting to the network through ProCurve Radio Ports.

This unified approach to wired and wireless policy

management provides edge-enforced security and

network access control on every network connection

regardless of whether a user connects to the network

wirelessly or through a wired port. Moreover, wired and

wireless users are presented with a consistent and

personalized view of the network based on user identity

and time of day.

The ProCurve wireless LAN systems also take advantage

of the Switchs' built-in connection-rate filtering based on

Virus Throttle technology. This ProCurve-developed

solution addresses new threats not yet recognized by

virus protection software. With Virus Throttle

technology, ProCurve WLAN systems are able to

automatically discover attacks originating by wired or

wireless devices and rate-limit or even block infected

traffic from entering the network, giving network

managers the time necessary to implement a response.

Advanced Wireless Services

ProCurve Wireless Edge Services Modules provide a

single point to configure system-wide wireless LAN

setup and operation, including SSID, security and

authentication options as well as advanced wireless

services. Wireless LAN settings are automatically

administered to designated ProCurve Radio Ports,

eliminating the cost and time associated with individual

configuration of access points. Advanced wireless

services include the following:

• Network self-healing: In the event of a radio port

failure, the module will automatically adjust

transmission power and data rate on adjacent ProCurve

Radio Ports to maintain wireless LAN coverage.

• RF detection and interference avoidance: The system

automatically recalibrates radio port channel

assignments to avoid environmental or other

802.11-based wireless interference.

• Wireless intrusion detection: Wireless Edge Services

Modules can also guard against hackers who use

wireless stations to launch attacks, monitoring stations

for suspicious behavior that may signal a denial-of-

service (DoS) attack.

• Stateful packet inspection firewall: Inspects and drops

routed packets with invalid TCP flags, corrupted packets

and stops common DoS attacks.

• Fast, secure roaming: Enables seamless, fast Layer 2

roaming with pre-cached authentication credentials

for wireless users to help enable real-time business

applications.
