Nortel WLAN 2300 Series
Solution Brief

The Nortel WLAN 2300 Series is a complete 802.11 solution for enterprises wishing to deploy widespread wireless coverage for today’s business, IP Telephony and converged multimedia applications. The solution combines the latest industry standards with a centralized architecture and advanced features to create a secure, cost-effective and highly scalable WLAN infrastructure.

The WLAN 2300 Series includes the tools and features required for successful planning and implementation, whether deploying a first-time WLAN using a quick and simple approach, or graduating to a precisely engineered mobile infrastructure as part of a global enterprise mobility strategy. The WLAN 2300 Series features a centralized wireless LAN deployment model with “thin” access points controlled and managed by a central WLAN Security Switch. The series is comprised of four primary elements:

• WLAN Access Points
• WLAN Security Switches
• WLAN Management Software system
• WLAN Location Engine
Each plays a key role in the complete mobility solution.

• The Nortel WLAN 2300 Series Access Points perform 802.11a/b/g mobile connectivity, encryption/ decryption for wireless traffic, priority queuing and radio frequency (RF) monitoring, including rogue access point identification and containment. Access points exchange control and data traffic with their associated WLAN Security Switch.

• The Nortel WLAN 2300 family of security switches controls the access points and performs key functions such as security, networking, quality of service (QoS) and roaming for mobile users. The WLAN Security Switch also correlates radio frequency data from multiple access points and coordinates their response to changing RF conditions and RF attacks.

• The Nortel WLAN Management Software system is a comprehensive design and management tool that identifies ideal access point locations on detailed floor plans, configures all devices with a single click and provides granular monitoring and reporting for complete visibility and control over the entire system.

• The WLAN Location Engine is an optional element that adds integrated location services to any WLAN 2300 installation enabling new applications and services such as location-based security policies, content delivery or asset locating and tracking.

Support for 802.11n
The introduction of WLAN 802.11n into the marketplace represents an exciting time for customers due to its greatly enhanced capabilities over the existing 802.11 a/b/g standards, in terms of capacity, range and reliability. Refer to Figure 2 for an 802.11 a/b/g/n comparison. As part of WLAN 2300 Release 7, Nortel is introducing two Trapeze branded products — an 802.11n Access Point (Trapeze MP-432) and a new high capacity switch (Trapeze MX-2800). The Trapeze MP-432 AP will run on existing WLAN 23xx security switches. These are optional products, intended for those customers with an immediate need for 802.11n. Nortel’s recommendation is that before installing any new technology, particularly one based on a draft standard, it is important for customers to first consider all of the implications and create an approach that meets the needs and business goals of your organization. Deploying 802.11n involves much more than just an exchange of hardware and software. A wide range of issues need to be carefully considered (sidebar below), and developing a comprehensive plan spanning applications, clients and infrastructure is recommended.

Nortel’s WLAN 2300 Series advantage - A better user experience
The WLAN 2300 Series provides best in class performance to support delay sensitive applications like voice and multimedia. Seamless, fast roaming among all access points, dynamic RF management and QoS policy enforcement means that users get the highest quality WLAN experience possible — a must for IP Telephony and multimedia applications.

A better administrative experience
The WLAN 2300 Series makes life easier for administrators by automating tasks throughout the entire implementation and operations life cycle. The WLAN Management Software system provides an analytical site survey that considers three-dimensional RF attenuation characteristics of all elements that will impact WLAN coverage. Competing approaches often apply open-air scenarios to indoor floor plans without any adjustment for structure and materials.

The broad family of WLAN Security
Switches means that the right model can be deployed for any scenario. The access points automatically find and connect to WLAN Security Switches, and flexible AAA, QoS and security enforcement options allow for a seamless fit with existing policy structures and security equipment. The WLAN Management Software system also adopts new access points and WLAN Security Switches into an updated Wireless LAN topology. Real-time RF management handles unpredictable user loads and interference without the need for administrator intervention, and unlike competing solutions, the WLAN 2300 Series puts client performance first so that channel and power adjustments don’t disconnect active users. And extending the architecture to remote branch offices couldn’t be easier. WLAN Security Switches self-configure and ensure that WLAN service stays up even if WAN links fails. The WLAN 2300 Series even makes visitor-based networking a breeze. A unique streamlined application designed for front-desk personnel can be used to generate temporary guest IDs with expiration times and pre-configured access controls.

As for security, the WLAN 2300 Series goes beyond the latest industry security standards with built-in wireless threat protection that guards against RF-based attacks and vulnerabilities. The advanced RF scanning and control capability protects against unauthorized access points and ad-hoc users. Even the WLAN components themselves are authenticated before they’re accepted into the system and all subsequent control traffic is encrypted. And to make sure that the WLAN doesn’t add another layer of policy administration, the system will pull user policies directly from existing backend AAA servers, and bind those policies to users as they roam. Working together, the vast range of security capabilities ensures that user mobility doesn’t compromise the integrity of your network services.

A better return on your mobility investment
The number one expected benefit from WLAN investments is improved user productivity — which can only be realized if the WLAN service and supported applications perform to the user’s expectations. And usage patterns are changing quickly. Users are connecting more frequently with WLAN and staying connected longer than ever before. Add to this a parallel investment in IP Telephony and converged applications, combined with convenient desktop videoconferencing and the onslaught of new and embedded 802.11 clients, including dual-mode cellular/ Wi-Fi® phones, and it’s clear that demand for voice and multimedia over WLAN is imminent.

Whether you’re planning to adopt Voice over Wireless LAN today, or tomorrow, the WLAN 2300 Series is designed to deliver high-quality voice and converged services that are necessary to achieve real user productivity improvements. The system offers multiple levels of redundancy not found in competing solutions— access points can be dual-homed to find a backup connection should one fail, and WLAN Security Switches can be deployed in an active-standby configuration with n+1 redundancy and offer dual power supplies as well. Dynamic RF management, rogue access point protection and wireless threat protection will keep today’s mobile services and applications up and running during worst-case scenarios. Even the granular monitoring and reporting tools have been specifically designed for administrators who need to support business critical services.

WLAN Security Switch 2300 Series
The WLAN 2300 Series includes a family of security switches, each designed to meet specific needs of enterprise-wide deployments. The portfolio breadth, combined with advanced features and a common management system, provides unparalleled deployment flexibility and scalability to meet the growing demands of mobile professionals. Each switch can be deployed and managed independently, or can participate with other 2300 Security Switches in large enterprise network deployments. In multiple switch architectures, client information and policies are shared among switches to permit fast roaming among all access points. Regardless of network size or topology, the WLAN Security Switch 2300 family can lower equipment costs substantially by offering the right-sized product for any deployment scenario.

• Nortel WLAN Security Switch 2350

The WLAN Security Switch 2350 is the smallest switch in the 2300 Series and is ideally suited for extending WLAN services to small or branch office environments. The WLAN Security Switch 2350 auto-configures when first connected to the network
and can control up to three access points. It offers the same features as the larger 2300 switches but in a smaller package.

• Nortel WLAN Security Switch 2360

The WLAN Security Switch 2360 is ideally suited for mid-size office sites or wiring closet deployments and can control up to 12 access points that can be either connected directly to one of the eight Ethernet ports or indirectly through a Layer 2 or 3 network. The WLAN Security Switch 2361 is identical to the 2360, but adds a second power supply for improved wireless service resiliency.

• Nortel WLAN Security Switch 2382
The largest switch in the 2300 series features Gigabit connectivity and is designed for large deployments and data center installations. The WLAN Security Switch 2382 can be licensed to control up to 128 distributed access points. Dual power supplies provide superior resiliency for voice and business applications.

User-based policies for enhanced security
WLAN Security Switches can enforce security and QoS policies based on the individual user or group identity — not their device, initial access point or physical port. These policy assignments can be maintained locally, or pulled from central AAA servers during authentication. The latter approach allows for massive scale and stronger security by centralizing policy management and mitigating the need to update and synchronize multiple policy databases. Subsequent to authentication, user policies are propagated to other WLAN Security Switches to allow for fast, secure roaming with consistent QoS levels. The WLAN Security Switch tracks and maintains records of user location, roaming history, data transferred and other activity for accounting and billing purposes.

Mobility domains for “free” roaming
Each WLAN Security Switch controls a specified number of access points which in turn creates an 802.11 service domain where mobile users can roam freely. Multiple WLAN Security Switches can work together to create large mobility domains that can span multiple floors, an entire building or campus. Within the mobility domain, each user’s security, QoS and access policies follow them as they roam from access point to access point. Regardless of where a user roams, their traffic will always be tunneled back to the WLAN Security Switch that can put them on to the appropriate network VLAN and subnet. This roaming architecture ensures a symmetrical data flow and won’t break multi-cast memberships like competing solutions.

Virtual service groups for management flexibility
Each WLAN Security Switch can support up to 32 independent virtual WLANs over a single infrastructure. Each virtual WLAN can be set up as a unique service group that can be assigned its own VLAN, subnet and AAA server(s), along with specific security and QoS policies. In shared environments or managed services implementations, each virtual service group can have its own Web authentication page to request usernames and passwords or display instructions, welcome banners, corporate identities or advertisements.

AAA management/offloading offers authentication options
WLAN Security Switches are capable of enforcing multiple authentication options including client MAC address, 802.1X or Web-based authentication, and can map any SSID or virtual service group to a primary and backup AAA server, or load balance requests among multiple AAA servers for service resiliency. The WLAN Security Switch offloads back-end AAA servers by terminating and processing Extensible Authentication Protocol (EAP) for 802.1X users, including key generation and management functions for EAP-TLS, EAP-MD5 and PEAP. The WLAN Security Switch will also offload Transport Layer Security (TLS) processing, including X.509 certificate generation and management.

Centralized access point management provides simplified administration
Each WLAN Security Switch provides centralized management for the access points under its control. Firmware updates, configuration changes and RF management can all be performed by the WLAN Security Switch through a management interface or via Wireless Management Software. The WLAN Security Switch management system provides administrators with detailed tracking and reporting of activity on all access points.

Dynamic RF management ensures optimal coverage
The WLAN Security Switch continually receives RF data from associated access points and processes important information such as traffic load, interference from nearby devices, noise levels, client signal strength and signal-to-noise ratios. Using this data, the WLAN Security Switch calculates the optimal 802.11 channel assignments and radio power transmission levels for all associated access points. The WLAN Security Switch can automatically apply these settings to the respective access points and keep the WLAN system operating at peak performance and efficiency even when adverse or unexpected conditionsarise such as outages, interference or radio jamming attacks.

User RF optimization provides personalized performance
The WLAN Security Switch 2300 Series takes RF management to a new level by assimilating client RF data and client usage patterns, in addition to the basic RF data received from access points. The result is an auto-tuned RF environment that is optimized for user performance and usable capacity rather than blind approaches that achieve a theoretical balance among access points. By focusing on user performance, the WLAN 2300 keeps access points optimized for voice, multimedia and business applications.

Plug-n-Play/Plug-n-Grow
Traditional standalone WLAN deployments require careful planning and time-consuming reconfigurations of nearby access points whenever new ones are added to the network. The WLAN 2300 Series greatly simplifies this process by immediately recognizing new access points and dynamically incorporating them into the WLAN system with greatly minimized administrator intervention.

Rogue access point protection contains threats

WLAN Security Switches continually monitor RF activity and can identify unauthorized access points and clients that are broadcasting in the 802.11 radio spectrums. The system can identify and locate rogues, alert administrators, monitor the access point’s activity and even contain the threat by launching containment measures from neighboring access points. The system can also mirror suspicious wireless traffic on a user or group basis for security scanning.

Enhanced wireless threat protection goes beyond standards
Most of the recently introduced WLAN security standards like WPA2 and 802.11i address concerns relating to user authentication and data confidentiality/ integrity, but have done little to protect against RF-based attacks that focus on the WLAN infrastructure itself. The WLAN Security Switch 2300 series can protect against such attacks by comparing current RF activity to a built-in signature database and alerting administrators of a threat and location of the threatening device.

Control of third-party access points
WLAN Security Switches have the unique capability of being able to control popular standalone access points from other vendors. This allows IT departments to keep their existing access points and upgrade to a centralized architecture with many of the benefits of a complete WLAN 2300 system, including user based policy enforcement and fast roaming.

User load balancing for best performance

Large-scale WLANs can present mobile clients with multiple points of connectivity at any given time. If too many users connect to a particular access point, individual performance suffers and system capacity is reduced significantly. The WLAN 2300 Series continually monitors user load and will automatically redirect new users to alternative access points and deliver the best possible user performance for given conditions. Seamless fast roaming enables uninterrupted voice and multimedia services The WLAN 2300 Series allows seamless roaming between all access points. Mobile clients can roam between access points belonging to different subnets and even between those managed by a different WLAN Security Switch. Additionally, each user’s authentication information and associated policies are shared with other 2300 Series Security Switches so that the delay of re-authentication during roaming is eliminated. This allows users to maintain a voice quality connection while roaming within a particular area, between floors and even building-to-building.

Self-healing, resilient design minimizes service disruption

Each WLAN Security Switch maintains a map of RF characteristics within its service domain. In the event of an access point failure, the WLAN Security Switch will immediately recognize the change in RF patterns and respond by increasing transmission power levels of surrounding access points to fill the coverage hole. Similarly, if an access point is temporarily handicapped by a physical obstruction, the system will respond to minimize service disruption. The WLAN Security Switch hardware is also designed for resiliency with dual power supplies, Multi-Link Trunking, active-standby architecture options and n+1 redundancy for access point connectivity to eliminate any single points of failure within the system.

Clustering Support
Security switches can be configured in a cluster allowing them to act as a single virtual switch for wireless configurations and AP load balancing, which provides for automatic redundancy. This makes it easier to scale and improves resiliency. This capability solves most of the problems often faced by large-scale enterprises by providing a single point of configuration, automatic AP failover without client connection loss and AP load balancing.

WLAN 2300 Series Access Points

The WLAN Access Point 2332 is a multi-mode, dual-radio 802.11 a/b/g unit. It is controlled by the WLAN Security Switches and can be deployed in large numbers without creating a management burden. The APs are plenum-rated for ceiling installations and feature an attractive enclosure that resembles a common smoke detector to blend in with office environments. The Trapeze MP-432 is a dual-radio 802.11n unit. It is fully compliant with the 802.11n Draft 2 standard.

Simple installation
The WLAN Management Software system can be used to map the location of access points based on the expected number of users and type of applications being accessed. The WLAN Management Software system will also calculate each access point’s ideal configuration and push it out to the WLAN Security Switches which automatically configure the access points upon installation. The access points can connect directly to an Ethernet port on the WLAN Security Switch, or indirectly across a Layer 2 or 3 network and receive 803.3af Power over Ethernet (PoE) from a WLAN Security Switch, a PoE capable Layer 2/3 switch or PoE injector.

Resiliency and QoS for voice and multimedia applications
The WLAN 2300 series Access Points are designed to deliver reliable service for voice and multimedia applications and feature redundant Ethernet ports that allow for a backup network connection if the primary port fails for any reason. To deliver the best user experience, the access point classifies traffic into multiple user and group queues based on AAA-defined QoS policies, SVP or DiffServ classifications. The access point does not store any sensitive security information locally, making it safe for unsecured areas, and if theft is still a concern, then each access point can be physically locked down using the Kensington™ lock interface. To prevent tampering, each access point is authenticated to a WLAN Security Switch upon installation and all subsequent control traffic is encrypted.

RF scanning to prevent unauthorized activity

The WLAN 2300 series Access Points can perform scheduled or automated RF scans to search for unauthorized 802.11 devices and detect RF attacks. Access Points can run periodic sweeps of all channels in the active radio band while simultaneously providing mobile connectivity, or they can act as dedicated RF monitors and scan all bands and channels continuously. Any unauthorized activity or unexpected change in RF conditions is reported to the WLAN Security Switch, which determines if a rogue access point has been identified or if channel or power level adjustments are required.

Flexible antenna options for customizing signal patterns
The WLAN 2300 series Access Points are equipped with dual internal radios, omni-directional dual diversity antennas with external antenna connectors that allow enterprises to customize signal patterns and match particular deployment requirements.

WLAN Management Software system

The WLAN Management Software system is much more than a management application — it is an integrated tool suite that helps administrators through every phase of the project cycle from initial planning, deployment and configuration through ongoing operations support, troubleshooting and reporting. WLAN Management Software runs on common server platforms including Windows 2000, Windows XP and LINUX, and can support hundreds of individual WLAN Security Switches and thousands of access points. The WLAN Management Software system lets administrators perform system-wide updates with a single key stroke and “see” what’s happening at any moment with the rich graphical interfaces. The WLAN Management Software system is a client/server application and can support up to four simultaneous administrators, each with individual access levels and authorizations.

Painless planning and deployment
Prior to deployment, the WLAN Management Software system can act as a powerful standalone analytical site survey and planning tool that can import AutoCAD DXF™, AutoCAD DWG, JPEG or GIF floor plan files and apply attenuation characteristics to walls, doors, ceilings and other RF obstacles. The system can then design the ideal WLAN network including topology, equipment counts and radio channel and power settings. It even considers minimum user throughput levels, user volumes, failover and peak capacity scenarios to help engineers build service-ready WLANs for voice and converged applications. The WLAN Management Software system will map the access point’s physical location on floor plans and produce an accurate bill of materials to make installation as simple as possible, and once access points are installed, it can push configurations out to thousands of devices with a single key stroke to get the WLAN up and running as quickly as possible. The system can also import RF maps from an Ekahau™ site survey tool and overlay them on top of existing floor plans for an exact RF topology and more accurate rogue access point and user location. An open API can be used to export user location to third-party applications.

Ongoing operations
The WLAN Management Software system is designed to equip administrators with the powerful tools required to support wireless voice and converged services. The visual interface presents a top-level floor plan view that includes RF topology, access point, rogue access point and user location mapping with configurable alarms for ongoing moni-toring of the WLAN. Should an event occur, administrators can troubleshoot by drilling down to a granular level and see user roaming and usage history, RF and network statistics and hierarchical maps. The threat of rogue access points and ad-hoc users is mitigated through immediate identification, location and containment. All user, network and RF data, statistics and history can be captured in customizable reports and the planning tool can also be used on an ongoing basis to support configuration updates and new equipment deployments as the network grows. The WLAN Management Software system also features an HP OpenView plug-in to integrate with existing management systems.

WLAN Location Engine
The WLAN Location Engine 2340 is an integrated location services solution that uses the RF and user data captured by
the WLAN 2300 access points to resolve the location of thousands of mobile stations or asset tags simultaneously. This capability can be used to strengthen security with zone-based access controls, enable new services such as location specific content delivery, or as the foundation for new applications like asset tagging, locating and tracking. An application programming interface makes the location information accessible for any business application that can benefit from user location.

WLAN 2300 Accessories

The WLAN 2300 series supports a range of antennas for both indoor and outdoor use. This allows for improved deployment
flexibility where planners can choose an antenna pattern that meets coverage requirements while allowing for convenient AP placement and installation. Customers may use outdoor antennas for fringe coverage around and between buildings on an enterprise campus. This allows customers to extend their wireless LAN services outdoors, allowing them to enjoy the benefits of a single management system for outdoor use in courtyards, parking lots, the exteriors of a warehouse for shipping and control applications. Other applications include outdoor Internet access, security cameras, facilities dispatch and environmental controls. Optional power supplies are also available.
