1 The Summit WM-Series Switch Software
solution
The next generation of Extreme Networks wireless networking devices provides a truly scalable WLAN solution. Extreme Networks Altitude APs are thin access points that are controlled through a sophisticated network device, the Summit WM-Series Switch. This solution provides the security and manageability required by enterprises and service providers alike.
The Summit WM-Series Switch Software system is a highly scalable wireless local area network (WLAN) solution developed by Extreme Networks. Based on a third generation WLAN topology, the Summit WM-Series Switch Software system makes wireless practical for medium and large-scale enterprises and for service providers.
The Summit WM-Series Switch Software system provides a secure, highly scalable, cost-effective solution based on the IEEE 802.11standard. The solution is intended for enterprise networks operating on many floors in more than one building, as well as in public environments such as airports and convention centers that require more than two access points.
This section provides an overview of the fundamental principles of the Summit WM-Series Switch Software system: what it is, how it works, and its advantages.
What is the Summit WM-Series Switch Software system?
The Summit WM-Series Switch Software system replaces the conventional access points used in wireless networking with two network devices that work as a system:
Summit WM-Series Switch: A network device that provides smart centralized control over the
elements (Altitude APs) in the wireless network.
Altitude APs: The access points for 802.11 clients (wireless devices) in the network, controlled by the
Summit WM-Series Switch. The Altitude AP is a “fit access point” because its wireless control is handled by the Summit WM-Series Switch. The Altitude AP is a dual-band access point, with both
802.11a and 802.11b/g radios.
Together, the Summit WM-Series Switch Software products enable a radically simplified new approach to setting up, administering and maintaining a WLAN. Summit WM-Series Switch Software provides a Layer 3 IP routed WLAN architecture. This architecture can be implemented over several subnets without requiring the configuration of virtual local area networks (VLANs).
Conventional wireless LANS
At its simplest, wireless communication between two or more computers requires that each one is equipped with a receiver/transmitter – a WLAN Network Interface Card (NIC) – capable of exchanging digital information over a common radio frequency. This is called an ad hoc configuration. An ad hoc network allows wireless devices to communicate together. This is an independent basic service set (IBSS).
Summit WM-Series WLAN Switch and Altitude Access Point Software Version 1.0 User Guide
13
The Summit WM-Series Switch Software solution
An alternative to the ad hoc configuration is the use of an access point. This may be a dedicated hardware router or a computer running special software. Computers and other wireless devices communicate with each other through this access point. The 802.11 standard defines Access Point communications as devices that allow wireless devices to communicate with a “distribution system”. This is a basic service set (BSS) or infrastructure network.
For the wireless devices to communicate with computers on a wired network, the access points must be connected into the wired network, and provide access to the networked computers. This is called bridging. Clearly, there are security issues and management scalability issues in this arrangement.

The wireless devices and the wired networks communicate with each other using standard networking protocols and addressing schemes. Most commonly, Internet Protocol (IP) addressing is used.
While this topology works well enough for small installations, as the network grows the difficulty of setting up and administering all the individual access points expands as well. When the expanding network has to cope with a large number of wireless users all signing on and off at random times, the complexity grows rapidly. Imagine, for example, a university library filled with professors and students – all equipped with laptops. Or a conference full of delegates and exhibitors.
14
Clearly, there must be a better way than setting up each access point individually.
The Summit WM-Series Switch Software solution
The Summit WM-Series Switch Software solution consists of two devices:
The Summit WM-Series Switch is a rack-mountable network device designed to be integrated into an
existing wired Local Area Network (LAN). It provides centralized control over all access points (both Altitude APs and third-party access points) and manages the network assignment of wireless device clients associating through access points.
The Altitude AP is a wireless LAN fit access point (IEEE 802.11) provided with unique software that
allows it to communicate only with a Summit WM-Series Switch. (A fit access point handles the radio

What is the Summit WM-Series Switch Software system?
frequency (RF) communication but relies on a controller to handle WLAN elements such as authentication.) The Altitude AP also provides local processing such as encryption.
This architecture allows a single Summit WM-Series Switch to control many Altitude APs, making the administration and management of large networks much easier.
There can be several Summit WM-Series Switchs in the network, each with its set of registered Altitude APs. The Summit WM-Series Switchs can also act as backups to each other, providing stable network availability.
In addition to the Summit WM-Series Switchs and Altitude APs, the solution requires three other components, which are standard for enterprise and service provider networks:
RADIUS Server (Remote Access Dial-In User Service) (RFC2865 and RFC2866), or other
authentication server. Assigns and manages ID and Password protection throughout the network. Used for authentication of the wireless users.
DHCP Server (Dynamic Host Configuration Protocol) (RFC2131). Assigns IP addresses, gateways
and subnet masks dynamically. Also used by the Altitude APs to discover the location of the Summit WM-Series Switch during the initial registration process.
SLP (Service Location Protocol) (RFC2608) supported on the DHCP server, when SLP is used as part
of the discovery mechanism.

The Summit WM-Series Switch has built-in capabilities to recognize and manage the Altitude APs. The Summit WM-Series Switch activates the Altitude APs, enables them to receive wireless traffic from wireless devices, processes the data traffic from the Altitude APs and forwards or routes that data traffic out to the network. This processing includes authenticating requests and applying access policies.

Components of the solution: a summary
The following is a summary checklist of the components of the Summit WM-Series Switch Software solution on your enterprise network. These are described in detail in this guide.
The Summit WM-Series Switch, providing centralized control over all access points (both Altitude
APs and third-party access points) and manages the network assignment of wireless device clients associating through access points.
The Altitude AP is a wireless LAN thin access point (IEEE 802.11) that communicates only with a
Summit WM-Series Switch.
RADIUS Server (Remote Access Dial-In User Service) (RFC2865), or other authentication server.
Assigns and manages ID and Password protection throughout the network. Used for authentication of the wireless users in either 802.1x or Captive Port security modes.
The RADIUS Server system can be set up for certain standard attributes, such as Filter-ID, and for the Vendor Specific Attributes (VSAs).
DHCP Server (Dynamic Host Configuration Protocol) (RFC2131). Assigns IP addresses, gateways
and subnet masks dynamically. IP address assignment for clients can be done by the DCHP server internal to the Summit WM-Series Switch, or by existing servers using DHCP relay. Also used by the Altitude APs to discover the location of the Summit WM-Series Switch during the initial registration process. For SLP, DHCP should have Option 78 enabled (Option 78 specifies the location of one or more SLP Directory Agents).
Service Location Protocol (SLP) (SLP RFC2608). Client applications are User Agents and services are
advertised by Service Agents. In larger installations, a Directory Agent collects information from Service Agents and creates a central repository. The Extreme Networks solution relies on registering “extreme” as an SLP Service Agent.
Domain Name Server (DNS), for an alternate mechanism (if present on the enterprise network) for
the automatic discovery process. Summit WM-Series Switch Software relies on the DNS for Layer 3 deployments and for static configuration of Altitude APs. The Extreme Networks solution relies on registering “controller” as the DNS name.
Web Authentication Server, if desired for external authentication.
RADIUS Accounting Server (Remote Access Dial-In User Service) (RFC2866), if RADIUS
Accounting is enabled.
Simple Network Management Protocol (SNMP) Manager Server, if forwarding SNMP messages is
enabled.
Check Point Server, Check Point Event Logging API (ELA), for security event logging if a firewall
application is enabled.

The diagram above shows a simple configuration with a single Summit WM-Series Switch and two Altitude APs, each supporting a wireless device. A RADIUS server on the network provides authentication, and a DHCP server is used by the Altitude APs to discover the location of the Summit WM-Series Switch during the initial registration process. Also present in the network are routers and ethernet switches.
18
Each wireless device sends IP packets in the 802.11 standard to the Altitude AP. The Altitude AP uses a UDP (User Datagram Protocol) based tunnelling protocol to encapsulate the packets and forward them to the Summit WM-Series Switch.
The Summit WM-Series Switch decapsulates the packets, and routes these to destinations on the network, after authentication by the RADIUS server.
The Summit WM-Series Switch functions like a standard router, except that it is configured to route only network traffic associated with wireless connected users. The Summit WM-Series Switch can also be configured to simply forward traffic to a default or static route if dynamic routing is not preferred.

Summit WM-Series Switch Software and your network
Network security
The Summit WM-Series Switch Software system provides features and functionality to control network access. These are based on standard wireless network security practices.
Current wireless network security methods provide a degree of protection. These methods include:
Shared Key authentication that relies on Wired Equivalent Privacy (WEP) keys
Open System that relies on Service Set Identifiers (SSIDs)
802.1x that is compliant with Wi-Fi Protected Access (WPA)
Captive Portal based on Secure Sockets Layer (SSL) protocol
The Summit WM-Series Switch Software system supports these encryption approaches:
Wired Equivalent Privacy (WEP), a security protocol for wireless local area networks defined in the
802.11b standard
Wi-Fi Protected Access version 1 (WPA1
Wi-Fi Protected Access version 2 (WPA2
Mode with Chipher Block Chaining Message Authentication Code (CCMP).
TM
) with Temporal Key Integrity Protocol (TKIP)
TM
) with Advanced Encryption Standard (AES) and Counter
Authentication
The Summit WM-Series Switch relies on a RADIUS server, or authentication server, on the enterprise network to provide the authentication information (whether the user is to be allowed or denied access to the network).
The Summit WM-Series Switch provides authentication using:
Captive Portal, a browser-based mechanism that forces users to a web page
RADIUS (using IEEE 802.1x)
The 802.1x mechanism is a standard for authentication developed within the 802.11 standard. This mechanism is implemented at the port, blocking all data traffic between the wireless device and the network until authentication is complete. Authentication by 802.1x standard uses Extensible Authentication Protocol (EAP) for the message exchange between the Summit WM-Series Switch and the RADIUS server.
When 802.1x is used for authentication, the Summit WM-Series Switch provides the capability to dynamically assign per-wireless-device WEP keys (called per-station WEP keys in 802.11).
In Summit WM-Series Switch Software, a RADIUS redundancy feature is provided, where you can define a failover RADIUS server (up to 2 servers) in the event that the active RADIUS server fails.
Privacy
Privacy is a mechanism that protects data over wireless and wired networks, usually by encryption techniques.
Summit WM-Series Switch Software supports the Wired Equivalent Privacy (WEP) standard common to conventional access points.
Summit WM-Series WLAN Switch and Altitude Access Point Software Version 1.0 User Guide

The Summit WM-Series Switch Software solution
It also provides Wi-Fi Protected Access version 1 (WPA v.1) encryption, based on Pairwise Master Key (PMK) and Temporal Key Integrity Protocol (TKIP). The most secure encryption mechanism is WPA version 2 using Advanced Encryption Standard (AES).
Interaction with wired networks: Wireless Mobility Access Domain
Summit WM-Series Switch Software provides a versatile means of mapping wireless networks to the topology of an existing wired network. This is accomplished through the assignment of WM Access Domain Services.
When you set up WM Access Domain Services (WM-AD) on the Summit WM-Series Switch, you are defining subnets for groups of wireless users. This WM-AD definition creates a virtual IP subnet where the Summit WM-Series Switch acts as a default gateway for wireless devices.
This technique enables policies and authentication to be applied to the groups of wireless users on a WM-AD, as well as the collecting of accounting information on user sessions that can be used for billing.
When a WM-AD is set up on the Summit WM-Series Switch:
one or more Altitude APs (by radio) are associated with it
a range of IP addresses is set aside for the Summit WM-Series Switch’s DHCP server to assign to
wireless devices
If routing protocol is enabled, the Summit WM-Series Switch advertises the WM-AD as a routable network segment to the wired network, and routes traffic between the wireless devices and the wired network.
Each radio on a Altitude AP can participate in up to four WM-ADs, via the multi-SSID function.
Static routing and routing protocols
Routing can be used on the Summit WM-Series Switch to support the WM-AD definitions.
In the User Interface, you can configure routing on the Summit WM-Series Switch to use one of the following routing techniques:
Static routes: Use static routes to set the default route of a Summit WM-Series Switch so that
legitimate wireless device traffic can be forwarded to the default gateway.
Open Shortest Path First (OSPF, version 2) (RFC2328): Use OSPF to specify the next best hop (route)
of a Summit WM-Series Switch. Open Shortest Path First (OSPF) is a protocol designed for medium and large IP networks, with the ability to segment routers into different routing areas for routing information summarization and propagation.
Next Hop Routing: Use next hop routing as part of a WM-AD definition to specify a unique default
gateway to which traffic on a unique WM-AD is forwarded.

Summit WM-Series WLAN Switch and Altitude Access Point Software Version 1.0 User Guide
Summit WM-Series Switch Software and your network
Policy: packet filtering
Policy refers to the rules that allow different network access to different groups of users. The Summit WM-Series Switch Software system can link authorized users to user groups. These user groups then can be confined to predefined portions of the network.
In the Summit WM-Series Switch Software system, policy is carried out by means of packet filtering, within a WM-AD.
In the Summit WM-Series Switch user interface, you set up a filtering policy by defining a set of hierarchical rules that allow (or deny) traffic to specific IP addresses, IP address ranges, or services (ports). The sequence and hierarchy of these filtering rules must be carefully designed, based on your enterprise’s user access plan.
The authentication technique selected determines how filtering is carried out:
If authentication is by SSID and Captive Portal, a non-authenticated filter will allow all users to get
as far as the Captive Portal web page, where login occurs. When authentication is returned, then filters are applied, based on user ID and permissions.
If authentication is by AAA (802.1x), users will already have logged in and have been authenticated
before being assigned an IP address. At this point, filters are applied, based on user ID and permissions.
Mobility and roaming
The 802.11 standard allows a wireless device to preserve its IP connection when it roams from one access point to another on the same subnet. However, if a user roams to an access point on a different subnet, the user is disconnected.
Summit WM-Series Switch Software has functionality that supports mobility on any subnet in the network. Wireless device users can roam between Altitude APs on any subnet without having to renew the IP connection.
The Summit WM-Series Switch stores the wireless device’s current session information, such as IP address and MAC address. If the wireless device has not disassociated, then when it requests network access on a different Altitude AP, the Summit WM-Series Switch can match its session information and recognize it as still in a current session.
In addition, a Summit WM-Series Switch can learn about other Summit WM-Series Switches on the network, and then exchange client session information. This enables a wireless device user to roam seamlessly between different Altitude APs on different Summit WM-Series Switches.

Availability
Summit WM-Series Switch Software provides seamless availability against Altitude AP outages, Summit WM-Series Switch outages, and even network outages.
For example, if one Altitude AP fails, coverage for the wireless device is automatically provided by the next nearest Altitude AP.
If a Summit WM-Series Switch fails, all of its associated Altitude APs, or access points, can automatically migrate to another Summit WM-Series Switch that has been defined as the secondary or backup Summit WM-Series Switch. When the original Summit WM-Series Switch returns to the network, the Altitude APs automatically re-establish their normal connection with their original Summit WM-Series Switch.
Quality of Service (QoS)
Summit WM-Series Switch Software provides advanced Quality of Service (QoS) management, in order to provide better network traffic flow. Such techniques include:
WMM (Wi-Fi Multimedia): enabled globally on the Altitude AP. 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 is used to indicate the priority and Quality of Service 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)
