The S-Series provides a highly resilient distributed switching and routing architecture with management and control functions embedded in each module, delivering unsurpassed reliability, scalability, and fault tolerance. Organizations can cost-effectively add connectivity as needed while scaling performance capacity with each new module. The highly available architecture makes forwarding decisions, and enforces security policies and roles while classifying/prioritizing traffic at wire speed. All I/O modules provide the highest Quality of Service Q( oS) features for critical applications such as voice and HD video even during periods of high network traffic load while also proactively preventing Denial of Service (DoS) attacks and malware propagation.
The S-Series implements an industry-leading, flow-based switching architecture to intelligently manage individual user and application conversations—far beyond the capabilities of switches that are limited to using VLANs, ACLs, and ports to implement role-based access controls. Users are identified and roles are applied to ensure each individual user can access their business-critical applications no matter where they connect to the network. S-Series policy rules combined with deep packet inspection can intelligently sense and automatically respond to security threats while improving reliability and quality of the user experience.
A significant differentiator for the S-Series is the ability toc ollect NetFlow data at wire-speed on every port, providing total visibility into network resource consumption for users and applications. The S-Series is the only enterprise switch to support multi-user, multi-method authentication on every port — absolutely essential when you have devices such as IP phones ,computers, printers, copiers, security cameras, badge readers, and virtual machines connected to the network. When quality of service, device and application prioritization, and security matters there is no better choice than the Extreme Networks S-Series.
Unified Cross-Platform Operating System
The Extreme Networks S-Series firmware adds the benefit of becoming a multi-platform operating system that unifies the Extreme Networks N-Series and S-Series into a single firmware image that operates on both platforms ensuring feature parity and consistent operation across the flow-based switches. This provides many customer benefits: reduced TCO via a single, unified operating system from network edge/access layer to the network core and data center, feature and function consistency across platforms, and easy deployment and upgrades to ensure operational efficiency.
Integrated Services Design
Integrated services design is a key differentiator that separates the Extreme Networks S-Series from the competition. Integrated services design reduces the number and type of modules required to build typical wiring closet configurations, simplifying the overall network design. In turn, this significantly reduces the maintenance and sparing cost as each I/O fabric or I/O module can perform all of these services, unlike competitive offerings with multiple dedicated module types for each specific service.

Network performance, management, and security capabilities via NetFlow are available on every S-Series I/O Fabric and I/O Module without affecting switching/routing performance or requiring the purchase of expensive daughter cards for every blade. The S-Series tracks every packet in every flow unlike competitor's statistical sampling techniques. The Extreme Networks advantage is the Extreme Networks ASIC capabilities that collect NetFlow statistics for every packet in every flow without sacrificing performance. Extreme Networks S-Series switches can output 9,000 flow records per second, per I/O module. This is an order of magnitude greater NetFlow performance than any other NetFlow appliance vendor (over 70,000 flow records per second in a fully populated S8 chassis).
Flow Setup Throttling (FST) is a proactive feature designed to mitigate zero-day threats and Denial of Service (DoS) attacks before they can affect the network. FST directly combats the effects of zero-day and DoS attacks by limiting the number of new or established flows that can be programmed on any individual switch port. This is achieved by monitoring the new flow arrival rate and/or controlling the maximum number of allowable flows.
In network operations, it is very time consuming to locate a device or find exactly where a user is connected. This is especialy important when reacting to security breaches. Extreme Networks S-Series modules automatically track the network's user/device location information by listening to network traffic as it passes through the switch. This information is then used to populate the Node/Alias table with information such as an end-station's MAC address and Layer 3 alias information (IP address, IPX address, etc). This information can then be utilized by Extreme Networks NMS Suite management tools to quickly determine the switch and port number for any IP address and take action against that device in the event of a security breach. This node and alias functionality is unique to Extreme Networks and reduces the time to pinpoint the exact location of a problem from hours to minutes.
For organizations looking to deploy VoIP technologies, the Extreme Networks S-Series provides significant capabilities through its support for the industrystandard discovery protocol, LLDP-MED (Link Layer Discovery Protocol for Media Endpoint Devices). This protocol allows for the accurate representation of network topologies within Network Management Systems (NMS). S-Series switches are able to learn about all the devices connected to them to identify VoIP phones, tell the phone which VLAN to use for voice, and even negotiate the power that the phone can consume. LLDP–MED also enables 911 emergency services location functions whereby the location of a phone can be determined by the switch port.
Extreme Networks S-Series support for Network Address Translation (NAT) provides a practical solution for organizations who wish to streamline their IP addressing schemes. NAT operates on a router connecting two networks, simplifying network design and conserving IP addresses. NAT can help organizations merge multiple networks together and enhance network security by helping to prevent malicious activity initiated by outside hosts from entering the corporate network; this improves the reliability of local systems by stopping worms and augments privacy by discouraging scans.
Within server farm environments, the S-Series can help to increase reliability and performance via the implementation of Load Sharing Network Address Translation (LSNAT). Based on RFC 2391, LSNAT uses a number of load sharing algorithms to transparently offload network load on a single server and distributes the load across a pool of servers.
The S-Series also supports a comprehensive portfolio of port protection capabilities, such as SPANguard and MACLock, which provide the ability to detect unauthorized bridges in the network and restrict a MAC address to a specific port. Other port protection features include Link Flap, Broadcast Suppression, and Spanning Tree Loop protection which protects against mis-configuration and protocol failure. The S-Series Virtual Switch Bonding technology allows two or more S-Series systems to create a single virtual switch.
Extreme Networks S-Series Flex-Edge technology provides line rate traffic classification for all access ports with guaranteed priority delivery for control plane traffic and high-priority traffic as defined by the Extreme Networks policy overlay. In addition to allocating resources for important network traffic, prioritized bandwidth can be assigned on a per port or per authenticated user basis. Flex-Edge technology is ideal for deployment in wiring closets and distribution points that can often suffer from spikes in utilization that cause network congestion. With Flex-Edge technologies, organizations no longer have to fear a momentary network congestion event that would result in topology changes and random packet discards.
CoreFlow2 policy enabled edge and core switches managed via NetSight play fundamental and essential roles in moving data reliably, efficiently and securely. The combined hardware and management suite provide superior traffic visibility, enforcement and security.
Traffic control and monitoring features include: Automatic application of ingress and egress policies for bi-directional traffic control; Rule Hit Accounting for network visibility and troubleshooting; and Flow Based Mirroring allowing for tapping individual traffic streams. Security features include: RA Guard (IPv6 Router advertisement containment) and features similar to DHCP Snooping, IP Source Guard and Dynamic ARP Inspection.

Hardware-Based High Availability Features
The S-Series includes many standard high availability features. These hardware-based high availability features allow the S-Series to be deployed in mission critical environments that require 24/7 availability.
The S-Series supports the following hardware-based high availability features:
- Passive chassis backplane in the S1, S3, S4, S6, and S8 chassis
- Meshed backplane architecture in the S3 chassis
- Hot swappable fan trays with multiple cooling fans
- Separate system and PoE power supplies
- Hot swappable power supplies
- Multiple AC input connections for power circuit redundancy
- Load sharing/redundant I/O fabrics in the S4, S6, and S8 chassis
- N+1 fabric redundancy in the S8 and S6 chassis
- Hot swappable I/O fabrics and I/O modules
- Multiple host CPU for N+X redundancy
- Virtual Switch Bonding (bonds two physical switches to create a single logical switch)
I/O Fabric and I/O Module Specifications:
The Extreme Networks S-Series chassis utilize both fabric-based point-to-point and fabric-less meshed forwarding architectures. The S1, S4, S6, and S8 chassis use a fabric-based forwarding architecture that provides multiple high bandwidth data paths between I/O modules, while the S3 chassis provides a high performance, fabric-less meshed forwarding architecture ideally suited for highly available network edge wiring closet deployments. All chassis are optimized for redundant high performance switching and routing as well as providing flexible connectivity and the ability to add features and scale performance as required and as new technologies become available.
I/O fabric modules provide scalable, high performance data paths as well as a full complement of front panel interfaces with flexible modular interface options. A single I/O fabric may be used in either an S1, S4, S6, or an S8 chassis, howeve,r the use of two I/O fabrics creates a load sharing fabric pai rthat provides up to 1280 Gbps switching capacity and adds high-avaialbility features. The S8 and S6 chassis augments the load sharing fabric pair by allowing the addition of a third I/O fabric module, increasing the system reliability and performance in the unlikely event of an I/O fabric failure. An S8 system with two I/O fabrics installed will gracefully reduce the fabric swtiching capacity by 50% in the event of an I/O fabric failure, however, when a third I/O fabric is installed the system will maintain a full 1280 Gbps of switching performance if an I/O fabric module were to fail. The load sharing fabric architecture ensures the highest availability and performance for the most demanding and mission-critical networks.
Extreme Networks S-Series I/O modules are high performance, fully-featured switch routers that deliver a fully distributed switching system as well as management and route processing capabilities, where each module is individually driven and managed by on-board processors. Extreme Networks flowbased ASICs, together with firmware microprocessors, create a traffic control solution that delivers high performance and flexibility. This distributed ASICbased architecture increases processing power as modules are added for a higher level of scalability and flexibility.
I/O fabrics and I/O modules are available with a wide array ofi nterface types and port densities (10/100/1000BASE-TX, 1000BASE-X SFP, and 10GBASE-X SFP+) to address varied network requirements. All triple speed copper I/O modules are PoE-enabled. A number of I/O modules also include either one or two option-module slots; an option-module slot provides additional media and port speed connectivity via triple speed copper, Gigabit SFP and 10 Gigabit SFP+ Ethernet option modules. This further simplifies network design and reduces the cost of network deployments. Al lS-Series I/O Fabrics and I/O Modules include very deep packet buffers per port to avoid dropped packets in the event of network congestion.
All S-Series 10 Gigabit Ethernet SFP+ ports are dual speed and will also accept standard Gigabit SFP transceivers. This capability enables a smooth migration path from Gigabit Ethernet for connecting devices to 10 Gigabit Ethernet in the future. Customers can use Gigabit Ethernet optical uplinks today and migrate to 10 Gigabit at their own pace. In addition, all Gigabit SFP ports will accept Fast Ethernet 100BASE-FX SFPs to enable connection of legacy devices.
S130 Class I/O Modules
S130 class I/O modules are optimized for use in wiring closetsf or user connectivity, in the distribution layer to aggregate edge switches, and in small and medium network cores. These modules provide high density with media flexibility and support for IEEE 802.3af PoE and IEEE 802.3at high power PoE standards. S130 class I/O modules deliver scalable triple speed performance and flexibility to ensure compatibility with today's high performance workstations, as well as legacy devices, while providing the highest levels of QoS, security, and bandwidth control via flow-based switching.
S130 class I/O modules include a unique feature that enables full line rate forwarding for bandwidth hungry workstations or when downstream switches are connected. Flex-Edge technology provides line rate forwarding through the switch even when the systems uplinks are in an oversubscribed state; this ensures that critical and time sensitive data pass through the switch to its destination at line rate, unlike inefficient methods used by other solutions on the market.
S130 class I/O modules support up to 512 users or eight authenitcated users per port in contrast to S150 class modules which support up to1 ,024 users/ devices per module with no restriction to the number of users per port. In cases where an S130 class I/O module needs to support more than 8 auhtenticated users per port, a software upgrade license may be purchased and applied to the module that removes this restriction. The S-EOS-PPC license is required for each S130 class I/O module that needs the 8 users per portr estriction removed. Only one S-EOS-PPC license is required for the S130 calss SSA switch. All S-Series triple speed I/O modules support PoE as standard, no additional daughter cards or software is required.
S150 Class I/O Modules
A selection of S-Series I/O modules are designed for use in the most demanding areas of the network where sustained high volumes of traffic are most common. Gigabit and 10 Gigabit Ethernet modules that incorporate advanced traffic management mechanisms and large packet buffers ensure optimal network performance and predictable reliability. S150 class I/O modules are optimized for the highly demanding performance and throughput requirements of enterprise network cores and data centers with high density line rate Gigabit and 10 Gigabit connectivity as well as industry-leading port type flexibility. S150 class I/O modules support the full range of Extreme Networks features and can be upgraded with advanced routing features as needed.

Optimized, High-Availability and Self Healing Services
Aside from the standard high-availability features of typical wiring closet and data center switches, the Extreme Networks S-Series includes many advanced self healing features such as dynamic service fail-over, automatic module self-configuration, and multi-image support.
Dynamic service fail-over enables each I/O module service (e.g., management, switching/VLANs, routing, etc.) to be automaticaly switched to another I/O module in an event of module or process failure. This "self healing" capability happens in milliseconds because each service is replicated in real-time on every I/O fabric and I/O module.
Automatic module self-configuration is another innovative feature that allows I/O modules to receive their configuration from other I/O modules automatically. This is ideal for replacing failed modules without manually reconfiguring the replacement module.
The Extreme Networks S-Series allows users to download and store multiple firmware image files; this feature is useful for reverting back to a previous version in the event that a firmware upgrade fails. This multi-image support provides significant operational efficiencies especially with regard to the application of firmware patches.
Distributed, Flow-Based Architecture
In order to ensure granular visibility and manage of traffic wihtout sacrificing performance, the Extreme Networks S-Series deploys a distributed, flow-based architecture. This architecture ensures that when a specific communications flow is being established between two end points, the first packets in that communication are processed through the multilayer classification engines in hte switch I/O modules and I/O fabric modules . In this process, the role is identified, the applicable policies are determined, the packets are inspected, and the action is determined. After the flow is identified, all usbsequent packets associated with that flow are automatically handled in the Extreme Networks ASICs without any further processing. In this way the Extreme Networks S-Series is able to apply a very granular level of control to each flow at full line rate.
Multi-User/Method Authentication and Policy
Authentication allows enterprise organizations to manage network access and provide mobility to users and devices. It provides a way to know who or what is connected to the network and where this connection is at any time. The Extreme Networks S- Series has unique, industry leading capabilities regarding types of simultaneous authentication methods. S-Series modules can support multiple concurrent authentication techniques, including:
- 802.1X authentication
- MAC authentication, which is a way to authenticate devices on the network using the MAC address
- Web-based authentication, also known as Port Web Authentication (PWA), where a user name and password are supplied through a browser
- CEP, also known as Convergence End Point, where multiple vendors VoIP phones are identified and authenticated; this capability provides great flexibility to enterprises looking to implement access control mechanisms across their infrastructure
A significant additional feature of the S-Series is the capability to support multi-user authentication. This allows multiple users and devices to be connected to the same physical port and each user or device to be authenticated individually using one of the multi-method options (802.1x, MAC, PWA, or CEP). The major benefit of multi-user authentication is to authorize multiple users, either using dynamic policy or VLAN assignment for each authenticated user. In the case of dynamic policy, this is called Multi-User Policy. Multi-user port capacities with the S-Series are determined on a per port, per I/O module, and per multi-slot system basis. Default I/O module capacities are detailed below.
Muti-user authentication and policy can provide significant benefits to customers by extending security services to users connected to unmanaged devices, third party switches/routers, VPN concentrators, or wireless LAN access points at the edge of their network. Using authentication provides security, priority, and bandwidth control are enhanced while protecting existing network investments. The S-Series supports up to 9000 concurrently authenticated users in a single system.
Dynamic, Flow-Based Packet Classification
Another unique feature that separates the Extreme Networks S-Series from all competitive switches is the capability to provide User- Based Multi-layer Packet Classification/QoS. With the wide array of network applications used on networks today, traditional Multi-layer Packet Classification by itself is not enough to guarantee the timely transport of businesscritical applications. In the S-Series, User-Based Multi-layer Packet Classification allows traffic classification not just by packet type, but also by the role of the user on the network and the assigned policy of that user. With User-Based Multi-layer Packet Classification, packets can be classified based on unique identifiers like "All Users", "User Groups", and "Individual User", thus ensuring a more granular approach to managing and maintaining network confidentiality, integrity, and availability.
Network Visibility From High Fidelity NetFlow
Network performance management and security capabilities via NetFlow are available on every Extreme Networks S-Series switch port without slowing down switching and routing performance or requiring the purchase of expensive daughter cards for every module. Extreme Networks NetFlow tracks every packet in every flow as opposed to competitor's statistical sampling techniques or restrictive appliance-based implementations. The value of unsampled, real-time NetFlow monitoring is the visibility into exactly what traffic is traversing the network and if something abnormal occurs it will be captured by NetFlow and appropriate action can be applied. Additionally, NetFlow can be used for capacity planning allowing the network manager to monitor the traffic flows and volumes of traffic in the network and understand where the network needs to be reconfigured or upgraded. This will save time and money, by enabling administrators to know when and where upgrades might be needed. The S-Series flow monitoring capabilities are industry leading, it can concurrently monitor in excess of 70,000 flows per second, a far greater capacity than any other vendors switch or router.
