- LLDP-MED - Link Layer Discovery Protocol for Media Endpoint Devices enhances VoIP deployments
- Flow Setup Throttling - (FST) effectively preempts and defends against DoS attacks
- Node & Alias Location - Automatically tracks user and device location and enhances network management productivity and fault isolation
- Port Protection Suite - Maintain network availability by ensuring good protocol and end station behavior
- Flex-Edge Technology - Provides advanced bandwidth management and allocation for demanding access/edge devices
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 especially important when reacting to security breaches. Extreme Networks K-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 Unified Communications, the Extreme Networks K-Series combines policy-based automation with support for multiple standards-based discovery methods, including LLDP-MED, SIP and H.323, to automatically identify and provision UC services for IP phones from all major vendors. K-Series switches also provide dynamic mobility for IP clients; when an IP phone moves and plugs in elsewhere in the enterprise network, its VoIP service provisioning, security and traffic priority settings move with it, with none of the typical manual administration required for moves, adds and changes.
The K-Series also supports a comprehensive portfolio of port protection capabilities, such as SPANguard and MACLock, which provide the ability to detect unauthorised 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.
Extreme Networks K-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.

Hardware-Based High Availability Features
The K-Series includes many standard high availability features. These hardware-based high availability features allow the K-Series to be deployed in mission critical environments that require 24/7 availability.
The K-Series supports the following hardware-based high availability features:
- Passive chassis backplane
- Hot swappable fan trays with multiple cooling fans
- Hot swappable and load-sharing power supplies
- Multiple AC input connections for power circuit redundancy
- Up to 36 groups of eight Ethernet ports can be grouped together to create a multi-link aggregation group (LAG)
Distributed, Flow-Based Architecture
In order to ensure granular visibility and management of traffic without sacrificing performance, the Extreme Networks K-Series deploys a flowbased 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 the switch and the I/O fabric module. 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 subsequent packets associated with that flow are automatically handled in the Extreme Networks ASICs without any further processing. In this way the Extreme Networks K-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 K-Series has unique, industry leading capabilities regarding types of simultaneous authentication methods. K-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 K-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 K-Series are determined on a per port, per I/O module, and per multi-slot system basis.
Multi-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 while protecting existing network investments. The K-Series supports up to 8 users per port with a license option for 256 users per port. Total system capacity supports 1152 users on the K6 and 1920 users on the K10.
Dynamic, Flow-Based Packet Classification
Another unique feature that separates the Extreme Networks K-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 K-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 Extreme Networks K-Series switch ports 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 more typical 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. 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 saves time and money by enabling administrators to know when and where upgrades might be needed.
Network Traffic Monitoring - Port Mirroring
Port mirroring is an integrated diagnostic tool for tracking network performance and security that is especially useful for fending off network intrusion and attacks. It is a low-cost alternative to network taps and other solutions that may require additional hardware, disrupt normal network operation, affect client applications or may introduce a new point of failure into your network.
Port mirroring is highly scalable and easy to monitor. It is especially convenient to use in networks where ports are scarce. Ports that can be configured to participate in mirroring include physical ports, virtual ports and host ports-VLAN interfaces, and intrusion detection ports. With this feature, analyzing bi-directional traffic and ensuring connectivity between, for example, a departmental switch and its high speed uplink to a backbone switch becomes simple and cost effective process.
K-Series port mirroring relationships can be set on inbound traffic, outbound traffic, or both for up to 4 port mirrors consisting of one-to-one, one-to-many, many-to-one, IDS or policy mirrors.
