Customer-Driven Networking Data Sheet Highlights ExtremeXOS has a robust set of Layer 2 and Layer 3 control protocols, provides a flexible architecture for highly resilient networks and has been designed to support the nextgeneration Internet Protocol, IPv6. ExtremeXOS is a highly available and extensible software foundation for converged networks. ExtremeXOS offers high availability for carriergrade voice and video services over IP and for supporting mission-critical business applications such as CRM. • Modular Operating System • High Availability Architecture • Rich set of Layer-2 and Layer-3 protocols and features • Secure Network Access through role based policy or Identity Management • Extensibility • Integrated Security with NetLogin, MAC Security, IP Security • User, location, and time-based dynamic security policies with Identity Management • Insight, control and automation for virtualized data centers with XNV (ExtremeXOS Network Virtualization) • Enhanced resiliency, synchronization, performance for 2G/3G/4G mobile backhaul • ExtremeXOS InSite SDK Software Defined Networking Ready with OpenFlow and OpenStack support • Ethernet Audio Video Bridging (AVB) enabled ExtremeXOS' Operating System Version 16.2, 21.1, 22.7, and 30.3 Overview Extreme Networks has created the ExtremeXOS modular Operating System (OS) - for highly available, extensible, high-performance networks. ExtremeXOS high availability architecture with EAPS protocol helps reduce network downtime for business continuity and access to mission-critical applications such as CRM, data warehouses and VoIP for carrier and voice grade networks. Built-in security capabilities provide network access control integrated with endpoint integrity checking, identity management, and protection for the network control and management planes. With ExtremeXOS you can extend the capabilities of your network by integrating specialized application appliances such as security devices into the network, providing insight and control at the network, application and user level. Architectural Highlights • Memory protection for processes • Self-healing process recovery via process restart or hitless failover • Dynamic loading of new functionality • Scriptable CLI for automation and event-triggered actions • XML open APIs for integrating third-party applications • Dual-stack IPv4 and IPv6 support

Denial of Service Protection ExtremeXOS switches provides effective Denial of Service (DOS) attack protection. If the switch detects an unusually large number of packets in the CPU input queue, it assembles ACLs that automatically stop these packets reaching CPU. After a period of time these ACLs are removed, and reinstalled if the attach continues. ASIC-based LPM routing eliminates the need for control plane software to learn new flows, allowing more network resiliency against DOS attacks. Extensibility Dynamic Module Loading ExtremeXOS provides an infrastructure to dynamically load, start...

routes. It is a scalable technique for measuring network traffic, and collecting, storing, and analyzing traffic data. This enables thousands of interfaces to be monitored from a single location. sFlow is scalable, thereby enabling it to monitor links of speeds up to 10 Gigabits per Second (Gbps) and beyond without impacting the performance even of core Internet routers and switches, and without adding significant network load. IPFIX (Internet Protocol Flow Information eXport), or RFC 3917, can be used as an alternative to sFlow. IPFIX offers templates for the data to be transferred, or...

benefit of multiuser authentication is to authorize multiple users, either using dynamic policy or VLAN assignment for each authenticated user. Multi-user authentication and role-based policy can provide significant benefits to customers by extending security services to users connected through unmanaged devices, third party switches/routers, VPN concentrators, or wireless LAN access points at the edge of their network. Authentication provides security, priority, and bandwidth control while protecting existing network investments. Integrated Security Role-Based Policy Utilizing...

Switching: Network Resiliency and Forwarding Control Layer 2+ For network resiliency, ExtremeXOS offers a choice between standard protocols and more advanced Layer 2+ protocols, optimized for faster resiliency, larger scaling and simpler operation. Spanning Tree Protocol: ExtremeXOS supports IEEE 802.1D STP, 802.1w RSTP and 802.1s MSTP. In Extreme Multiple Instance STP mode, ExtremeXOS allows a port or VLAN to belong to multiple STP domains and therefore adds flexibility to STP network design, further increasing resiliency. The implementation is also compatible with PVST+ and IEEE 802.1Q....

Designed For Cloud Data Centers and Central Office Direct Attach (VEPA) With optional feature pack, EXOS can support Direct Attach (VEPA), which eliminates the virtual switch layer, simplifying the network and improving performance. Direct Attach enables data center simplification by reducing network tiers from 4 or 5 tiers to just 3 or 2 tiers, depending on the size of the data center. ExtremeXOS Network Virtualization (XNV) To further enhance data center operations, EXOS supports XNV (ExtremeXOS Network Virtualization), which is natively supported in the ExtremeXOS operating system. XNV...
