Extreme Networks Data SheetVoice-Class AvailabilityPowered by the ExtremeXOS, Summit X450a supports process recovery and application upgrades without the need for asystem reboot. Summit X450a provides the high network availability required for converged applications.Modular Operating Systemfor Non-Stop OperationTrue Preemptive Multitaskingand Protected MemoryThe Summit X450a series switch allowseach of the many applications—such asOpen Shortest Path First (OSPF) andSpanning Tree Protocol (STP)—to runas separate OS processes that areprotected from each other. This drivesincreased system integrity and inherently protects against DoS attacks.Process Monitoring and RestartExtremeXOS dramatically increasesnetwork availability using processmonitoring and restart. Each independentOS process is monitored in real time. If aprocess becomes unresponsive or stopsrunning, it can be automatically restarted.Loadable Software ModulesThe modular design of ExtremeXOSallows the upgrading of individualsoftware modules, should this be necessary,leading to higher availability in the network(see Figure 1).number of VLANs, network nodes ornetwork topology. Since EAPS allows thenetwork to recover almost transparently,Voice-over-IP calls will not drop and digitalvideo feeds will not freeze or pixelize inmost situations.Spanning Tree/Rapid SpanningTree ProtocolsThe Summit X450a series supportsSpanning Tree (802.1D), Per VLANSpanning Tree (PVST ), Rapid SpanningTree (802.1w) and Multiple Instances ofSpanning Tree (802.1s) protocols forLayer 2 resiliency.Software-Enhanced AvailabilitySoftware-enhanced availability allowsusers to remain connected to the networkeven if part of the network infrastructureis down. The Summit X450a seriescontinuously checks for problems in theuplink connections using advanced Layer 3protocols such as OSPF, VRRP and ESRP(ESRP supported in Layer 2 or Layer 3),and dynamically routes traffic around theproblem.Voice-Grade Stacking withSummitStackThe Summit X450a series offers dualstacking interfaces to provide high-speed40 Gbps stacking bandwidth. SummitStackstacking architecture is designed tosupport converged services such as VoIPand video by its highly available, rapidfailover capability with n-1 masterredundancy, distributed Layer 2 andLayer 3 switching, link aggregation acrossthe stack and distributed uplinks.SummitStack supports up to eight units ina stack, and the mixture of the units canbe Summit X250e, Summit X450e,Summit X450a, Summit X480 andSummit X650 switches. It providessub-second failover for path failure andhitless master/backup failover along withhitless protocol support such as OSPFgraceful restart and Network Login userauthentication. The Summit X450aswitch provides chassis-like managementand availability with its SummitStackstacking technology (see Figure 2).Equal Cost MultipathHigh Availability NetworkProtocolsEthernet Automatic ProtectionSwitching (EAPS)EAPS allows the IP network to providethe level of resiliency and uptime thatusers expect from their traditional voicenetwork.

Extreme Networks Data SheetAdvanced Features Offer Versatile DeploymentCombining superior resiliency, comprehensive security, and nonblocking performance, the Summit X450a switch is thecornerstone of a high-performance network. Summit X450a series provides a high bandwidth, non-blocking architecturewith tri-speed copper Gigabit Ethernet ports for demanding Top-of-Rack data center applications. With optional 10 gigabittrunks, Summit X450a switches connect to gigabit edge devices and provide a high-performance aggregation layer in atraditional three-tier LAN. For Carrier Ethernet networks, Summit X450a switches deliver exceptional QoS and trafficmanagement capabilities.High Bandwidth, Non-BlockingArchitecture for DemandingEdge ApplicationsWhen deployed as an access switch,Summit X450a, with its modular 10gigabit integrated fiber gigabit ports,provides the bandwidth required by themost demanding applications. With morethan 20 gigabits of uplink capacity, uplinkbandwidth bottlenecks are eliminated.Providing line-rate throughput andsupporting jumbo frames up to 9,216bytes, Summit X450a allows transfers tobe completed in minimal time.High Density Gigabit Portswith Optional 10 GigabitUplinksThe Summit X450a switches provide idealperformance and functionalities for theaggregation layer. They eliminate the needto funnel traffic through a low bandwidthgigabit trunk by providing non-blocking 10gigabit links to the core. As an optionmodule, Summit X450a provides a varietyof choices for 10 Gigabit Ethernet uplinks:dual port 10GBASE-T for UTP connectivity,dual port SFP for fiber and passive copperconnectivity, dual port XFP and dual portXENPAK.Link Redundancy ProtocolsAggregation switches are located in thenetwork crossroads with high-densitytraffic from many users. Because of itslocation, every connection to and from anaggregation switch must be redundant inorder to allow a safe failover of traffic to asecondary path in case of link or devicefailure. The Summit X450a series offerssuperior link redundancy features thatprovide a highly available aggregation layer. 2010 Extreme Networks, Inc. All rights reserved.For example, where voice-grade resiliencyis required, EAPS allows links to failoverrapidly so that voice call sessions are notdropped. Other link resiliency featuresinclude OSPF, ECMP and VRRP, providingstandards-based Layer 3 dual homing,ESRP that offers dual homing at bothLayer 2 and Layer 3, and a unique softwareredundant port that does not require anyloop detection protocol and is easy toconfigure.Advanced Routing Capabilitiesfor Small Network CoreSupporting core deployments requires fullprotocol support. Summit X450a switchessupport advanced protocols for an efficientand productive small network core. Theswitches provide static, RIP and Edge-OSPFprotocols with policy-based routingcapabilities. An optional ExtremeXOS corelicense extends the feature set to includeother important core functions such as: Full OSPF for much greater extensibilitythan RIP can provide BGP for inter-autonomous systemforwarding PIM, sparse and dense modes forrouting of multicast streams IPv6 hardware forwarding withOSPFv3 IPv6 tunnels, IPv6-to-IPv4 translation,and IPv6 multicast discovery forextensive IPv6 supportExceptional Policy-Based QoSand Traffic Management forTriple Play ServicesThe Summit X450a series provides eighthardware queues per port to supportgranular traffic classification, and up to2,048 centralized ACLs per 24-port blockthat can use information from Layers 1 – 4to prioritize and meter incoming packets atline-rate. When metering traffic, the switchescan drop out-of-spec traffic or flag it forlater action. To expedite upstream traffichandling, a packet’s classification can becarried forward with Layer 2 (802.1p) andLayer 3 (DiffServ) markings. Summit X450aprovides advanced traffic managementfeatures that support the high quality tripleplay of voice, video and data services.Summit X450a switches supportExtreme Networks vMAN tag stackingmechanism, which is compliant with theIEEE 802.1ad Provider Bridges standard.vMAN allows service providers to aggregatesubscribers by using stacked Q-tags.Summit X450a switches provide lowlatency and hardware-based support formulticast traffic, making them excellentsolutions for IPTV deployment over CarrierEthernet infrastructures. The DC-poweredversion of Summit X450a switches providesan internal DC PSU and an optionalredundant PSU and can be deployed in aPOP where AC is not available.Summit X450a Series—Page 3

Extreme Networks Data SheetComprehensive SecurityImplementing a secure network means providing protection at the network perimeter as well as the core. Working together withExtreme Networks Sentriant family of products, Summit X450a switches use advanced security functions in protecting yournetwork from known or potential threats.User Authentication and HostIntegrity CheckingNetwork Login andDynamic Security ProfileSummit X450a series switches support acomprehensive range of Network Loginoptions by providing an 802.1x agentbased approach, a Web-based (agent-less)login capability, and a MAC-basedauthentication model. With these modesof Network Login, only authorized usersand devices can connect to the networkand be assigned to the appropriateVLAN. The Universal Port featureavailable in Summit X450a lets youimplement Dynamic Security Profileswith Network Login and allows you toimplement fine-grained and robustsecurity policies. Upon authentication,the switch can load dynamic ACL/QoSfor a user or group of users to deny/allowaccess to the application servers orsegments within the network.Multiple Supplicant SupportIdentity ManagementIdentity Management allows customers totrack users who access their network. Useridentity is captured based on NetLoginauthentication, LLDP discovery andKerberos snooping. ExtremeXOS uses theinformation to then report on the MAC,VLAN, computer hostname, and portlocation of the user.Host IntegrityHost integrity checking keeps infected ornon-compliant machines off the network.Summit X450a series support a host andendpoint integrity solution that is basedon a model promoted by the TrustedComputing Group by interfacing withExtreme Networks endpoint securityproduct, Sentriant AG.Threat Detection and ResponseCLEAR-Flow Security Rules EngineCLEAR-Flow Security Rules Engineprovides first order threat detection andmitigation, and mirrors traffic to appliancesfor further analysis of suspicious traffic inthe network.Converged network designs ofteninvolve the use of shared ports thatrepresent a potential vulnerability in anetwork. Multiple supplicant capabilitieson a switch allow it to uniquely recognizeand apply the appropriate policies foreach user or device on a shared port.sFlow is a sampling technology that providesthe ability to sample application level trafficflows on all interfaces simultaneously.MAC SecurityPort MirroringMAC security allows the lockdown of aport to a given MAC address and limitingthe number of MAC addresses on a port.This can be used to dedicate ports tospecific hosts or devices such as VoIPphones or printers, and avoid abuse ofthe port—an interesting capabilityspecifically in environments such ashotels. In addition, an aging timer can beconfigured for the MAC lockdown,protecting the network from the effectsof attacks using (often rapidly) changingMAC addresses.IP SecurityExtremeXOS IP security frameworkprotects the network infrastructure,network services such as DHCP andDNS, and host computers from spoofingand man-in-the-middle attacks. It alsoprotects the network from staticallyconfigured and/or spoofed IP addresses.It builds an external trusted database ofMAC/IP/port bindings so you knowwhere traffic from a specific addresscomes from for immediate defense.sFlowcally stop these packets from reaching theCPU. After a period of time, these ACLs areremoved and reinstalled if the attackcontinues. ASIC-based LPM routingeliminates the need for control planesoftware to learn new flows, allowing morenetwork resilience against DoS attacks.Secure and ComprehensiveNetwork ManagementAs the network becomes a foundation of theenterprise application, network managementbecomes an important piece of solution.Summit X450a supports comprehensivenetwork management through CommandLine Interface (CLI), SNMP v1, v2c, v3, andthe embedded XML-based web userinterface, ExtremeXOS ScreenPlay . Witha variety of management options andconsistency across other Extreme Networksmodular and stackable switches, Summit X450aseries switches provide ease-of-managementfor demanding converged applications.Extreme Networks has developed tools thathelp save you time and resources inmanaging your network. EPICenter management suite provides fault, configuration, accounting, performance and securityfunctions,allowing more effective management of Extreme Networks multi-layerswitching equipment in a converged network.To allow threat detection and prevention,Summit X450a switches support many-to-oneand one-to-many port mirroring. Thisallows the mirroring of traffic to an externalnetwork appliance such as an intrusiondetection device for trend analysis or forutilization by a network administrator fordiagnostic purposes. Port mirroring canalso be enabled across switches in a stack.Line-Rate ACLsACLs are one of the most powerfulcomponents used in controlling networkresource utilization as well as protectingthe network. The Summit X450a seriessupports up to 2,048 centralized ACLs per24-port block based on Layer 2, 3 or 4header information such as the MAC or IPsource/destination address.Denial of Service ProtectionSummit X450a effectively handles DoSattacks. If the switch detects an unusuallylarge number of packets in the CPU inputqueue, it will assemble ACLs that automati-Figure 3: Automated Attack Mitigation 2010 Extreme Networks, Inc.
