Ideal for newinstallations or network upgrades, theseswitches can provide higher bandwidthfor corporate and branch office Local AreaNetworks (LANs) to support today’s mostbandwidth intensive applications.HardwareThe NetVanta 1524ST rackmount switchprovides 24 Gigabit Ethernet ports, consistingof 20 fixed 10/100/1000Base-T Ethernetports and four combo 10/100/1000Base-T/Small Form-factor Pluggable (SFP) ports.The 10/100/1000Base-T ports provideauto-rate, auto-duplexing, and auto-MDI/MDI-X sensing. The SFP slots are availableto accommodate optical interfaces usingindustry-standard SFP modules. The 1524STcan support up to 16 units stacked togetherand is easily managed with a single IPaddress for the entire stack.Standards ProtocolsBased on the ADTRAN Operating System(AOS), these devices offer support for LinkAggregation (802.3ad), Port Mirroring, port-based switching features including StormControl, Spanning Tree (802.1D) and RapidSpanning Tree (802.1w) for faster networkconvergence, link redundancy, and recoveryfrom topology changes. Link Layer DiscoveryProtocol (LLDP) auto-discovers neighboringEthernet devices, simplifying integration intomulti-vendor environments.VLANsAll NetVanta switches support 802.1Qtrunking and up to 255 port-basedVLANs to allow network managers toseparate broadcast domains for efficientnetwork performance and traffic control.To help aid configuration in larger networks,Generic VLAN Registration Protocol (GVRP)is also available.SecurityRest assured, with the NetVanta 1524ST yournetwork is protected. These products offera variety of data security features includingMAC-based port security, multilevel userpasswords, Secure Shell (SSH) and SecureSocket Layer (SSL) for encrypted user login,and Access Authenthication and Authorization(AAA) for authentication with RADIUS, RSASecurID, and TACACS+.QoSNetVanta switches also support QoS toensure network managers have the abilityto prioritize mission-critical traffic and controlnetwork congestion. The NetVanta 1524SToffers 802.1p Class of Service (CoS). Eachswitch supports frame tagging as well asenforcement of tagged traffic received fromtrusted sources. Two egress queues (per port)are available for assigning traffic prioritiesusing Strict Priority Queuing.AdministrationThe AOS offers both a CLI that mimics thewidely deployed, industry de facto standardand an intuitive Web-based GUI with step-by-step configuration wizards. For centralizedenterprise-wide management scheme,ADTRAN offers n-Command, an intuitive,scalable software suite for managing firm-ware revisions, push firmware upgrades andconfiguration changes, backup and restoreconfigurations, and manage security policiesand Access Control Lists (ACLs).NetVanta 1000 Series of Ethernet switchesare easily coupled with other ADTRAN inter-networking products including switch-routers,access routers, and multiservice access routers.All these solutions are backed by ADTRAN’sindustry-leading support and services.GlobalInternationalwww.adtran.com/global
