The NetVanta ® 1000 Series of managed,Layer 2, Ethernet switches is designed forfast, secure, cost-effective LAN switching.These scalable, full-featured business-classswitches are perfect for VoIP applications byusing robust Quality of Service (QoS) featuresand Power over Ethernet (PoE) capabilities topower IP Phones, protecting the organizationwith advanced security capabilities, and easeof management with an easy to use Web-GUIand familiar Command Line Interface (CLI).HardwareThe NetVanta 1234 and 1238 rackmountswitches support 24 and 48 10/100Base-TEthernet ports with auto-rate, auto-duplexing,and MDI/MDI-X sensing. The NetVanta 1234/1238 also supports four Gigabit ports foruplink or stacking capability.Standard-based ProtocolsBased on the ADTRAN ® Operating System(AOS), these devices offer support for LinkAggregation (802.3ad), Port Mirroring, Port-based switching features including BroadcastStorm Control, Spanning Tree (802.1D) andRapid Spanning Tree (802.1w) for fasternetwork convergence, link redundancy, andrecovery from topology changes. Link LayerDiscovery Protocol (LLDP) auto-discoversneighboring Ethernet devices, simplifyingintegration into multi-vendor environments.VLANsAll NetVanta switches support 802.1Qtrunking and up to 255 port-based VLANsto allow network managers to separatebroadcast domains for efficient networkperformance and traffic control.PoEThe NetVanta 1234 PoE and 1238 PoE plat-forms provide standards-based 802.3af andLegacy PoE functionality for powering IPphones, Wireless Access Points (WAPs), orother devices requiring LAN power.SecurityRest assured, with the NetVanta 1234 and1238 PoE your network is protected. Theseproducts also offer a variety of data securityfeatures including multilevel user passwords,Secure Shell (SSH) and Secure Socket Layer(SSL) for encrypted user login, and AccessAuthentication and Authorization (AAA)for authentication with a RADIUS, RSASecurID and TACACS+.Quality of Service (QoS)NetVanta switches also support QoS toensure network managers have the ability toprioritize mission critical traffic like VoIP andcontrol network congestion. The NetVanta1000 Series offers 802.1p and DiffServ Classof Service (CoS). Each switch supports frametagging, as well as enforcement of taggedtraffic received from trusted sources. Fouregress queues (per port) are available forassigning traffic priorities using WeightedRound Robin (WRR).AdministrationThe AOS offers both a Command LineInterface (CLI) that mimics the widelydeployed, industry de facto standard and anintuitive web-based GUI with step-by-stepconfiguration wizards. For a 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 ADTRANproducts including access routers, WirelessAccess Points, IP Business Gateways, IPphones, and VoIP telephony solutions. Allthese solutions are backed by ADTRAN’sindustry-leading support, services, andindustry-leading warranty.Product Featuresn 24/48-port auto-sensing10/100Base-T managedLayer 2 Ethernet switchn 4 Gigabit uplink portsn 802.3af and Legacy Powerover Ethernetn Non-blocking, up to 17.6 Gbpsswitching capacityn 802.1Q tagged and port-based Virtual Local AreaNetworks (VLANs)n Support for up to 255active VLANsn 802.1p and DiffServprioritization with fourqueues per egress portn Link aggregation, LLDP andLLDP-MEDn Weighted Round Robin (WRR)and WRR + expediten 802.1D Spanning Tree and802.1w Rapid SpanningTree supportn DHCP address managementn RADIUS authenticationn Port mirroringn TFTP/FTP firmware upgradesn Broadcast, Unicast, andMulticast storm controln Wi-Fi® Access Controller forcentralized management ofNetVanta Wireless AccessPoints (WAPs)n Cable diagnostics identifiescable length and detectsshorts or open twisted pairn Familiar Command LineInterface (CLI)n Web-based GraphicalUser Interface (GUI)n Limited Lifetime WarrantyNetVanta 1234/1238 PoEPower over Ethernet, Layer 2 Fast Ethernet SwitchesSmart Solutions for aConnected World.
