The NetVanta 1000 Series from ADTRAN is a standards-based, non-blocking Layer 2 switching solution available at a cost up to 50 percent less than competing switches. These devices are suitable for converged LAN/WAN access, interconnecting LAN devices, or for network segmentation. The NetVanta 1224STR is a unique, all-in-one access platform that combine a 24-port Ethernet switch, an IP access router, a modular WAN interface with built-in NTU, a stateful inspection firewall, and the option for Virtual Private Networking (VPN), all in a single 1U chassis. The 1224STR provides 24-port Ethernet and Fast Ethernet switching, offering an extra 1000Base-T/SFP Gigabit port for uplink or stacking capability.Based on the ADTRAN Operating System (AOS), this device offers support for 802.1Q Virtual LANs (VLANs), port-based switching features include Broadcast Storm Control, 802.1D and 802.1w Spanning/Rapid Spanning Tree, Link Aggregation, Port Mirroring, and GVRP. Link Layer Discovery Protocol (LLDP) auto-discovers neighboring Ethernet devices, simplifying integration into multi-vendor environments.Rest assured, with the NetVanta 1224STR your network is protected. The platform comes standard with a stateful inspection firewall to stop intruders and common Denial of Service (Dos) attacks. The product also offers a variety of data security features including MAC-based port security, multilevel user passwords, Secure Shell (SSH) and Secure Socket Layer (SSL) for encrypted user login, and Access Authentication and Authorization (AAA) for authentication with a RADIUS or RSA SecurID server. For added security, this platform offers a VPN upgrade supporting up to 500 IPSec tunnels using DES, 3DES or AES encryption.This switch-router supports QoS to prioritize mission critical traffic and control network congestion at various layers of the OSI model. On the LAN, the NetVanta 1000 Series offers 802.1p and DiffServ Class of Service (CoS). To assign priority to traffic, Weighted Round Robin and Strict Priority Queuing is used with four egress queues per port. For the WAN, DiffServ marking, Low Latency Queuing, and Weighted Fair Queuing provide priority for IP packets routed over the WAN. Together these features offer a powerful end-to-end QoS story.
