Layer 3 Lite Gigabit Ethernet Switch


Sorry, this product is no longer available, Please contact us for a replacement.



NetVanta® 1531 is a managed, 12-port, Layer 3 Lite, Gigabit Ethernet switch designed as an access layer switch for small businesses and branch office deployments. With the combination of the advanced multi-layer switching fabric, high-bandwidth capabilities, and enhanced QoS features, the NetVanta 1531 is ideal for Voice over IP (VoIP), Gigabit-to-the-desktop and converged voice and data deployments. Experience ease of management with Web-based Graphical User Interface (GUI) and familiar Command Line Interface (CLI).


The NetVanta 1531 is a desktop, wall mountable or rack mountable switch with a fanless design ensuring quiet operation. It provides 12 Gigabit Ethernet ports, consisting of 10 fixed 10/100/1000Base-T Ethernet ports and two 1.0 Gbps SFP ports. With two interconnected NetVanta 1531 switches mounted in a 19-inch rack (using the optional dual mounting tray), you can scale to twenty GigE ports, and up to four Gbps of backplane capacity, when using the SFP ports.

Multi-layer Switching

The NetVanta 1531 supports advanced multi-layer (Layer 2 and Layer 3 Lite) switching with up to 16 static routes allowing it to easily scale from SMBs to enterprise-size networks.

VoIP Ready

The NetVanta 1531 is VoIP-ready with the ability to automatically configure IP phones using LLDP-MED, and the ability to separate voice traffic onto voice VLANs, to simplify the deployment of VoIP. In addition, the switch includes a VoIP Setup Wizard (available via a web-based GUI or CLI), which automates the complete VoIP setup process reducing deployment time and eliminating errors. An on-demand VoIP report provides a printable summary of the switch VoIP configuration, as well as providing alerts and recommendations to improve performance. All NetVanta switches support QoS to prioritize VoIP traffic, 802.1p and DiffServ Class of Service (CoS).


The NetVanta 1531 offers a variety of data security features including DoS protection, 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 RADIUS and TACACS+. With features such as 802.1x and port security, administrators can assure that only authorized users are allowed access to the network.

The ADTRAN® Operating System (AOS) also features desktop auditing using DHCP in conjunction with Microsoft Network Access Protection (NAP) protocol to monitor the health of client computers. The two protocols work together to ensure that systems connected to the network are using appropriate corporate policies, such as firewall settings, antivirus settings and other client health information.

Port Scheduler

NetVanta 1531 allows ports to be enabled or disabled based on time of day. This ability to schedule available ports allows for added security and can provide less power consumption during off hours, saving on utility cost.

iSCSI Optimized

All ADTRAN NetVanta Gigabit Ethernet switches are optimized for iSCSI SAN deployments. Network administrators can take advantage of features such as Jumbo frame support (up to 9K), separation of iSCSI network traffic utilizing VLANs, and 802.3x flow control to seamlessly integrate ADTRAN switches with iSCSI SANs devices.


AOS offers both a CLI and an intuitive Web-based GUI with step-by-step configuration wizards. For automating setup and configuration, NetVanta 1531 supports Auto-Config which provides the ability to automatically obtain the switch configuration via DHCP.

AOS also offers network forensics to aid in troubleshooting network problems by allowing network administrators to easily locate devices on the network by MAC or IP address.
