All-in-One Network Access: Modular WAN Interface, Firewall, Ethernet Switch, IP Router, and Optional VPN

NetVanta® 1544F is a managed, 28-port, Layer 3, Gigabit Ethernet switch designed as an access layer or network backbone switch for small to medium-sized businesses. With the combination of the advanced multi-layer switching fabric, highbandwidth capabilities, and enhanced Quality of Service (QoS) features, the NetVanta 1544F is ideal as an aggregation switch for high-bandwidth Voice over IP (VoIP), and converged voice and data networks.


The NetVanta 1544F rackmount switch provides 28 Gigabit Ethernet ports, consisting of 24 standard 1 Gbps Small Form-factor Pluggable (SFP) Ethernet ports and four enhanced 2.5 Gbps SFP ports. The enhanced SFP ports support standard 1 Gbps up to 2.5 Gbps data rates. Together the four enhanced SFP ports can provide up to 20 Gbps of bi-directional bandwidth between interconnected NetVanta 1544 switches.

Multi-layer Switching

The NetVanta 1544F supports advanced multi-layer (Layer 2 and Layer 3) switching. It supports static routes, RIP V1/V2, OSPF, Border Gateway Protocol (BGP) and Virtual Router Redundancy Protocol (VRRP), allowing it to easily scale from small and medium-sized businesses to enterprise-sized customers

Standards Protocols

Based on the ADTRAN® Operating System (AOS), this device offers support for Link Aggregation (802.3ad); Port Mirroring; port-based switching features including Broadcast Storm Control, Spanning Tree (802.1D) and Rapid Spanning Tree (802.1w) for faster network convergence, link redundancy, and recovery from topology changes. Link Layer Discovery Protocol (LLDP) autodiscovers neighboring Ethernet devices, simplifying integration into multi-vendor environments.

Virtual LANs (VLANs)

All NetVanta switches support 802.1Q trunking and up to 255 VLANs to allow network managers to separate broadcast domains for efficient network performance and traffic control. NetVanta 1544F also supports dynamic VLANs assigned via 802.1x. This is an ideal way to make sure users are automatically assigned to the correct VLAN, based on the login. Private VLANs are also available to provide extra security by isolating upstream traffic from user ports.

VoIP Ready

NetVanta 1544F has been designed specifically for VoIP. The ability to automatically configure IP phones using LLDP-MED, and the ability to separate voice traffic onto voice VLANs, helps ease the deployment of VoIP

Quality of Service

NetVanta switches also support QoS to prioritize mission-critical traffic like VoIP and control network congestion. NetVanta 1544F offers 802.1p and DiffServ Class of Service (CoS). It also supports frame tagging, as well as enforcement of tagged traffic received from trusted sources. Four egress queues (per port) are available for assigning traffic priorities using Weighted Round Robin (WRR) and Strict Priority Scheduling.


Rest assured, with NetVanta 1544F your network is protected. This product 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 RADIUS, RSA SecurID and TACACS+. With features such as 802.1x and port security, administrators can assure that only authorized users are allowed access to the network.

Port Scheduler

NetVanta 1544F allows ports to be scheduled, or turned on or off based on time of day. This ability to schedule available ports allows for added security


AOS offers both a CLI that mimics the widely deployed, industry de facto standard and an intuitive Web-based GUI with step-by-step configuration wizards. For automating setup and configuration, NetVanta 1544F also supports features like Auto-Provisioning which allows automatic configuration scripts to be run from the integrated CompactFlash slot and Auto-Config which provides the ability to automatically obtain the switch configuration via DHCP
