Key Features & Benefits
Core Layer 3 Routing Intelligence
With full support for IPv4/IPv6 static and dynamic routing (RIP, OSPF, RIPng, OSPFv3), the FNS420-424TF4 is capable of functioning as a network core, efficiently directing traffic across complex topologies.
High Port Density with 10G Optical Uplinks
-4 x 10G SFP+ ports provide high-speed uplinks for aggregation and redundancy.
-24 x Gigabit RJ45 ports ensure stable, high-capacity data transmission across access-level devices.
-Optional PoE support allows seamless power delivery to edge devices like cameras or sensors.
Advanced Network Resiliency
-Redundancy protocols including STP, RSTP, MSTP, and ERPS (self-healing <20ms) protect against link failures.
-Storm control, flow control (802.3x), and IGMP Snooping v1/v2/v3 maintain network stability even under heavy traffic loads.
VLAN & QoS for Traffic Optimization
-Supports IEEE 802.1Q VLAN tagging, isolating traffic across departments or devices.
-Full QoS stack with IEEE 802.1p, ToS/DiffServ, COS/DSCP, and WRR/SP scheduling ensures high-priority traffic is always delivered first.
-Up to 4 traffic queues for advanced traffic shaping.
Security & Access Control
-ACLs, 802.1X authentication, and user classification protect against unauthorized access.
-SNMPv1/v2/v3 with encrypted communication and management via Web GUI or CLI provides flexible and secure device control.
Precise Time Synchronization
Built-in support for PTP (IEEE 1588v2) enables microsecond-level time sync—ideal for power grids, industrial automation, and telecom networks.
