LT-GS3428FC 24+4 Port Gigabit L2+ Managed Switch
The LT-GS3428FC is a full‑Gigabit Layer 2+ managed switch developed by NEWBRIDGE for enterprises, campuses, hotels, and SMB networks. It features 24× 10/100/1000Mbps RJ45 ports and 4× Gigabit Combo ports (each Combo port can be used as either RJ45 or SFP) – all 28 ports support non‑blocking wire‑speed forwarding.
This switch offers advanced L2+ features including static routing (IPv4/IPv6), IEEE 802.1Q VLAN (port‑based, protocol‑based, MAC‑based, Voice VLAN, Surveillance VLAN), QoS (8 queues/port, WRR/WFQ/SP scheduling), ACL (L2/L3/L4, up to 1024 rules), IGMP Snooping v1/v2/v3, MLD Snooping, LACP link aggregation, STP/RSTP/MSTP (16 instances), ERPS, port isolation, DHCP Snooping, DoS prevention, and comprehensive security. Management interfaces include Web GUI (HTTP/HTTPS), CLI (Console/Telnet/SSH v1/v2) , and SNMP v1/v2c/v3.
Housed in a fanless metal 19-inch case (440×290×44.5mm), it operates from 0℃ to 45℃. Ideal for network access and aggregation layers, this switch provides cost-effective, high-performance L2+ management without PoE.

QoS – 8 queues/port, scheduling (WRR, WFQ, Strict Priority, Hybrid), priority based on port/802.1p/DSCP, rate limiting.
ACL – L2/L3/L4, MAC‑based (512), IPv4/IPv6‑based, up to 1024 rules.
Multicast – IGMP Snooping v1/v2/v3 (256 groups), IGMP querier, MLD Snooping v1/v2, MVR (IPv4).
🔄 Ring Redundancy & High Reliability
STP, RSTP, MSTP (16 instances), ERPS, self‑loop detection – fast failover (<50ms).
IEEE 802.3ad LACP and static trunk (max 8 groups, 8 ports/group) with load balancing.
🛡️ Comprehensive Security
802.1X (port‑based/host‑based), MAC authentication, Web authentication, Guest VLAN.
