LT-GS3226F24+2 Port Gigabit L2 Managed Switch

The LT-GS3226F is a full‑Gigabit Layer 2 managed switch developed by NEWBRIDGE for campus, hotel, business park, and enterprise networks. It features 24× 10/100/1000Mbps RJ45 ports and 2× 1000Mbps SFP slots – all ports support non‑blocking wire‑speed forwarding.

This switch offers a comprehensive L2 management suite: Intelligent Auto-Configuration, Topology Graphic Display, quad binding (IP/MAC/Port/VLAN), ARP/IP/DoS protection, 802.1X Authentication, VLAN (802.1Q, port‑based, protocol‑based, MAC‑based, Voice/Surveillance VLAN), QoS (8 queues/port, WRR/WFQ/SP), ACL (L2/L3/L4, up to 1024 rules), IGMP Snooping v1/v2/v3, MLD Snooping, LACP Link Aggregation, STP/RSTP/MSTP (16 instances), ERPS, static routing (IPv4/IPv6), 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 case (440×192×45mm) with operating temperature (0℃～45℃) and support for guide rail/wall mount, it is ideal for cost-effective, reliable network access and aggregation in SMB and enterprise environments.
