Huawei S3700-28TP-SI-AC Switch – Product Documentation

Name: Huawei S3700-28TP-SI-AC Switch - SunSpike
SKU: S3700-28TP-SI-AC

Product Overview

The Huawei S3700-28TP-SI-AC is a next-generation, energy‑efficient Layer 3 fast Ethernet switch developed for enterprise campus networks. Built on Huawei’s Versatile Routing Platform (VRP) software and powered by high‑performance hardware, it delivers a robust combination of switching, routing, and security features tailored for aggregation and access layer deployments in medium‑sized enterprise environments.

The switch provides both Layer 2 functionality and basic Layer 3 IP routing capabilities, including support for static routes, RIPv1, RIPv2, and ECMP (Equal‑Cost Multi‑Path) routing. With its compact 1U form factor and fan‑less design, the S3700-28TP-SI-AC enables silent operation and flexible installation options including rack mounting, desk mounting, and wall mounting.

A key feature of this switch is its support for Huawei’s Intelligent Stacking (iStack) technology, which allows multiple S3700 switches to be interconnected via service ports to form a single logical virtual switch, simplifying network management and enhancing scalability. The device also supports IPv4/IPv6 dual stack, ensuring smooth transition to next‑generation networks.

Equipped with comprehensive security mechanisms, the S3700-28TP-SI-AC defends against DoS attacks (including SYN Flood, Land, Smurf, and ICMP Flood), ARP spoofing, and ICMP attacks. It supports 802.1X authentication, AAA, RADIUS, HWTACACS+, NAC, and SSH V2.0 for secure remote management. The switch also offers granular QoS controls with eight priority queues per port and supports multiple queue scheduling algorithms including WRR, DRR, SP, WRRSP, and DRR+SP.
