Huawei S3700-28TP-SI-DC – Product Documentation

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

Product Overview

The Huawei S3700-28TP-SI-DC is a next-generation, energy‑efficient Layer 3 Fast Ethernet switch designed for enterprise campus networks. It belongs to the Huawei Quidway S3700 series and provides a cost‑effective, reliable, and secure switching solution for small‑ to medium‑sized businesses and enterprise branch offices.

The switch features 28 fixed ports, comprising 24 x 10/100Base‑TX ports, 2 x 1000Base‑X SFP ports, and 2 x Gigabit Combo ports (10/100/1000Base‑T or 100/1000Base‑X). It is powered by a DC power supply (-48V to -60V), making it suitable for data center and telecom environments where DC power is standard.

With a switching capacity of 64 Gbps and a forwarding performance of 9.6 Mpps, the S3700-28TP-SI-DC delivers robust wire‑speed performance for 10/100 Mbps networks. It supports advanced Layer 3 routing features including static routing, RIPv1, RIPv2, and ECMP, as well as IPv6 transition technologies such as 6to4 and ISATAP tunnels, ensuring a smooth migration path to next‑generation IP networks.

The switch incorporates comprehensive VLAN capabilities (supporting up to 4K VLANs), sophisticated QoS with 8 priority queues per port, and multi‑level security features including 802.1X authentication, ACLs, and anti‑DoS protection. It also supports industry‑standard reliability protocols such as RRPP, Smart Link, and STP/RSTP/MSTP, with millisecond‑level protection switchover.

The S3700-28TP-SI-DC is fully managed via SNMP, Telnet, SSH, and web‑based interfaces, and supports features such as port mirroring, RSPAN, and remote configuration, enabling efficient network operations and maintenance.
