Huawei S2720-28TP-EI-AC Product Documentation

Name: Huawei S2720-28TP-EI-AC Switch - SunSpike
SKU: S2720-28TP-EI-AC

Product Overview

The Huawei S2720-28TP-EI-AC is a next-generation access switch that provides flexible 100M and GE access ports along with GE uplink ports. Built on next-generation, high-performance hardware and the Huawei Versatile Routing Platform (VRP), this switch supports intelligent stacking (iStack), flexible Ethernet networking, and diversified security control. It delivers a green, easy-to-manage, easily expandable, and cost-effective 100M-to-desktop solution for enterprise and small-to-medium business networks.

The switch operates at Layer 2 with a store-and-forward switching architecture, featuring 28 ports in a non-modular design. It includes 24 10/100BASE-TX Ethernet ports, 4 Gigabit SFP ports, and 2 combo ports (10/100/1000BASE-T + 100/1000BASE-X). With a backplane bandwidth of 12.8 Gbps and a packet forwarding rate of 9.6 Mpps, it provides reliable performance for desktop access scenarios.

The S2720-28TP-EI-AC offers comprehensive features including VLAN support (IEEE 802.1Q with up to 4K VLANs), QoS with 8 priority queues per port, multicast management (IGMP snooping v1/v2/v3), and robust security capabilities such as AAA authentication, 802.1X认证, MAC authentication, DHCP Snooping, and port isolation. It also supports IPv6 protocols, static routing, and MLD snooping.

With a compact 1U form factor (43.6 mm × 442.0 mm × 220.0 mm), fanless design for silent operation, and built-in surge protection (7KV on service ports), this switch is ideal for deployment in enterprise wiring closets and branch offices requiring reliable, quiet, and energy-efficient networking.
