Huawei S5720I‑28P‑SI‑AC Full English Product Description

Product Overview

Key Features

1. Port Configuration

   24×10/100/1000BASE‑T copper ports for gigabit device access; 4 dedicated GE SFP slots accept GE SFP optical transceivers for long‑distance fiber uplink. PoE function is not supported. Equipped with dual hot‑swappable power slots, supports 1+1 power redundancy for high‑reliability industrial networking.
2. Rich Layer‑2 Functions

   Supports 4094 IEEE 802.1Q VLANs, MUX VLAN, Voice VLAN, Guest VLAN, GVRP and VLAN mapping. Implements STP/RSTP/MSTP, Smart‑Link, RRPP ring‑protection for millisecond‑level link fail‑over. Supports LACP link aggregation, IGMP Snooping v1/v2/v3, MLD Snooping, broadcast/multicast/unicast storm suppression and port isolation. iStack hardware stacking consolidates multiple physical switches into one logical unit for unified management.
3. Advanced Layer‑3 & IPv6 Dual‑Stack Functions

   Supports static routing, RIP, OSPF, OSPFv3, IS‑IS, BGP, VRRP, VRRPv3 and ECMP equal‑cost routing. Full IPv4/IPv6 dual‑stack capability includes ND, Ping, Tracert, IPv6 ACL and IPv6 QoS, satisfying complex multi‑service routing requirements for industrial and enterprise networks.
4. Industrial‑grade Security & Surge Protection

   Supports 802.1X, MAC‑based authentication, AAA/RADIUS/HWTACACS, port security, DHCP Snooping, anti‑ARP‑attack and anti‑DoS protection. L2‑L4 ACL implements flexible traffic filtering; SSHv2 guarantees secure management access. Service ports provide high‑level common‑mode surge protection to resist industrial electromagnetic interference.
5. Powerful QoS and O&M Capabilities

   8 priority queues per port, supporting SP / WRR / WFQ / SP+WRR scheduling algorithms. Supports port‑based rate‑limiting, two‑rate three‑color CAR, 802.1p / DSCP remarking. Supports Console CLI, Mini‑USB console, Web‑GUI, Telnet, SSH, SNMP v1/v2c/v3, RMON, sFlow, virtual cable test, compatible with eSight network management system. Supports SVF super virtual fabric function.
6. Hardware & Industrial‑grade Design

   Intelligent temperature‑adjustable forced‑air fan cooling; hot‑swappable dual‑power slots support AC power 1+1 redundancy. Wide operating temperature range adapts to harsh workshop, cabinet and outdoor‑cabinet environments. Standard 19‑inch 1U rack‑mountable chassis. Adopts EEE energy‑saving Ethernet technology.
