Huawei CloudEngine S6720‑48S‑LI Full English Product Description

Product Overview

Key Features

1. Port and Hardware Configuration

   48×10GE SFP+ multi‑rate optical slots support GE /10GE SFP/SFP+ transceivers, DAC high‑speed cables and AOC active optical cables for high‑density optical access. No independent service expansion slot. Any 10GE SFP+ port can serve as iStack stacking port. Built‑in fixed AC power supply, with RPS redundant power input interface. Adopts intelligent variable‑speed fixed fan module to balance heat dissipation and acoustic noise. PoE power supply is not supported. Equipped with Console port, Mini‑USB console, ETH management port and USB port for convenient device maintenance. Compact short‑depth design, standard 19‑inch 1U rack‑mount chassis for shallow‑depth cabinet installation华为企业业....
2. Rich Layer‑2 Functions

   Supports 4094 IEEE 802.1Q VLANs, MUX VLAN, Voice VLAN, Guest VLAN, GVRP, basic QinQ and VLAN mapping. Implements STP/RSTP/MSTP, Smart‑Link and RRPP ring‑protection protocols for millisecond‑level link fail‑over recovery. Supports LACP link aggregation, IGMP Snooping v1/v2/v3, MLD Snooping, broadcast‑multicast‑unicast storm suppression and port isolation. iStack hardware stacking combines multiple physical switches into one logical device for unified configuration and management. SVF super virtual fabric simplifies campus network architecture and reduces deployment and O&M workloads. Supports VBST protocol for seamless inter‑operation with PVST+ compatible third‑party devices华为企业业....
3. Basic Layer‑3 and IPv6 Functions

   Supports static routing, RIP, OSPF, OSPFv3, VRRP and ECMP equal‑cost routing. Supports multicast protocols including PIM‑DM, PIM‑SM and PIM‑SSM. Complete IPv4/IPv6 dual‑stack covers ND, Ping, Tracert, IPv6 ACL and IPv6 QoS. MAC address table supports up to 32K entries for medium‑scale high‑speed traffic forwarding.
4. Comprehensive Security Mechanism

   Supports 802.1X authentication, MAC‑based authentication, Portal authentication, AAA / RADIUS / HWTACACS access control. Provides DHCP Snooping, ARP anti‑attack, DoS‑attack defense, BPDU protection, root‑protection and MAC‑address‑learning‑limit control. L2‑L4 ACL realizes flexible traffic filtering based on MAC address, IP address, port number and protocol type. Supports SSHv2 and HTTPS for secure encrypted management access.
5. Powerful QoS and Intelligent O&M Capabilities

   8 priority queues per port, supporting SP / WRR / DRR queue‑scheduling algorithms. Supports port‑based rate‑limiting, two‑rate three‑color CAR, 802.1p / DSCP remarking and traffic shaping. Provides Console port, Mini‑USB console, Web‑GUI, Telnet, SSH, SNMP v1/v2c/v3 and RMON. Compatible with eSight and iMaster NCE‑Campus management platforms. Supports PNP zero‑touch deployment, VCT virtual‑cable‑test and Ethernet OAM for quick fault diagnosis. Supports EEE energy‑efficient Ethernet for low‑power‑consumption operation.
6. Hardware Design

   Intelligent variable‑speed fan cooling; built‑in fixed AC power with RPS redundant power interface. Compact short‑depth, standard 19‑inch 1U rack‑mountable chassis.
