Huawei CloudEngine S6720‑54C‑EI‑48S‑AC Full English Product Description

Huawei CloudEngine S6720‑54C‑EI‑48S‑AC is a high‑density enhanced‑version 10GE all‑optical full‑Layer‑3 managed switch of S6720‑EI series, running on Huawei mature VRP (Versatile Routing Platform) operating system. It is equipped with 48×10GE SFP+ multi‑rate optical downlink ports, 2×40GE QSFP+ fixed uplink ports and one independent service expansion slot for flexible port extension. This AC‑powered model adopts dual hot‑swappable modular power‑supply slots supporting 1+1 power redundancy with AC power modulesAlibaba.co.... PoE function is not supported. Compared with LI‑series models, the EI version features larger hardware buffer, comprehensive enterprise‑grade service features and improved system reliability. It can be deployed as aggregation or small‑core device for enterprise campus, high‑density all‑optical networks, metropolitan‑network convergence, and small‑to‑medium‑size data‑center top‑of‑rack access scenarios.

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. 2×40GE QSFP+ ports support high‑bandwidth uplink, iStack hardware stacking, and can be split into four 10GE interfaces. One independent service expansion slot accepts optional sub‑cards to further expand uplink bandwidth and stacking capacityAlibaba.co.... Dual hot‑swappable modular power‑supply slots support 1+1 redundancy, compatible with 100‑240V AC power modules. Hot‑swappable fan modules adopt front‑to‑back airflow; intelligent variable‑speed fans dynamically adjust rotation speed to balance heat dissipation and acoustic noise. PoE power supply is not supported. Both power and fan modules support hot‑swap without interrupting running services. Equipped with Console port, Mini‑USB console, ETH management port and USB port for convenient device maintenance. Standard 19‑inch 1U rack‑mount chassis for cabinet installation.
Rich Layer‑2 Functions

Supports 4094 IEEE 802.1Q VLANs, MUX VLAN, Voice VLAN, Guest VLAN, GVRP, basic & flexible QinQ and VLAN mapping. Implements STP/RSTP/MSTP, Smart‑Link, RRPP and ERPS 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 network devices.
Full Layer‑3 and IPv6 Functions

Supports static routing, RIP, OSPF, IS‑IS, BGP, OSPFv3, BGP4+, VRRP, ECMP equal‑cost routing, as well as mature multicast protocols including PIM‑DM, PIM‑SM, PIM‑SSM and MSDP. Complete IPv4/IPv6 dual‑stack capability covers ND, Ping, Tracert, IPv6 ACL and IPv6‑related tunnel technologies. Supports policy‑based routing and URPF feature. Delivers abundant MPLS functions including MPLS‑L3VPN, VPWS and VPLS for enterprise and metropolitan‑network service bearing. Large‑capacity hardware buffer handles burst traffic for campus and data‑center scenarios. MAC address table supports large‑scale forwarding capacity.
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.
Powerful QoS and Intelligent O&M Capabilities

8 priority queues per port, supporting SP / WRR / DRR / SP+WRR 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, RMON and sFlow traffic sampling. 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.
Hardware Design

Hot‑swappable fan modules with front‑to‑back airflow; dual hot‑swap modular power‑supply slots supporting 1+1 AC redundancy. Standard 19‑inch 1U rack‑mountable chassis.
