Huawei CloudEngine S5755‑H48Q8C Full English Product Description

Product Overview

Key Features

1. Port and Hardware Configuration

   48×100M/1G/2.5GE SFP multi‑rate optical slots support FE/GE/2.5G optical transceivers for high‑density all‑optical downlink access. 8×40GE/100GE QSFP28 high‑speed ports are available for high‑bandwidth uplink or iStack hardware stacking connection. One independent service expansion slot supports optional service cards to expand uplink bandwidth and stacking capacity. Dual hot‑swap modular power slots implement 1+1 power redundancy, compatible with AC, high‑voltage‑DC and ‑48V DC power modules. Hot‑swappable fan modules adopt front‑to‑back airflow; intelligent variable‑speed fan dynamically adjusts rotation speed to balance heat dissipation and acoustic noise. PoE power supply is not supported. Power and fan modules support hot‑swap without interrupting running services.
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 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 consolidates 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 interoperation with PVST+ compatible devices.
3. Full Layer‑3, IPv6 and Virtualization Functions

   Supports static routing, RIP, OSPF, OSPFv3, 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 covers ND, Ping, Tracert, IPv6 ACL and IPv6 QoS. Supports VXLAN network virtualization with L2/L3 gateway and BGP‑EVPN capability, realizing multi‑service bearing for campus networks. Service Free‑Mobility ensures consistent user access policy across whole network. MAC address table supports up to 256K entries for large‑scale forwarding capacity华为企业业....
4. Comprehensive Security Mechanism

   Supports 802.1X authentication, MAC‑based authentication, Portal authentication, AAA / RADIUS / HWTACACS and NAC access control. All ports support MACsec for end‑to‑end link encryption to enhance transmission security华为企业业.... Provides DHCP Snooping, ARP anti‑attack, DoS‑attack defense, black‑hole MAC entries and MAC‑address‑learning‑limit control. L2‑L4 ACL realizes flexible traffic filtering; SSHv2 and HTTPS guarantee secure encrypted management access.
5. Powerful QoS and Intelligent O&M Capabilities

   8 priority queues per port, supporting SP / WRR / WFQ / SP+WRR queue‑scheduling algorithms. Supports port‑based rate‑limiting, two‑rate three‑color CAR, 802.1p / DSCP remarking. Provides Console port, Mini‑USB console, Web‑GUI, Telnet, SSH, SNMP v1/v2c/v3, RMON, NetStream traffic sampling and Telemetry real‑time data collection. iPCA supports real‑time service‑quality monitoring and packet‑loss diagnosis. Compatible with eSight and iMaster NCE‑Campus network‑management platforms. Supports PNP zero‑touch deployment to lower on‑site maintenance complexity. Supports EEE energy‑efficient Ethernet for low‑power‑consumption operation.
6. Hardware Design

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