Huawei CloudEngine S9712 Modular Terabit‑Class Core Routing Switch

Product Overview

Key Features

• Modular high‑capacity hardware architecture: 15U standard 19‑inch rack‑mount chassis, 12 LPU service slots, dual‑MPU main‑control boards for 1+1 master‑backup redundancy. Hot‑swappable power modules and fan trays, supporting multiple power redundancy modes (1+1 / 2+2). Supports FE, GE, 10GE SFP+, 25GE SFP28, 40GE QSFP+, 100GE QSFP28 interface boards for flexible port‑density expansion according to business demands. Built‑in native 随‑board AC capability for unified wireless AP management without extra hardware.
• Full‑feature Layer 2 / Layer 3 & carrier‑grade protocol stack: IPv4/IPv6 dual‑stack, static routing, RIP, OSPF, IS‑IS, BGP, VRRP, ECMP, BFD, MPLS and L3VPN functions. Rich Layer‑2 capabilities: 802.1Q VLAN, selective QinQ, STP/RSTP/MSTP, ERPS(G.8032), LACP link aggregation, IGMP Snooping, VBST for multi‑vendor interoperability. Supports complete multicast protocols PIM‑SM/DM/SSM, MSDP for IPTV and massive high‑definition video‑surveillance traffic bearing.
• Multi‑dimensional enhanced security capability: Supports 802.1X / MAC / Portal authentication, DHCP Snooping, ARP anti‑spoofing, ACL filtering, DoS‑attack defense, CPU protection, command‑level authorization and MACsec encryption. Implements strict threat prevention and fine‑grained access control for huge‑scale network environments.
• Powerful hierarchical H‑QoS scheduling: Multi‑dimensional traffic classification based on Layer2‑Layer4 fields; supports SP, WRR, DRR and H‑QoS hierarchical scheduling, traffic policing, shaping and WRED congestion‑avoidance mechanisms, guaranteeing service quality for voice, video and mission‑critical enterprise services. Supports iPCA real‑time network quality detection.
• Carrier‑grade high‑reliability design: 1+1 main‑controller redundancy; service boards, power modules and fan trays support hot‑swap. Supports CSS cluster virtualization, GR/NSF non‑stop forwarding, IP FRR fast protection, IEEE 1588v2 PTP and SyncE time synchronization. Independent environmental monitoring plane with intelligent fan‑speed regulation ensures stable non‑stop operation for core backbone nodes.
• Intelligent diversified O&M: Supports VCMP VLAN centralized management, Zero‑Touch Provisioning, NETCONF/YANG and Telemetry. Multiple management channels: Console CLI, SSH, SNMP v1/v2c/v3, Syslog, FTP/SFTP. Compatible with Huawei iMaster NCE‑Campus for centralized deployment and monitoring of ultra‑large‑scale distributed networks.
