Huawei CloudEngine S9312 Modular Terabit‑Class Core Routing Switch

Product Overview

Key Features

• High‑density modular scalable hardware architecture: 15U standard 19‑inch rack‑mount chassis, equipped with 12 LPU service slots, dual MPU main‑control boards for 1+1 master‑backup redundancy. Hot‑swappable power and fan modules, supports multiple power redundancy modes including 1+1 / 2+2, optional PoE power supply. Supports FE, GE, 10GE SFP+, 40GE QSFP+, 100GE QSFP28 interface cards, allowing flexible adjustment of port density according to actual business requirements.
• Complete Layer 2 / Layer 3 protocol stack: IPv4/IPv6 dual‑stack, static routing, RIP, OSPF, IS‑IS, BGP, VRRP, ECMP and BFD. Abundant Layer‑2 functions: 802.1Q VLAN, selective QinQ, STP/RSTP/MSTP, LACP link aggregation, IGMP Snooping, VBST for multi‑vendor interoperability. Supports full‑feature multicast protocols PIM‑SM/DM/SSM, MSDP for IPTV and massive high‑definition video‑surveillance service bearingHuawei Car....
• Carrier‑grade multi‑dimensional security capability: Supports 802.1X / MAC / Portal authentication, DHCP Snooping, ARP anti‑spoofing, ACL filtering, DoS‑attack defense, CPU protection and command‑level authorization. Implements strict threat defense and fine‑grained access management for large‑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 core enterprise services.
• Ultra‑high‑reliability system design: 1+1 main‑controller redundancy; service boards, power modules and fan trays support hot‑swap. Independent environmental monitoring plane, intelligent fan speed regulation, GR/NSF non‑stop forwarding, IP FRR fast protection. Supports CSS cluster virtualization to eliminate single‑point failure and improve overall network reliability.
• Diversified intelligent O&M system: Supports CSS cluster, VCMP VLAN centralized management, Zero‑Touch Provisioning, IEEE 1588v2 PTP time synchronization. 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 large‑scale distributed networks.
