Huawei CloudEngine S9303E Modular Terabit‑Class Core Routing Switch

Product Overview

Key Features

• Modular scalable hardware architecture: 4U 19‑inch rack‑mount chassis, 3 LPU service slots, dual‑MPU main‑control boards supporting 1+1 master‑backup redundancy. Hot‑swappable power and fan modules, multiple power redundancy modes (1+1). Supports FE, GE, 10GE SFP+, 40GE QSFP+, 100GE QSFP28 interface cards for flexible port‑density expansion based on service demands.
• Full‑feature Layer 2 / Layer 3 protocol stack: IPv4/IPv6 dual‑stack, static routing, RIP, OSPF, IS‑IS, BGP, VRRP, ECMP and BFD. Rich Layer‑2 capabilities: 802.1Q VLAN, selective QinQ, STP/RSTP/MSTP, LACP link aggregation, IGMP Snooping, VBST for multi‑vendor interoperability. Supports comprehensive multicast protocols PIM‑SM/DM/SSM, MSDP for IPTV and large‑scale high‑definition video‑surveillance service bearingHuawei Car....
• Multi‑dimensional enterprise‑carrier‑grade security: Supports 802.1X / MAC / Portal authentication, DHCP Snooping, ARP anti‑spoofing, ACL filtering, DoS‑attack defense, CPU protection, command‑level authorization and MACsec encryption. Realizes 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 to guarantee service quality for voice, video and key enterprise servicesHuawei Car....
• Carrier‑grade high‑reliability design: 1+1 main‑controller redundancy; service boards, power modules and fan trays support hot‑swap. Supports GR/NSF non‑stop forwarding and IP FRR fast protection. CSS cluster virtualization eliminates single‑point‑of‑failure risk and improves overall network reliability. Independent environmental monitoring plane with intelligent fan‑speed regulation ensures stable continuous operation for core‑network nodes.
• Intelligent diversified O&M: Supports CSS cluster, VCMP VLAN centralized management, Zero‑Touch Provisioning, IEEE 1588v2 PTP time synchronization, 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 large‑scale distributed networks.
