Huawei CloudEngine CE9866‑128DQ High‑Density 400GE AI‑Optimized Data‑Center Switch

Product Overview

Key Features

• Ultra‑high‑density 400GE hardware platform: 4U 19‑inch rack‑mount chassis with 128 wire‑speed 400GE QSFP112 ports and 2×10GE SFP+ auxiliary ports. 400GE interfaces support 1‑to‑4 breakout to 100GE. Supports iStack stacking and M‑LAG for device‑level virtualization and millisecond‑level link fail‑over. Optional front‑to‑back or back‑to‑front airflow satisfies diverse data‑center cabinet thermal requirements. Hot‑swappable power and fan modules support 1+N redundancy for non‑stop hardware replacement.
• Full‑feature Layer 2 / Layer 3 and advanced data‑center protocol stack: IPv4/IPv6 dual‑stack, static routing, OSPF, IS‑IS, BGP, VRRP, ECMP, hardware‑accelerated BFD with minimum 3.3‑ms detection interval. Rich Layer‑2 functions: 802.1Q VLAN, selective QinQ, STP/RSTP/MSTP, LACP link aggregation. Supports VXLAN‑EVPN, SRv6, NSLB enhanced load‑balancing algorithm optimized for AI large‑flow scenarios. Comprehensive multicast suite: IGMP Snooping, PIM‑SM/DM/SSM, MSDP for massive video and streaming‑service traffic forwarding.
• Intelligent lossless network capability: Native iLossless AI‑oriented congestion‑control algorithm, supporting AI‑ECN, PFC deadlock prevention, DPFR fast‑restart technology, effectively reducing packet loss for AI training and distributed storage services华为企业业....
• Multi‑dimensional security protection: Supports 802.1X, MAC‑based authentication, DHCP Snooping, ARP anti‑spoofing, ACL filtering, DoS‑attack defense, IP source guard, port security and broadcast/multicast/unknown‑unicast storm suppression, delivering fine‑grained access control and threat mitigation for mission‑critical computing networks.
• Advanced high‑performance QoS: Multi‑field traffic classification based on Layer2‑Layer4 headers; supports PQ, DRR, PQ+DRR queue scheduling, traffic policing, shaping and WRED congestion‑avoidance mechanisms to guarantee transmission quality for AI, storage and critical business flows.
• Intelligent telemetry‑enabled O&M: Supports Telemetry, IFIT, ERSPAN enhanced traffic mirroring, Packet‑Event visibility for real‑time packet‑loss and latency monitoring, micro‑burst buffer statistics. Management interfaces include Console CLI, SSH, SNMP v1/v2c/v3, Syslog, FTP/SFTP and USB port. Compatible with Huawei iMaster NCE‑Fabric for centralized deployment and monitoring of AI‑oriented large‑scale data‑center networks华为企业业....
