Huawei CloudEngine XH9230‑128DQ High‑Density 400GE AI‑Oriented 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 breakout to 200GE/100GE. Supports iStack stacking and M‑LAG multi‑chassis link aggregation for millisecond‑level link fail‑over and traffic load‑sharing. Configurable front‑to‑back or back‑to‑front airflow adapts to diverse thermal requirements of modern data‑center cabinets. Hot‑swappable power and fan modules support 2+2 redundancy for non‑stop hardware replacement华为企业业....
• 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 capabilities: 802.1Q VLAN, selective QinQ, STP/RSTP/MSTP, LACP link aggregation. Supports VXLAN‑EVPN, SRv6, MoFRR and NSLB enhanced load‑balancing algorithm optimized for AI heavy‑flow scenarios. Comprehensive multicast suite: IGMP Snooping, PIM‑SM/DM/SSM, MSDP for massive video‑streaming traffic forwarding.
• Native iLossless lossless networking for AI workloads: Implements AI‑ECN, PFC deadlock‑avoidance, DPFR fast‑recovery and DPCF congestion‑control technology, effectively reducing packet loss for distributed AI training and storage services, improving overall computing‑cluster efficiency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 AI‑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 training, distributed storage and critical business flows.
• Intelligent telemetry‑driven O&M: Supports Telemetry, IFIT, ERSPAN+ enhanced mirroring, Packet‑Event visibility for real‑time latency, packet‑loss and micro‑burst‑buffer statistics华为企业业.... 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 large‑scale AI‑oriented data‑center networks.
