Huawei CloudEngine CE12812 Modular Core Data‑Center Switch

Product Overview

Key Features

• Ultra‑high‑density modular hardware platform: 27U 19‑inch rack‑mount chassis with 12 LPU service slots, 2 MPU slots, 2 CMU slots, 6 SFU switching fabric slots, 12 power supply slots and 17 fan slots. Supports rich hot‑swappable interface cards of 10GE,25GE,40GE,100GE. Strict front‑to‑back airflow design adapts to standard data‑center cabinet deployment. All critical components support 1+N redundancy and in‑service hot‑swap for non‑stop hardware replacement.
• Full‑feature Layer 2 / Layer 3 and data‑center protocol stack: IPv4/IPv6 dual‑stack, static routing, RIP/OSPF/IS‑IS/BGP, VRRP, ECMP, hardware‑accelerated BFD. Rich Layer‑2 functions: 802.1Q VLAN, selective QinQ, STP/RSTP/MSTP, LACP link aggregation. Supports CSS cluster, VS virtual system, TRILL, VXLAN‑EVPN, SVF vertical virtualization and FCoE converged storage‑computing networking. Comprehensive multicast suite: IGMP Snooping, PIM‑SM/DM/SSM, MSDP, MBGP for IPTV and massive high‑definition video‑surveillance traffic forwarding.
• 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, implementing strict fine‑grained access control and threat mitigation for mission‑critical networks.
• Carrier‑grade advanced QoS: Multi‑field traffic classification based on Layer2‑Layer4 headers; supports SP, WRR, DRR queue scheduling, traffic policing, shaping and WRED congestion‑avoidance mechanisms to guarantee transmission quality for critical services and large‑volume video streams.
• Industrial‑grade high‑availability design: Supports CSS cluster for device‑level redundancy, GR/NSR non‑stop routing, ISSU in‑service software upgrade, multiple link‑level fast‑protection mechanisms to minimize service‑interruption risks. Implements multiple green energy‑saving technologies to reduce overall power consumption.
• Open and intelligent O&M: Supports Zero‑Touch Provisioning, OPS open‑programmable capability, NetStream and sFlow traffic analysis. Management interfaces include Console CLI, SSH, SNMP v1/v2c/v3, Syslog, FTP/SFTP, out‑of‑band Ethernet management port and USB port. Compatible with Huawei iMaster NCE‑Campus for centralized deployment and monitoring of ultra‑large‑scale networks.
