Huawei CloudEngine CE7855‑32Q‑EI High‑Density 40GE Fixed Data‑Center Switch

The Huawei CloudEngine CE7855‑32Q‑EI is a 1‑rack‑unit high‑performance short‑depth fixed‑port Layer2‑Layer3 switch within CloudEngine 7800 series, running on Huawei VRP‑8 operating system. It is equipped with 32×40GE QSFP+ ports; each QSFP+ port supports 1‑to‑4 breakout into four 10GE SFP+ ports for flexible port resource adjustment. Optimized for Spine‑Leaf fabric architecture in cloud data‑centers, it can serve as spine node, high‑end aggregation or leaf switch. It is also suitable for aggregation or core‑layer deployment for large‑enterprise campus and mega‑scale safe‑city video‑surveillance networks. It supports iStack stacking, M‑LAG, TRILL, VXLAN‑EVPN, SVF vertical virtualization and FCoE converged storage‑computing networking. Hot‑swappable power and fan modules are sold separately.

Short‑depth high‑density 40GE hardware platform: 1U 19‑inch short‑depth rack‑mount chassis, 32 wire‑speed 40GE QSFP+ ports with 1‑to‑4 10GE breakout capability. iStack stacking supports up to 16 members, M‑LAG delivers millisecond‑level link fail‑over. Configurable front‑to‑back or back‑to‑front airflow adapts to various cabinet depth‑limited deployment scenarios. Hot‑swappable power and fan modules support 1+1 redundancy.
Full‑feature Layer 2 / Layer 3 and data‑center protocol stack: IPv4/IPv6 dual‑stack, static routing, RIP, OSPF, IS‑IS, BGP, VRRP, ECMP and hardware‑accelerated BFD. Rich Layer‑2 capabilities: 802.1Q VLAN, selective QinQ, STP/RSTP/MSTP, LACP link aggregation. Supports TRILL, VXLAN‑EVPN, SVF vertical virtualization and FCoE storage convergence. Comprehensive multicast suite: IGMP Snooping, PIM‑SM/DM, MSDP 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 fine‑grained access control and threat mitigation for data‑center and large‑scale enterprise environments.
Advanced high‑performance 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.
Carrier‑grade high‑availability design: Hot‑swappable power and fan modules; supports stack redundancy, M‑LAG and link‑level fast‑protection mechanisms to reduce service‑interruption risks.
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 large‑scale networks.

Application Scenarios

Primarily deployed as high‑density 40GE spine or leaf node inside cloud‑computing data‑center Spine‑Leaf fabric, interconnecting leaf switches and high‑performance servers via 40GE interfaces. The short‑depth chassis fits cabinets with limited installation depth. With native FCoE capability, it supports converged storage‑computing network deployment. Also applicable as high‑end aggregation‑layer or small‑size core‑layer device for large‑enterprise campus networks and mega‑scale safe‑city video‑surveillance networks. Cooperates with high‑end core switches such as CloudEngine 12800 series to build elastic virtualized data‑center fabric networks.
