2. Product Overview (Full English)

The Huawei CloudEngine CE8855-32CQ4BQ is a next-generation, high-performance, high-density 40GE/100GE access switch designed for modern data centers (DCs), providing 200GE uplink ports. As part of Huawei’s CloudEngine 8855 series, this switch is purpose-built for cloud-era data center networks and can also serve as a core or aggregation switch in high-end campus networks.

High-density port configuration – The switch features 32× 40GE/100GE QSFP28 ports and 4× 200GE QSFP56 uplink ports. Each 200GE QSFP56 port can automatically adjust its rate to 40 or 100 Gbit/s. Each 100GE QSFP28 port can be used as one 40GE QSFP+ port or split into four 25GE SFP28 ports or four 10GE SFP+ ports, providing exceptional flexibility in networking.

Key capabilities of the CE8855-32CQ4BQ include:

High switching capacity – Delivers 8 Tbps switching capacity and 2400 Mpps packet forwarding performance
Extensive data center features – Full support for VXLAN routing and bridging, BGP-EVPN as the VXLAN control plane, and M-LAG (Multichassis Link Aggregation Group) for device-level link reliability
Intelligent lossless network – Supports PFC (Priority Flow Control), AI ECN (Explicit Congestion Notification), and DCBX for lossless Ethernet fabric
Comprehensive O&M – Features Telemetry, Netstream, ERSPAN+, and iFIT Packet Event for proactive network health monitoring and troubleshooting
Flexible airflow design – Supports both port-side intake and port-side exhaust with 5 hot-swappable fan modules

The CE8855-32CQ4BQ employs an advanced hardware architecture with a component-based system platform that supports separation of process and kernel, as well as independent maintenance and upgrade of components. The switch can work with CloudEngine 16800, 16800-X, or 8800 DC core switches to build an elastic, virtualized, high-quality, and fully-connected 200GE data center network, meeting the network requirements of data centers in the cloud era. With its high-density 40GE/100GE access and 200GE uplink capabilities, the CE8855-32CQ4BQ helps enterprises and carriers build scalable data center network platforms for the cloud computing era.
