Huawei CloudEngine CE6875-48S4CQ-EI Product Documentation
Product Overview
The Huawei CloudEngine CE6875-48S4CQ-EI is a next-generation, high-performance Top-of-Rack (ToR) data center switch designed for cloud computing environments and high-end campus networks . As a 1U form-factor switch, it provides a high-density 10GE access layer solution with advanced 40/100GE uplink capabilities .

At the core of its design is a 4 GB ultra-large packet buffer, which is dynamically shared among all ports. This capacity, which is significantly higher than industry average, enables the switch to effectively handle traffic bursts common in video streaming, search, and other data-intensive services . The switch is powered by the Huawei VRP8 software platform, delivering extensive data center features, high stacking capabilities, and programmability .

The CE6875-48S4CQ-EI supports advanced network virtualization technologies, including VXLAN routing and bridging with BGP-EVPN control plane, which enables the construction of large-scale, multi-tenant overlay networks . It supports M-LAG (Multi-Chassis Link Aggregation) for device-level redundancy and active-active forwarding, ensuring high availability and simplified operations . Furthermore, this model specifically supports MACsec hardware-based encryption, providing hop-by-hop data confidentiality and integrity for security-sensitive deployments .

The switch offers flexible airflow designs (front-to-back or back-to-front) and supports redundant, hot-swappable power supplies and fan modules, making it suitable for various data center environmental requirements . With its combination of high-density ports, large buffer, and virtualization features, the CE6875-48S4CQ-EI is ideal for use as a top-of-rack switch in large data centers or as an aggregation/core switch in enterprise campus networks .
