Huawei CloudEngine CE6881-48S6CQ Data Center Switch – Product Documentation
Product Overview
The Huawei CloudEngine CE6881-48S6CQ is a next-generation, fixed-form-factor 1RU data center switch designed for high-density 10GE server access environments. It serves as an ideal Top-of-Rack (ToR) or aggregation layer solution for modern cloud-oriented data centers and high-end campus networks .
Built on Huawei’s VRP8 software platform, the switch delivers high performance with a switching capacity of 2.16 Tbps and a forwarding rate of 940 Mpps . The CE6881-48S6CQ features 48 x 10GE SFP+ access ports for dense server connectivity and 6 x 100GE QSFP28 uplink ports, each capable of operating as a 40GE QSFP+ port for flexible network design .
The platform supports advanced data center features including VXLAN routing and bridging, BGP-EVPN as the control plane for VXLAN, M-LAG (Multi-Chassis Link Aggregation) for device-level redundancy, and hardware-based congestion management with PFC and ECN for RoCE workloads . It also provides comprehensive programmability through Open APIs, NetConf, and integration with orchestration platforms such as Huawei iMaster NCE-Fabric and Ansible .
The switch is designed with flexible airflow options (front-to-back or back-to-front airflow) and supports hot-swappable redundant power modules and fan trays, ensuring high availability and simplified maintenance .
