CloudEngine S1270OE-O8 provides eight LPU slots, four SFU slots, two MPU slots, two CMU slots, and six power module slots1.

The CloudEngine 16800 series switches do not support 4, 8, 12, and 16 LPU slots. According to the CloudEngine 16800 Series Data Center Switches Datasheet, CloudEngine 16800 series switches support three models: CE16804 (4 LPU slots), CE16808 (8 LPU slots), and CE16816 (16 LPU slots). There is no model that supports 12 LPU slots.

BGP EVPN is a control plane protocol that can be used for VXLAN networks . VXLAN is a technology that creates overlay networks to extend Layer 2 connectivity across Layer 3 networks . BGP EVPN has the following functions as a VXLAN control plane protocol:

• It automatically establishes the VXLAN tunnel between VTEPs (VXLAN Tunnel Endpoints), which are devices that encapsulate and decapsulate VXLAN packets . You do not need to manually configure a full-mesh tunnel between all VTEPs, which reduces the configuration complexity and improves the scalability .
• It advertises host routes and MAC address entries on the control plane, which are used to learn the location of hosts and their corresponding VTEPs . This reduces the unknown traffic flooding that occurs when the destination MAC address is unknown, and optimizes the packet forwarding by using optimal paths .
• It implements Layer 2 interconnection between data centers in different networking modes, such as bridging, routing, or integrated routing and bridging (IRB) . This enables seamless communication between hosts in different subnets or VLANs across data centers .
• It advertises subnet routes to implement Layer 3 interconnection of data centers through VXLAN tunnels . This enables routing between different subnets or VLANs across data centers without requiring an external gateway device .

Huawei partners should establish a cyber security assurance system to ensure the cyber security of customers. According to the Huawei Cyber Security Assurance System White Paper, Huawei partners are required to comply with Huawei’s cyber security requirements and standards, implement cyber security management processes and controls, conduct cyber security audits and assessments, and report cyber security incidents.

The CloudEngine 16800 MPUD switch does not have a built-in intelligent processing chip. According to the CloudEngine 16800 Series Data Center Switches Datasheet, CloudEngine 16800 MPUD switch has a built-in management chip that provides management and control functions, but not intelligent processing functions. The intelligent processing chip is embedded in the CloudEngine 16800 AI chip card (AI-NPU), which provides AI-powered network analysis and O&M capabilities.
