Spine nodes are core nodes on the fabric network, but they do need to support VXLAN in some scenarios. According to the Data Center Networking: What It Is, Why It Matters, And Types article, VXLAN is a tunnel encapsulation technology that allows overlay networks to be created on top of the underlay network. Spine nodes need to support VXLAN when they act as gateways between different overlay networks or between overlay and underlay networks.

 CloudEngine S7700 switches support service port clustering and CSS2 switch fabric clustering. According to the CloudEngine S7700 Series Switches Datasheet, service port clustering enables multiple physical ports to form a logical port that provides higher bandwidth and link redundancy, while CSS2 switch fabric clustering enables multiple switches to form a logical switch that provides higher performance and simplified management.

CloudEngine S12700E does not support PoE. PoE is a technology that allows network devices to receive power from data cables instead of power cables. PoE is usually used for access switches that connect to devices such as IP phones and wireless APs, but not for core switches such as CloudEngine S12700E. A single CloudEngine S12700E can manage up to 10K APs by integrating native WLAN AC capabilities4. A single CloudEngine S12700E can manage up to 50K terminals by using free mobility feature that ensuresconsistent user experience across wired and wireless networks4. CloudEngine S12700E integrates hardware-based OAM/BFD to provide fast fault detection and location for various services such as Ethernet, IP, MPLS, and VxLAN

Free mobility is supported on a hybrid network consisting of Huawei and third-party devices, and the authentication point can be deployed on third-party devices. According to the Huawei CloudCampus Solution Description, free mobility is a feature that allows users to access network resources without changing their IP addresses or VLANs when they move within a virtual network (VN). Free mobility can be implemented on a hybrid network by using VXLAN tunneling technology and policy association.
