In the headquarters-branch VXLAN interconnection scenario, single-fabric networking is not supported. According to the Huawei CloudCampus Solution Description, headquarters-branch VXLAN interconnection is a scenario that connects multiple campus networks over a WAN using VXLAN tunnels. In this scenario, each campus network forms an independent fabric network with its own controller and gateway devices. Single-fabric networking is a scenario that connects multiple campus networks over a LAN usingVXLAN tunnels. In this scenario, all campus networks share the same fabric network with a unified controller and gateway devices.

Huawei AirEngine 6760 series supports four spatial streams by default, but after an RTU (Right To Use) license is purchased, it can support up to eight spatial streams on the 5 GHz band. It can also support four spatial streams on the 2.4 GHz band or scanning mode. Therefore, the possible spatial stream combinations are 4+8, 4+8+4, 4+4+scanning, and 4+6+scanning.
