Hello mffhg,   Referencing the spec sheet, it appears "in hardware" refers to the ASIC ability to support VXLAN functionality and that the hardware will support VXLAN in the N3200 platform on an OS that supports VXLAN. The N3200 series (specifically N3248TE) is able to run OS10, which supports VXLAN OS10 supported hardware list here: [URL] There is no convention for VTEPs on the switch in OS6. OS6 does not support VXLAN.
  Hi all,   in the N3200 speecsheet*, vxlan support is described as the following:  "VXLAN support in hardware only ². ² Can be used if enabled by ON partner network operating system"   What does it mean ("in hardware only")? Is a partner-device with vxlan support according to RFC7348 a ON partner?    We would like to connect VXLAN TEPs between OS10 (S5200 datacenterswitches) and OS6 (N3200 accessswitches) and routers.
