Virtual Extensible LAN (VXLAN)

Virtual Extensible LAN (VXLAN) is supported on Dell Networking OS.

Overview

The switch acts as the VXLAN gateway and performs the VXLAN Tunnel End Point (VTEP) functionality. VXLAN is a technology where in

the data trac from the virtualized servers is transparently transported over an existing legacy network.
