This stands for Virtual EOS. It is the virtual machine (VM) variant of Arista’s standard switch operating system. : Arista has scheduled the end of software
The key takeaway is that . By using a vEOS VM, you are interacting with the genuine operating system, including its industry-standard CLI, routing protocols (OSPF, BGP, IS-IS, etc.), and advanced features. This consistency is what makes it so valuable; configurations and automation scripts validated on vEOS can be deployed with confidence onto physical Arista switches.
