Advanced networking configuration options allow you greater control over your vSphere networking environment. Enable or Disable IPv6 Support on a Host by Using the vSphere Web ClientThe IPv6 support in vSphere lets hosts work in an IPv6 network that has a very large address space, enhanced multicasting, simplified routing, and so on. Working With Port Mirroring Port mirroring allows you to mirror a distributed port's traffic to other distributed ports or specific physical switch ports. Configure NetFlow Settings with the vSphere Web ClientNetFlow is a network analysis tool that you can use to watch network monitoring and virtual machine traffic. Switch Discovery ProtocolSwitch discovery protocols help vSphere administrators to determine which port of the physical switch is connected to a vSphere standard switch or vSphere distributed switch. Mounting NFS VolumesESXi supports VMkernel-based NFS mounts for storing virtual disks on NFS datastores. Networking Rollback and RecoveryIn vSphere 5.1 and later, you can prevent and recover from network misconfiguration by using rollback, backup configuration files or previous configurations. Configuring Protocol Profiles for Virtual Machine NetworkingA network protocol profile contains a pool of IPv4 and IPv6 addresses that vCenter Server assigns to vApps or to virtual machines with vApp functionality that are connected to port groups associated with the profile. Stateless Network DeploymentStateless is a mode of execution for ESXi hosts with no local storage that formerly would save configuration or state. Configurations are abstracted into a host profile, which is a template that applies to a class of machines. Stateless allows easy replacement, removal, and addition of failed hardware, and improves the ease of scaling a hardware deployment.
