This MIB module defines MIB objects which provide
mechanisms to manage the parameters used by or
related to Virtual NIC.

Virtual switch extends across one or more
virtualization servers which host the VM instances.
Each virtualization server is represented as a line
card module and is assigned to a unique slot in
the virtual chassis.

All the ports on the virtual switch which can be
hooked up to VM VNICs or to special hypervisor ports
(e.g. vmk or vswif ports) are represented as virtual
ethernet interfaces.

Virtual ethernet interfaces(veths) represent
the switching ports on the virtual switch which
provide networking connectivity to virtual packet
based interfaces such as the Virtual NIC (VNIC)
interfaces defined on a Virtual Machine (VM).

These interfaces are configurable and provide
operational information to the network administrator.

The assignment of virtual ethernet interface ports
to a VM does not change when the VM is migrated.
