Description: 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.
