    DESCRIPTION
        "The MIB module for creation and deletion of Virtual Interfaces
        and Virtual Interface Groups.  In addition to this MIB,
        interface mib (rfc2863) will also contain entries for virtual
        interfaces.

        There are two ways virtual interfaces can be created and bound
        to an interface. The MIB Object cvifGroupsSupported indicates
        if a particular system supports the Virtual Interface Group
        concept.

        If Virtual Interface Groups are supported, then a virtual
        interface is always created/deleted in conjunction with its
        associated Virtual Interface Group. The Virtual Interface
        Group, which may be associated to multiple virtual interfaces,
        is then bound to a physical interface or another virtual
        interface like an EtherChannel.

        If Virtual Interface Groups are not supported, then a virtual
        interface is created/deleted independently. And each virtual
        interface is bound to a physical interface or another virtual
        interface like an EtherChannel.

        In order for a virtual interface to become operational, it must
        be directly or indirectly (via its Virtual Interface Group)
        bound to a physical interface or possibly to another virtual
        interface such as an EtherChannel.

        The cvifGroupTable is only used if the MIB object
        cvifGroupsSupported indicates Virtual Interface Groups are
        supported."
