        host).

        Note that for some managed nodes, this object may
        take on only a subset of the values possible.
        Accordingly, it is appropriate for an agent to
        return a `wrongValue' response if a management
        station attempts to change this object to an
        inappropriate value."

     DESCRIPTION
        "The Interface Identifier for this interface that

        is (at least) unique on the link this interface is
        attached to. The Interface Identifier is combined
        with an address prefix to form an interface address.

        By default, the Interface Identifier is autoconfigured

       "The interface's physical address. For example, for
       an IPv6 interface attached to an 802.x link, this
       object normally contains a MAC address. Note that
       in some cases this address may differ from the
       address of the interface's protocol sub-layer.  The
       interface's media-specific MIB must define the bit
       and byte ordering and the format of the value of
       this object. For interfaces which do not have such
       an address (e.g., a serial line), this object should
       contain an octet string of zero length."

    DESCRIPTION
      "The desired state of the interface.  When a managed
      system initializes,  all IPv6 interfaces start with
      ipv6IfAdminStatus in the down(2) state.  As a result
      of either explicit management action or per
      configuration information retained by the managed

      system,  ipv6IfAdminStatus is then changed to
      the up(1) state (or remains in the down(2) state)."

             notPresent(5)      -- missing
            }
    MAX-ACCESS  read-only
    STATUS      current
    DESCRIPTION
      "The current operational state of the interface.
      The noIfIdentifier(3) state indicates that no valid
      Interface Identifier is assigned to the interface.
      This state usually indicates that the link-local
      interface address failed Duplicate Address Detection.
      If ipv6IfAdminStatus is down(2) then ipv6IfOperStatus
      should be down(2).  If ipv6IfAdminStatus is changed
      to up(1) then ipv6IfOperStatus should change to up(1)
      if the interface is ready to transmit and receive
      network traffic; it should remain in the down(2) or
      noIfIdentifier(3) state if and only if there is a
      fault that prevents it from going to the up(1) state;
      it should remain in the notPresent(5) state if
      the interface has missing (typically, lower layer)
      components."

    MAX-ACCESS  read-only

        entered its current operational state.  If the
        current state was entered prior to the last
        re-initialization of the local network management

        subsystem, then this object contains a zero
