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.
This object is obsolete. IPv6 does not have a
separate operational status; the operational status of the
interface is represented by IF-MIB::ifOperStatus.
