This object is used to provision the default administrative
OAM mode for this interface. This object represents the
desired state of OAM for this interface.
The hh3cDot3OamAdminState always starts in the disabled(1) state
until an explicity management action or configuration
information retained by the system causes a transition to the
enabled(2) state.
Note that the value of this object is ignored when the
interface is not operating in full-duplex mode. OAM is not
supported on half-duplex links.
