This attribute indicates the procedures being used for the Local
Management Interface. This attribute should be ignored if
protocolStatus is not normalCondition. The following procedures
are supported:
none: Local Management Interface procedures are not running on
this interface. This accommodates Frame Relay user equipment that
has not implemented any LMI procedures.
ansi: Local Management Interface procedures from the ANSI
specification are running. DLCI 0 is used for the LMI protocol.
itu: Local Management Interface procedures from the ITU-T
specification are running. DLCI 0 is used for the LMI protocol. Was
previously ccitt.
unknown: Local Management Interface procedures have yet to be
determined by Adaptive LMI.
