This attribute selects the Local Management Interface (LMI) protocol to
be used on the interface. This attribute is equivalent to the SNMP
variable frDlcmiState. The vendorForum LMI protocol automatically
implies that the DLCI used by the protocol is 1023. The ansi (T1.617
Annex D) and ccitt (Q.933 Annex A) LMI protocols use DLCI 0. If
none is selected, no LMI procedures will run on the interface.
