    DESCRIPTION
        "Coordinate ifIndex value allocation for entries in usdCbfIfTable.

        A GET of this object returns the next available ifIndex value to be used
        to create an entry in the associated interface table; or zero, if no
        valid ifIndex value is available.  This object also returns a value of
        zero when it is the lexicographic successor of a varbind presented in an
        SNMP GETNEXT or GETBULK request, for which circumstance it is assumed
        that ifIndex allocation is unintended.

        Successive GETs will typically return different values, thus avoiding
        collisions among cooperating management clients seeking to create table
        entries simultaneously.  "
