Something like this extra table, and using the SCSPIDEntryidIndex in
scspDCSTable replacing scspDCSID, and in scspLSTable replacing scspLSID.

    SCSPIDEntryEntry OBJECT-TYPE
        SYNTAX   SCSPIDEntryEntry
        MAX-ACCESS       not-accessible
        STATUS   current
        DESCRIPTION
                "Server ID entry"
        INDEX   {
                 SCSPIDEntryidIndex  
                }
        ::= { SCSPIDEntryTable 1 }

    SCSPIDEntryEntry  ::=
        SEQUENCE {
                SCSPIDEntryidIndex INTEGER,
                SCSPIDEntryid OCTET STRING
                }

    SCSPIDEntryidIndex OBJECT-TYPE
        SYNTAX   INTEGER
        MAX-ACCESS       not-accessible
        STATUS   current
        DESCRIPTION
                "Index into server's table of IDs."
        ::= { SCSPIDEntryEntry 1 }

    SCSPIDEntryid OBJECT-TYPE
        SYNTAX   OCTET STRING    (SIZE (0..255))
        MAX-ACCESS       read-write
        STATUS   current
        DESCRIPTION
                "Server ID"
        ::= { SCSPIDEntryEntry 2 }

Hoylen

P.S. If you are still going to restrict the SCSP specification to fit
the MIB by making the serverID length six bits (a questionable
approach), then the OCTET STRINGs should have a size of 0..63 and not
0..64.
