MIB Smithy

Building/Parsing OBJECT IDENTIFIERs

MIB Smithy SDK provides APIs for creating OIDs for columnar OBJECT-TYPEs from given index values, as well as for parsing index values out of a given instance OID for a columnar object.

Building OBJECT IDENTIFIERs

To create an OID for a columnar OBJECT-TYPE from index values:

Syntax:

% dbcmd buildoid record value ?value ...?

Where:

dbcmd

is the name of the database;

record

is the name or OID of the columnar OBJECT-TYPE; and

value

are the values for each index object (in order). Enumeration labels may be used in place of integer values where applicable. OCTET STRING values may also be specified, and length prefixes are handled automatically depending on whether the corresponding index is declared IMPLICIT.

Returns:

• A single OBJECT IDENTIFIER composed of the OBJECT-TYPE's OID and all instance subidentifiers, including applicable length subidentifers for variable-length indexes.

Parsing OBJECT IDENTIFIERs

Syntax:

To parse an OID for for its index values, either of these forms are equivalent:

• % dbcmd parseoid oid
• % dbcmd get -indexparts oid

Where:

dbcmd

is the name of the database; and

oid

is the OBJECT IDENTIFIER to be parsed.

Returns:

• A list with length that is a multiple of 3, that includes the index name, the subidentifiers for that index, and the raw value parsed from those index subientifiers.
