Writing and Compiling MIBs

MIB-object-definitions

describe the characteristics of each object in your MIB.

scalar-object-definitions

describe scalar MIB objects. Encode scalar object definitions as described later

in this section, under “Scalar Object Definitions.”

table-definitions

describe tabular MIB objects. Encode table definitions as described later in this

section, under “Table Definitions.”

trap-definitions

describe any traps your subagent generates. Encoding conventions appear later in

this section, under “Trap Definitions.”

You can also embed comments and GDMOC preprocessor directives in your MIB

definition, as the following subsection explains.

GDMOC Comments and Preprocessor Directives

Anywhere within your MIB definition, you can embed comments and GDMOC

preprocessor directives.

Comments

Precede information you want GDMOC to ignore with a double hyphen.

For example:

-- definition of my MIB:

myMibDefinition DEFINITIONS ::= BEGIN--My MIB definition name

...

Preprocessor Directives

You can use the following GDMOC preprocessor directives to control GDMOC

behavior when it compiles your MIB definition. Note, however, that these constructs

may not be recognized by MIB compilers on manager stations, so you need to remove

them before installing your MIB on a manager station.
