mib2c - show all variable attributes

Question

I am very new to mib2c, and I need to list all attributes which belong to one variable. I work with mib2c tool from NET-SNMP and there are configuration templates for generating the code.

There are variables with many attributes, look like:

$var.defval
$var.type

I would like to see all these attributes, in order to use them in the generated code. I know, for mib2c attributes there is man page, but there is not everything. (For example I know the attribute $var.needlength exists, and it is not mentioned in that man page).

I don't know how the $var is defined and fulfilled.

How can I list all attributes of $var?

Answer 1

I'm not sure how you can do this programmatically, given the constraints of the mib2c pseudo-Perl but I just looked in /usr/bin/mib2c (it's a script, not a compiled executable so you can easily examine the code) and found the following.

There are only four undocumented variables in the mib2c script:

• lastchange
• storagetype
• needlength
• enumrange

There are many more documented variables in the mib2c script:

• uc
• objectID
• commaoid
• oidlength
• subid
• module
• parent
• isscalar
• iscolumn
• children
• perltype
• type
• decl
• readable
• settable
• creatable
• noaccess
• accessible
• rowstatus
• hasdefval
• defval
• hashint
• hint
• ranges
• enums
• access
• status
• syntax
• reference
• description

That being said, I'm not sure what exactly you are hoping to find, so I'm not sure that this really answers your question.
