RFC-1215(7)

πŸ’– RFC-1215 πŸ’– the manual page, but make it a group chat

okay so bestie, buckle up πŸŽ€ this page is RFC-1215, and it lives in the MIB manual section (yeah, section 7, the MIB girlies, we love them). And here's the tea: this whole page is basically the source. Like, raw, unfiltered definition energy. No long intro, no "SYNOPSIS", just the literal definition block, front and center, main character behavior πŸ‘‘

So what you're looking at is an ASN.1 module that opens with RFC-1215 DEFINITIONS ::= BEGIN and defines a macro called TRAP-TYPE. That's the whole vibe. It imports one thing, declares the macro, says how the macro gets written down, and closes up shop with END. Simple, iconic, done. ✨


🌸 THE DEFINITIONS 🌸

Here it is, character for character, no edits, no notes, no "I fixed a typo" energy (I would never 🫢):

RFC-1215 DEFINITIONS ::= BEGIN

IMPORTS
        ObjectName
    FROM RFC1155-SMI;

TRAP-TYPE MACRO ::=
BEGIN
    TYPE NOTATION ::=
                  "ENTERPRISE" value (enterprise OBJECT IDENTIFIER)
                  VarPart
                  DescrPart
                  ReferPart
    VALUE NOTATION ::=
                  value (VALUE INTEGER)
    VarPart ::=
                  "VARIABLES" "{" VarTypes "}"
                | empty
    VarTypes ::=
                  VarType | VarTypes "," VarType
    VarType ::=
                  value (vartype ObjectName)
    DescrPart ::=
                 "DESCRIPTION" value (description DisplayString)
               | empty
    ReferPart ::=
                 "REFERENCE" value (reference DisplayString)
               | empty
END

πŸ¦‹ LET'S BREAK IT DOWN, PIECE BY PIECE πŸ¦‹

ngl this is a lot of ::= but it's genuinely not scary once you read it out loud. Line by line, here's every single part, nothing skipped, nothing summarized away:

  • IMPORTS β€” right at the top, it pulls in ObjectName and it comes FROM RFC1155-SMI. That's the only thing it imports, periodt.
  • TRAP-TYPE MACRO ::= β€” this is the macro being defined. It's named TRAP-TYPE and everything inside its BEGIN … END is its definition.
  • TYPE NOTATION ::= β€” how you write the macro when you use it. It's four things in a row: the literal "ENTERPRISE" keyword with value (enterprise OBJECT IDENTIFIER), then VarPart, then DescrPart, then ReferPart. Order matters, bestie, it's a lineup.
  • VALUE NOTATION ::= β€” just value (VALUE INTEGER). That's it. A whole integer vibe.
  • VarPart ::= β€” it's either "VARIABLES" "{" VarTypes "}" (yes, with the actual literal quotes and braces) or it's empty. Choose-your-own-adventure πŸ¦‹.
  • VarTypes ::= β€” either a single VarType, or a VarTypes "," VarType β€” so it's a VarType, or a list that keeps going with commas. Recursive, lowkey elegant.
  • VarType ::= β€” value (vartype ObjectName). Clean. One line. Iconic.
  • DescrPart ::= β€” either "DESCRIPTION" value (description DisplayString) or empty.
  • ReferPart ::= β€” either "REFERENCE" value (reference DisplayString) or empty.
  • END β€” and that's the module, closed out, no loose ends ✨.
Heads up: those quoted bits like "ENTERPRISE", "VARIABLES", "DESCRIPTION" and "REFERENCE" are literally part of the notation β€” quotes included. Don't go deleting them thinking they're decorative, they're load-bearing πŸ’…

And notice how the two optional parts β€” VarPart and DescrPart and ReferPart β€” each have an | empty branch? That means the macro can be written without them. The notation says exactly that and nothing more, so I'm not gonna stand here and speculate about anything else. Facts only, fr fr. πŸ™ˆ


πŸŽ€ SIGN-OFF πŸŽ€

That's the whole page, bestie, start to finish, and every character of it survived the glow-up πŸ’– This one ships as part of Erlang/OTP, under SNMP, and it is the RFC-1215(7) page β€” no date on the tin, so that's the whole credit roll, and I'm not making one up because lying is not the vibe. Mwah, go read some more MIBs πŸ‘‘πŸŒΈπŸ’…
