2635.0. "ASN.1 attributes versus SNMP variables" by ZTOIS1::VISTA (Renato VISTA, SIS Strasbourg, France) Thu Mar 26 1992 11:57

    Hello,
    
    I'm trying to understand the translation rules used to translate ASN.1
    MIB descriptions of attributes to SNMP variables, ie how the SNMP tree
    is calculated from the ASN.1 source file.
    
    Example :
    
    For 	chipGenAddress	from CHIPCOM ASN.1 private MIB source file,
    
    what is the corresponding SNMP tree, ie
    
    		1.3.6.1.4.1.49.?.?.?     ?
    
    Is there any documentations about that subject ?
    
    Thank your for your answers.

2635.1Pretty straightforward ...YAHEY::BOSEThu Mar 26 1992 15:0234
	Renato,
		Here's a simple explanation of how each object gets its
	object identifier. 

		Each object's object id is obtained by appending its sub-id 
	to its parent's object id.

	Example :

	chipcom OBJECT IDENTIFIER ::= { enterprises 49 }
	chipmib01 OBJECT IDENTIFIER ::= { chipcom 1 }
	chipGen OBJECT IDENTIFIER ::= { chipmib01 1 }


	chipGenAddress   OBJECT-TYPE
	SYNTAX  INTEGER
	ACCESS  read-write
	STATUS  mandatory
	DESCRIPTION
	        "An integer that can be used by the Management
 	       Station for whatever purpose it chooses
  	      (e.g., the name of the management station)."
	::=  { chipGen 5 }
 

	We know that the object identifier for enterprises is 1.3.6.1.4.1.
	Thus the object identifier for chipGenAddress is
	1.3.6.1.4.1.49.1.1.5.

	Hope this helps. (You might also want to look at RFC-1065 and RFC-1212
	for further information).

	Rahul.
2635.2SNMP/MIBs : RFC-1065 and RFC-1212 pointers...ZTOIS1::VISTARenato VISTA, SIS Strasbourg, FranceMon Mar 30 1992 08:0810
          
    
    Hello Rahul,
    
    And thank you for your explanations !
    
    Have you got any EASYnet pointers about RFC-1065 and RFC-1212 ? I'm
    very interested by SNMP/MIBs standard descriptions.

	Renato,
		The RFCs can be found on NETRIX in the ~rfc directory.
	From VMS do a  $ dir netrix::"~rfc"  to get a list of all the RFCs.

	Rahul.
