Iso Origin - SMC Networks EliteView 6.20 Management Manual

By definition, all single MIB variables have the index 0. Only numbers are used as indices; if other data types are
used as indices, then they are represented by a list of numbers separated by dots (also referred to as dotted-decimal
notation).

iso origin

All objects in the SNMP world begin with the object ISO, which has a unique identifier of 1. In other network
implementations, objects may begin with CCITT (2) or joint-ISO CCITT (3). Each object can be represented by
an object which can uniquely identify itself on the object tree. The notation starts with the root object and each
level represents its descendants.
Example: MIB-2 Identifier
The MIB-2 identifier is known as:
• iso.org.dod.internet.mgmt.mib2, or
• 1.3.6.1.2.1
All common network variables are defined below this object.
Example: A DOS Filename Analogy
For example, MS-DOS uses a hierarchical file naming structure. Initialization information is stored in the EV60
subdirectory. The full path name is:
C:\EV60\NETMGR.INI
which means that the file is:
• Located on drive C
• Directory is EV60
• File name NETMGR.INI
The .INI extension indicates that the file follows the standard Windows convention for program initialization.
By comparison, the EV60.EXE file is an executable file and EV60.HLP is a help file for the EliteView program.
