An OBJECT IDENTIFIER value is an ordered list of non-negative numbers. For the SNMPv2 framework, each number in the list is referred to as a sub-identifier, there are at most 128 sub- identifiers in a value, and each sub-identifier has a maximum value of 2^32-1 (4294967295 decimal). All OBJECT IDENTIFIER values have at least two sub-identifiers, where the value of the first sub- identifier is one of the following well-known names:
