How unique must MIB variable names be?
1) OIDs are unique identifiers for all-space-and-time. An OID value is an ordered sequence of nonnegative integers that contains at least two members with the value of the first member restricted to 0, 1, or 2, and the value of the second member restricted to 0 to 39 if the value of the first is 0 or 1. SNMP calls members of the sequence sub-identifiers. SNMP restricts an OID value to have at most 128 members, and no member can have a value greater than 4G-1 (4294967295). 2) For convenience of people, a label can be associated with each member of a sequence. Additionally, there are “well known” labels for OID values. SNMP reccognizes only “ccitt”, “iso”, and “joint-iso-ccitt” as well known labels for the first member in a sequence. 3) There can be multiple labels associated with an OID value! (Few SNMP utilities can cope with this.) 4) OID values in SNMP messages are sequences of integers. A sequence of labels is never used. 5) Most items defined in SNMP MIB modules are identified by a
