MIB - Management Information Base

The database of all viewable/changeable objects in a managed entity. All devices must support the MIB defined in RFC1213 (known as MIB-II) but may include other standards-based MIBs or even custom-designed Enterprise MIBs.

MIBs are written in ASN.1 and are "readable" by normal human beings (well, sort of!). Here is an example MIB entry describing the internal temperature object in the P32mxi:

DESCRIPTION

Object Identifier

The number 1.3.6.1.4.1.3737.2.1.1.1.12 is a unique identifier that represents the internal temperature object (sysInternalTemp) in any P32mxi. Coupled with the IP address of a system, the SNMP Manager can ask for the temperature of any P32mxi in the network.
