Management Information Base (MIB)

• Specifies what variables the agents maintain

• Only a limited number of data types are used to define these variables

• MIBs follow a fixed naming and structuring convention called “Structure of Management Information” (SMI). See next slide.

• Variables are identified by “object identifiers”

  • Hierarchical naming scheme (a long string of numbers like 1.3.6.1.2.1.4.3 which is assigned by a standards authority)
  • Eg: iso.org.dod.internet.mgmt.mib.ip.ipInReceives1.3.6.1.2.1.4.3
