Enterprise specific MIB modules

• Cisco MIBs including lists of MIBs supported in the latest versions of IOS. For the Cisco engineers another server exists.

• Enterasys / Cabletron MIBs

• Juniper MIBs

Companies can register their private MIB modules in the global MIB tree by contacting the Internet Assigned Numbers Authority (IANA). A list of currently assigned enterprise subtrees is maintained by IANA. MIB module specifications are not collected on a central site so you usually have to contact your vendor to get access to the MIB definitions.

MIB modules are defined according to rules defined by the [/ietf/rfcs/rfcbytopic.php#4 Structure of Management Information] (SMI). The SMI is based on the 1988 version of ISO's Abstract Syntax Notation (ASN.1). The ASN.1 Homepage provides further information on ASN.1.
