MIB OID
Management Information Base (MIB) is the hierarchical database used by the simple network
management protocol (SNMP) to describe the particular device being monitored.
MIB Object IDentifier (OID), as known as a MIB object identifier in the SNMP, is a number assigned
to devices in a network for identification purposes. OID numbering is hierarchical. Using the IETF
notation of digits and dots, resembling very long IP addresses, various registries such as ANSI assign
high-level numbers to vendors and organizations. They, in turn, append digits to the number to
identify individual devices or software processes.
SSH
