MIB Viewer

MIB Viewer is a free SNMP MIB browser and database with over 12,000 MIBs and 1,600,000 OIDs. Search by name, OID, or number to look up any MIB object, view its syntax, access level, and description, trace its place in the MIB tree, and generate ready-to-run SNMP commands — all in your browser.

What's a MIB?

A MIB (Management Information Base) is a structured document that defines the data a device exposes over SNMP — things like interface counters, system uptime, or CPU load. Each module declares a set of named objects, organized into a tree.

What's SNMP?

SNMP (Simple Network Management Protocol) is how network devices — routers, switches, servers — report status and statistics to monitoring tools. It's the protocol; MIBs are the vocabulary it uses to describe what's being asked for.

What's an OID?

An OID (Object Identifier) is the numeric address of one piece of data in a MIB — a dotted sequence like 1.3.6.1.2.1.1.1, read from the root of a global tree down to one specific object. Names are easier to read; OIDs are what's actually sent over the wire.

Have your own MIB file? Drop it on the upload zone in the sidebar (or click to browse) to parse and explore it right away — it stays private to this browser session and isn't added to the shared library.
