MIB Viewer — SNMP MIB Browser & Database
MIB Viewer is a free SNMP MIB browser and database with over 19,000 MIBs and 2,500,000 OIDs, covering both the standard, cross-vendor MIBs every device supports and the enterprise-specific MIBs published by individual hardware vendors. Browse the full MIB list, search by name or OID, or use the OID lookup to trace any object's exact position in the tree — view its syntax, access level, and description, and generate a ready-to-run SNMP command, all in your browser, with nothing to install and no account required. The database grows continuously, and beyond the lookup tool itself, the site includes a growing library of written guides and reference material covering SNMP concepts, vendor-specific configuration, DOCSIS cable modem and CMTS monitoring, and troubleshooting — see the Guides menu above, or the highlights below.
Online MIB Browser
MIB Viewer works as a browser for SNMP MIB files the way a code editor browses a file tree: pick a module from the sidebar, or search by name, and the full text of that MIB opens on the right — every object, table, and notification it defines, with syntax, access level, and description rendered in a readable format instead of raw ASN.1. It runs entirely online, in your browser, with nothing to install — just open the site and start browsing.
How MIB files are structured →MIB Database
Behind the browser is a growing database spanning the standard, cross-vendor MIBs every SNMP-capable device implements — IF-MIB, SNMPv2-MIB, HOST-RESOURCES-MIB, and the rest — plus the enterprise-specific MIBs published by hundreds of individual hardware vendors under their own IANA-assigned numbers, organized and searchable by vendor name or enterprise number.
Search MIBs by vendor →OID Search & Lookup
Every value an SNMP agent can report lives at a specific OID — a dotted numeric address like 1.3.6.1.2.1.1.1 — and this OID search resolves that address in either direction: paste a raw OID to look up the object it names, or search by name to find its OID, complete with its exact position in the MIB tree.

MIB Viewer Desktop is a native app for Mac and Windows that brings the same MIB browsing and OID lookup to your desktop, with MIBs and uploaded files saved locally across sessions instead of re-loading them in a browser tab each time. It's built for people who work with the same set of MIBs repeatedly and want them available offline, without a browser window open.
Get MIB Viewer Desktop →MIB File Reader
Have your own MIB file? Drop it on the upload zone in the sidebar (or click to browse) and it's parsed and read right away, with the same navigable view as any MIB already in the database — every object, syntax, and description laid out in full. It's sent to the server to be parsed but isn't added to the shared, publicly searchable database; it stays scoped to your own session.
Upload a MIB file to read →SNMP Translate
The bulk translate tool takes a whole batch of OIDs or object names at once — paste them in or upload a file — and translates every line to the other form in one pass, which is useful for things like resolving the raw OIDs in a captured trap log or an SNMP walk output back to readable names.

What's a MIB?
A MIB (Management Information Base) defines the data a device can report over SNMP — things like interface counters, system uptime, or CPU load — organizing each value under a name and a fixed numeric address. Every MIB module declares a tree of related objects, and a device typically implements dozens of MIBs at once: a handful of universal ones every vendor supports, plus whatever proprietary ones that specific vendor has published.
Read more →What's SNMP?
SNMP (Simple Network Management Protocol) is how routers, switches, servers, and other network devices report status and statistics back to monitoring tools. It's the transport; MIBs are the vocabulary that gives the data it carries any meaning. Most monitoring platforms — Zabbix, PRTG, LibreNMS, Prometheus's SNMP exporter, and plenty of others — rely on this same underlying protocol and MIB structure.
Read more →What's an OID?
An OID is the actual address of one piece of data — a dotted sequence like 1.3.6.1.2.1.1.1, read from the root of a shared global tree down to one specific object. Names are for humans; OIDs are what actually gets sent over the wire. Every vendor's private MIBs live under that vendor's own reserved branch of the same tree, which is what lets one numbering system cover both universal and proprietary data.

What is a MIB browser?
A MIB browser is a tool for reading and navigating MIB files — the definitions that describe what data a device can report over SNMP. Instead of reading raw ASN.1 text by hand, a MIB browser renders each object's name, OID, syntax, and description in a searchable, navigable form. MIB Viewer does this entirely in your browser, for MIBs already in its database or ones you upload yourself.
What is an OID lookup tool?
An OID lookup tool resolves an OID — a dotted numeric address like 1.3.6.1.2.1.1.1 — to the object it identifies, and vice versa: name to OID. MIB Viewer's OID search does both, and shows the object's full definition and its exact position in the MIB tree, not just a bare name.
Is MIB Viewer free to use?
Yes — browsing MIBs, searching OIDs, uploading your own MIB files, and reading the guides are all free, with no account required. MIB Viewer Desktop is a separate paid native app for people who want MIBs saved locally across sessions and offline access, but the web tool itself has no paywall.
Can I look up a MIB from a specific vendor?
Yes — use Search Vendor MIBs under Tools to list every MIB a given vendor has published, searchable by vendor name or IANA enterprise number.
Guides & Resources
Beyond the lookup tool, the site includes practical, hands-on guides and reference material — installing and using the standard SNMP tools, configuring SNMP on specific vendor hardware, monitoring DOCSIS cable modems and CMTSs, and working through the errors people run into most. A few places to start:
SNMP Fundamentals
The manager/agent model, MIBs and OIDs, versions, access control, and all six core operations in one place.
Using net-snmp
Installing the standard Linux SNMP toolkit, the client commands, running an agent, receiving traps, and loading MIBs into each one.
Configuring SNMP on Cisco devices
Community strings, SNMPv3 users, and trap destinations across classic IOS, IOS-XE, and NX-OS — including where NX-OS's syntax genuinely diverges.
Configuring SNMP on Fortinet devices
FortiOS's config system snmp syntax for communities, SNMPv3 users, and choosing which events actually generate a trap.
Understanding MIBs
How objects, tables, and notifications are actually defined, and how vendor-specific numbering keeps everyone's private OIDs from colliding.
Troubleshooting SNMP
From a plain timeout to SNMPv3 auth failures to a MIB that won't parse — working through what actually went wrong and why.
Searching OIDs
Starting from a real device's sysObjectID, searching by name or number, and filtering a MIB down to just the objects you need.
Modem/MTA bootfiles
Compiling modem and MTA configuration files from plain text, and reading real Arris and Hitron examples OID by OID.
DOCSIS Monitoring
Signal quality and status OIDs for both the modem and CMTS side, what changed across DOCSIS versions, and how DOCS-IF3/IF31-MIB extend it for bonded and OFDM channels.
Linux snmpd passthrough
NET-SNMP-EXTEND-MIB and the extend directive in snmpd.conf, used to expose the output of shell scripts as custom OIDs.
Get started
Search for a MIB or OID above, or pick one from the list on the left.
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's sent to the server to be parsed and isn't added to the shared, publicly searchable database — it stays scoped to your own session in the tree on the left.
New here? The Guides menu above is the place to start if you want the concepts explained rather than just looked up.

Bulk Translate
Paste in text that contains SNMP OIDs — snmpwalk output, a log file,
anything — and Translate will find every OID in it and resolve each one to its
full MIB-NAME::objectName.instance name.
Search Vendor MIBs
Search by vendor name (for example juniper) to list every MIB defined under that
vendor’s IANA enterprise numbers. A vendor that holds several enterprise numbers, is
searched under all of them. A number such as 2636 also works.
Search Vendor Traps
Search by vendor name (for example juniper) to list every SNMP notification (trap)
defined under that vendor’s IANA enterprise numbers. Both SNMPv2 NOTIFICATION-TYPE
and SNMPv1 TRAP-TYPE definitions are included. A number such as 2636 also works.
