MIB Viewer

Search, upload, browse from a database of over 12,000 MIBs and 1,600,000 OIDs. MIB Viewer lets you look up any MIB object by name, OID, or number, 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.

Description

This object allows discovery of how the PDU is wired. It indicates the transferSwitch's first power source which can one of the following: overCurrentProtector transfer switch inlet If the power source is an OverCurrentProtector, it contains the OID of an overCurrentProtectorLabel in the overCurrentProtectorConfiguration Table. The index of the OID can then be used to reference other objects in the overCurrentProtectorConfigurationTable. If the power source is an inlet, it contains the OID of an inletLabel in the inletConfigurationTable. The index of the OID can then be used to reference other objects in the inletConfigurationTable. If the power source is a transferSwitch, it contains the OID of a transferSwitchLabel in the transferSwitchConfiguration Table. The index of the OID can then be used to reference other objects in the transferSwitchConfigurationTable.
