MIB Viewer

Search, upload, browse, or download from a database of over 11,000 SNMP MIBs. 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

The value of tmnxOamPmCfgSessEthSrcMdIndex specifies the source Ethernet Maintenance Domain (MD) index to be used by the specified session. The source domain can be specified using tmnxOamPmCfgSessEthSrcMdName or tmnxOamPmCfgSessEthSrcMdIndex (not both). tmnxOamPmCfgSessEthSrcMdName is the preferred object for specifying the source domain. One of tmnxOamPmCfgSessEthSrcMdName and tmnxOamPmCfgSessEthSrcMdIndex should be assigned a non-default value. Otherwise, an attempt to start any test belonging to the session will fail. If specified, tmnxOamPmCfgSessEthSrcMdIndex should match a domain created using TIMETRA-IEEE8021-CFM-MIB::tmnxDot1agCfmMdMgmtRowStatus. Otherwise, the session's tests will fail. An attempt to change TIMETRA-SYSTEM-MIB::tmnxSysMgmtIfWriteMode.0 away from 'classic(1)' is blocked if any tmnxOamPmCfgSessEthSrcMdIndex has a non-default value. Zero indicates a value has not been configured.
