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 tmnxOamPmCfgSessIpDscpName specifies the Differentiated Services Code Point (DSCP) to be copied into the IP header of each echo request packet launched for each test belonging to the specified session. The specified DSCP name must match a TIMETRA-QOS-MIB::tDSCPName defined in TIMETRA-QOS-MIB::tDSCPNameTable. The mapping between the specified DSCP name (e.g. 'af43') and the numeric value needed in the IP header (e.g. 38) is provided by TIMETRA-QOS-MIB::tDSCPNameDscpValue. If the value of this object is the empty string, the DSCP copied into the IP header is derived by SROS from the specified session's forwarding class and profile (i.e. tmnxOamPmCfgSessIpForwardClass and tmnxOamPmCfgSessIpProfile), using TIMETRA-QOS-MIB::tNetworkEgressFCDSCPInProfile and TIMETRA-QOS-MIB::tNetworkEgressFCDSCPOutProfile for network Quality of Service (QoS) policy 1. The interaction with tmnxOamPmCfgSessIpDscpEgrRemark is explained in the tmnxOamPmCfgSessIpDscpEgrRemark DESCRIPTION clause.
