    Juniper Networks Enterprise-Specific MIBs

    Juniper Networks enterprise-specific MIBs are supported on QFX3500 and QFX3600 switches, and QFabric systems.

    Note: For information about enterprise-specific SNMP MIB objects, see the SNMP MIB Explorer. You can use SNMP MIB Explorer to view information about various MIBs, MIB objects, and SNMP notifications supported on Juniper Networks devices

    For more information, see:

    • Table 1 for Juniper Networks enterprise-specific MIBs supported on QFX3500 and QFX3600 switches.
    • Table 2 for Juniper Networks enterprise-specific MIBs supported on QFabric systems.

    Table 1: Juniper Networks Enterprise-Specific MIBs Supported on QFX3500 and QFX3600 Switches

    MIB

    Description

    Alarm MIB (mib-jnx-chassis-alarm)

    Provides support for alarms from the switch.

    Analyzer MIB (mib-jnx-analyzer)

    Contains analyzer and remote analyzer data related to port mirroring.

    Chassis MIB (mib-jnx-chassis)

    Provides support for environmental monitoring (power supply state, board voltages, fans, temperatures, and airflow) and inventory support for the chassis, Flexible PIC Concentrators (FPCs), and PICs.

    Chassis Definitions for Router Model MIB (mib-jnx-chas-defines)

    Contains the object identifiers (OIDs) that are used by the Chassis MIB to identify routing and switching platforms and chassis components. The Chassis MIB provides information that changes often, whereas the Chassis Definitions for Router Model MIB provides information that changes less often.

    Class-of-Service MIB (mib-jnx-cos)

    Provides support for monitoring interface output queue statistics per interface and per forwarding class.

    Configuration Management MIB (mib-jnx-cfgmgmt)

    Provides notification for configuration changes and rescue configuration changes in the form of SNMP traps. Each trap contains the time at which the configuration change was committed, the name of the user who made the change, and the method by which the change was made.

    A history of the last 32 configuration changes is kept in jnxCmChgEventTable.

    Ethernet MAC MIB (mib-jnx-mac)

    Monitors media access control (MAC) statistics on Gigabit Ethernet intelligent queuing (IQ) interfaces. It collects MAC statistics; for example, inoctets, inframes, outoctets, and outframes on each source MAC address and virtual LAN (VLAN) ID for each Ethernet port.

    Event MIB (mib-jnx-event)

    Defines a generic trap that can be generated using an operations script or event policy. This MIB provides the ability to specify a system log string and raise a trap if that system log string is found.

    Firewall MIB (mib-jnx-firewall)

    Provides support for monitoring firewall filter counters.

    Host Resources MIB (mib-jnx-hostresources)

    Extends the hrStorageTable object, providing a measure of the usage of each file system on the switch as a percentage. Previously, the objects in the hrStorageTable measured the usage in allocation units—hrStorageUsed and hrStorageAllocationUnits—only. Using the percentage measurement, you can more easily monitor and apply thresholds on usage.

    Interface MIB (Extensions) (mib-jnx-if-extensions)

    Extends the standard ifTable (RFC 2863) with additional statistics and Juniper Networks enterprise-specific chassis information in the ifJnxTable and ifChassisTable tables.

    Ping MIB (mib-jnx-ping)

    Extends the standard Ping MIB control table (RFC 2925). Items in this MIB are created when entries are created in pingCtlTable of the Ping MIB. Each item is indexed exactly as it is in the Ping MIB.

    RMON Events and Alarms MIB (mib-jnx-rmon)

    Supports Junos OS extensions to the standard Remote Monitoring (RMON) Events and Alarms MIB (RFC 2819). The extension augments the alarmTable object with additional information about each alarm. Two additional traps are also defined to indicate when problems are encountered with an alarm.

    Structure of Management Information MIB (mib-jnx-smi)

    Explains how the Juniper Networks enterprise-specific MIBs are structured.

    System Log MIB (mib-jnx-syslog)

    Enables notification of an SNMP trap-based application when an important system log message occurs.

    Utility MIB (mib-jnx-util)

    Provides you with SNMP MIB container objects of the following types: 32-bit counters, 64-bit counters, signed integers, unsigned integers, and octet strings. You can use these objects to store data that can be retrieved using other SNMP operations.

    VLAN MIB (mib-jnx-vlan)

    Contains information about prestandard IEEE 802.10 VLANs and their association with LAN emulation clients.

    Table 2: Juniper Networks Enterprise-Specific MIBs Supported on QFabric Systems

    MIB

    Description

    Analyzer MIB (mib-jnx-analyzer)

    Contains analyzer and remote analyzer data related to port mirroring.

    The QFabric system supports:

    • Analyzer table—jnxAnalyzerName, jnxMirroringRatio, jnxLossPriority.
    • Analyzer input table—jnxAnalyzerInputValue, jnxAnalyzerInputOption, jnxAnalyzerInputType.
    • , Analyzer output table—jnx AnalyzerOutputValue, jnxAnalyzerOutputType.

    Chassis MIB (mib-jnx-chassis)

    Note: The Chassis MIB has been deprecated for the QFabric system. We recommend that you use the Fabric Chassis MIB (mib-jnx-fabric-chassis) for information about the QFabric system.

    Provides support for environmental monitoring (power supply state, board voltages, fans, temperatures, and airflow) and inventory support for the chassis, Flexible PIC Concentrators (FPCs), and PICs.

    Note: On the QFabric system, support for scalar variables (such as memory usage) for the Chassis MIB is limited to the following objects: jnxBoxClass, jnxBoxDescr, and jnxBoxSerialNo.

    Class-of-Service MIB (mib-jnx-cos)

    Provides support for monitoring interface output queue statistics per interface and per forwarding class.

    The QFabric system supports the following tables and objects:

    • Jnxcosifstatflagtable—jnxCosIfstatFlags and jnxCosIfIndex.
    • Jnxcosqstattable—jnxCosQstatTxedPkts, jnxCosQstatTxedPktRate, jnxCosQstatTxedBytes, and jnxCosQstatTxedByteRate.
    • Jnxcosfcidtable—jnxCosFcIdToFcName.
    • Jnxcosfctable—jnxCosFcQueueNr.

    The QFabric system does not support any traps for this MIB.

    Configuration Management MIB (mib-jnx-cfgmgmt)

    Provides notification for configuration changes and rescue configuration changes in the form of SNMP traps. Each trap contains the time at which the configuration change was committed, the name of the user who made the change, and the method by which the change was made.

    A history of the last 32 configuration changes is kept in jnxCmChgEventTable.

    Note: On the QFabric system, these conditions apply:

    • All scalar variables under the jnxCmCfgChg table are supported.
    • Supported scalar OIDs are jnxCmCfgChgLatestIndex, jnxCmCfgChgLatestTime, jnxCmCfgChgLatestDate, jnxCmCfgChgLatestSource, jnxCmCfgChgLatestUser, and jnxCmCfgChgMaxEventEntries.
    • Scalar variables under the jnxCmRescueChg table are not supported.

    Fabric Chassis MIB (mib-jnx-fabric-chassis)

    Provides hardware information about the QFabric system and its component devices. This MIB is based on the Juniper Networks enterprise-specific Chassis MIB but adds another level of indexing that provides information for QFabric system component devices.

    Host Resources MIB (mib-jnx-hostresources)

    Extends the hrStorageTable object, providing a measure of the usage of each file system on the switch as a percentage. Previously, the objects in the hrStorageTable measured the usage in allocation units—hrStorageUsed and hrStorageAllocationUnits—only. Using the percentage measurement, you can more easily monitor and apply thresholds on usage.

    Interface MIB (Extensions) (mib-jnx-if-extensions)
