Description: Juniper Networks MIB for Real-Time Monitor (RTM) providing routing table statistics and forwarding information on Juniper platforms.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is JUNIPER-RTM-MIB?

Despite its short name suggesting a routing-table or generic real-time monitor MIB, the module's actual description and object set show this is Juniper's Real-Time Media (voice/telephony) configuration MIB, covering SIP and analog voice-port templates used on Juniper routers with integrated voice gateway capability. It exposes configuration data for voice services: SIP templates specifying codec selection (G.711 mu-law/A-law, G.729AB), DTMF signaling method, caller ID transmission, class of restriction, and extension inheritance, plus separate analog-line templates. Monitoring emphasis here is primarily configuration/software-state rather than hardware counters — administrators use it to confirm which SIP or analog templates and codec/DTMF settings are applied to voice-enabled interfaces, which indirectly reflects the software status of the router's voice gateway feature set. This MIB works alongside Juniper's voice/telephony (SIP proxy/gateway) feature set rather than a single IETF standard, and complements interface MIBs for the physical voice ports it configures. It is used on Juniper routers with integrated voice interfaces (e.g. branch-office integrated services routers with FXS/FXO ports or SIP trunking) providing branch-office voice services, and administrators often browse its templates with a JUNIPER-RTM-MIB MIB Browser to confirm the correct codec and DTMF settings are applied.

IPNetwork Monitor allows you to monitor SNMP objects defined in JUNIPER-RTM-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • Juniper router with integrated voice/SIP gateway

Monitoring Examples

An administrator would inspect jnxSipTemplateTable/jnxSipTemplateEntry by jnxSipTemplateName to verify which jnxCodecG711MU, jnxCodecG711A, or jnxCodecG729AB codec settings and jnxDtmfMethod are applied to a given SIP trunk template, confirming a misconfigured codec isn't causing call-quality issues. jnxAnalogTemplateTable would be checked similarly for analog (FXS/FXO) port templates, and jnxCallerIdTransmit/jnxClassOfRestriction settings reveal whether caller ID and call-restriction policies are correctly inherited via jnxInheritExtensionsFrom/jnxInheritExtensionsTo. This is largely a configuration-verification MIB rather than a live performance-counter source.

What Can Be Monitored

  • SIP template codec configuration (G.711/G.729)
  • DTMF signaling method
  • caller ID transmission setting
  • analog line template configuration
  • class of restriction / extension inheritance settings
