Description: Manages Juniper/Unisphere ERX router system configuration, redundancy, and hardware inventory.

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 Unisphere-Data-ERX-System-MIB?

This MIB belongs to Juniper Networks' Unisphere ERX Edge Router Switch product line and covers core system-level management of the chassis and its software. It exposes configuration and inventory data such as chassis hardware revision, software version and build date, and boot and redundancy control settings. It is squarely a hardware/software status MIB: usdERXSysChassisRev and usdERXSysSwVersion/usdERXSysSwBuildDate let an operator confirm exactly what hardware revision and firmware image is running, while the boot-config and auto-revert objects reveal whether a router failed over to a backup configuration after a bad software load. It stands largely on its own as a Unisphere/Juniper enterprise MIB, though it works alongside the standard SNMPv2-MIB (sysUpTime) for uptime tracking. It is typically deployed in service-provider edge networks where ERX routers are polled to track firmware compliance and redundancy events across a large router fleet. Engineers can download the Unisphere-Data-ERX-System-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Unisphere-Data-ERX-System-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/Unisphere ERX Edge Router

Monitoring Examples

An operator would poll usdERXSysSwVersion and usdERXSysSwBuildDate to verify all ERX routers in a fleet are running the expected firmware build after a rollout, and check usdERXSysChassisRev during hardware inventory audits. Watching usdERXSysBootConfigControl and usdERXSysBootAutoRevertControl reveals whether a router automatically reverted to its backup boot configuration -- a sign of a failed configuration change -- and usdERXSysRevertTimeOfDay/usdERXSysBootAutoRevertCountTolerance show when and how many failed attempts triggered that revert. The usdERXSysTrap notification would fire to alert NOC staff in real time when such a boot/revert event occurs.

What Can Be Monitored

  • chassis hardware revision
  • software version and build date
  • boot configuration control state
  • auto-revert count/time tolerance
  • backup configuration usage
  • system traps/notifications
