MBG-SNMP-XPT-MIB

Description: Meinberg Radio Clocks XPT (Expandable PTP/NTP) device MIB providing precision time protocol and frequency management objects.

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.

MBG-SNMP-XPT-MIB is a Meinberg enterprise MIB for the XPT family of precision timing devices, covering GPS-based reference clocks used to discipline NTP/PTP time servers. It exposes reference-clock configuration and status objects for up to multiple GPS reference inputs, including receiver type/mode, GPS lock state, antenna/position data, and satellite counts (in view versus actually used/'good'). Its monitoring value is centered on the hardware status of the timing subsystem: whether the GPS receiver has a valid position fix, how many satellites it is tracking, and whether the reference clock is in a healthy locked state, all of which determine the trustworthiness of the time the device distributes. As a timing appliance MIB it sits at the top of Meinberg's SNMP enterprise tree and is typically used alongside other Meinberg system/NTP MIBs for full device status, though this module focuses specifically on GPS reference and SCU (System Clock Unit) objects. It is deployed on Meinberg time servers/clocks in data centers, broadcast facilities, or telecom sites requiring precise, GPS-disciplined timing. Engineers can download the MBG-SNMP-XPT-MIB file directly to load it into their MIB browser.

An admin would check mbgGPSRef1GpsStateVal to confirm the GPS receiver is in a locked/valid state, and mbgGPSRef1GpsSatellitesGood versus mbgGPSRef1GpsSatellitesInView to see how many visible satellites are actually being used for the fix -- a low 'good' count despite many in view could indicate antenna or signal-quality problems. mbgGPSRefclock1Mode and mbgGPSRefclock1Type confirm the receiver's configured operating mode matches the installed hardware. A degraded or unlocked GPS state here would explain drifting or unreliable NTP/PTP time distributed by the appliance.

Meinberg global time management MIB for SNMP transport (XPT); manages GPS/atomic clock time servers and synchronization devices.
