ERICSSON-ROUTER-PTP-MIB

Description: Manages IEEE 1588 Precision Time Protocol (PTP) clock instances, port states, and timing performance on Ericsson routers.

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.

ERICSSON-ROUTER-PTP-MIB is an Ericsson-specific MIB for managing IEEE 1588 Precision Time Protocol (PTP) on Ericsson router platforms, which use PTP to distribute highly accurate clock synchronization across a packet network (important for mobile backhaul and 5G fronthaul timing). It exposes PTP clock instance configuration, port state, and timing performance data. Its monitoring value is squarely around software/hardware timing status: clock instance state (e.g., master/slave/locked/holdover) and port state reveal whether the router's PTP engine is properly synchronized to its timing source, and timing performance metrics (e.g., offset, path delay) indicate the quality of that synchronization, both critical for detecting timing faults that could disrupt mobile network synchronization. It explicitly builds on the IEEE 1588 PTP standard, layering Ericsson-specific management on top of that protocol model. It's typically deployed on Ericsson routers in mobile operator networks requiring precise timing distribution to base stations. Network engineers evaluating or troubleshooting this functionality can download the ERICSSON-ROUTER-PTP-MIB file directly to load it into their MIB browser.

Because sample_objects for this MIB were not available, specific table/object names cannot be cited, but based on the description an admin would poll PTP clock instance and port state objects to confirm a router's PTP port is in a locked/synchronized state rather than in holdover or faulted state. Tracking timing performance metrics like offset-from-master would reveal degrading synchronization accuracy that could impact downstream mobile base station timing. Without the object list, exact column names for clock/port state cannot be confirmed.
