Description: Configures and monitors IEEE 1588 Precision Time Protocol on Cisco ME1200 switches.

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 ME1200-PTP-MIB?

ME1200-PTP-MIB is a Cisco private MIB (documented internally as "Private PTP MIB") for configuring and monitoring IEEE 1588 Precision Time Protocol clocks on the Cisco ME 1200 Carrier Ethernet Access Device. It defines configuration tables such as me1200PtpConfigClocksDefaultDsTable (clock type, priority1/priority2, domain number, VLAN tagging, and profile selection among ieee1588/g8265/g8275) and status tables including me1200PtpStatusClocksParentDsTable (grandmaster identity and clock-quality fields), me1200PtpStatusClocksCurrentDsTable, and me1200PtpStatusClocksPortsDsTable (per-port PTP state via ME1200ptpClockPortState values like master/slave/passive/faulty). It also models unicast master/slave negotiation tables and PTP notifications, giving visibility into whether a clock is synchronized, in holdover, or has lost its grandmaster. This is critical for verifying frequency/phase synchronization on mobile backhaul and Carrier Ethernet links where PTP underpins timing-sensitive services. It depends on the switch's underlying clock hardware and VLAN/interface configuration, and is deployed specifically on ME1200 access platforms -- network engineers turn to the ME1200-PTP-MIB MIB Browser view to inspect these clock and port-state objects.

IPNetwork Monitor allows you to monitor SNMP objects defined in ME1200-PTP-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

  • Cisco ME 1200 Carrier Ethernet Access Device

Monitoring Examples

An operator polls me1200PtpStatusClocksPortsDsTable to check that a port's PTP state is master or slave as expected, and reviews me1200PtpStatusClocksParentDsTable for the current grandmaster's clock quality; a port state reporting faulty or a slave clock stuck in holdover (per ME1200ptpSlaveClockState) would indicate a lost or degraded PTP timing reference.

What Can Be Monitored

  • PTP clock configuration (priority, domain, profile)
  • per-port PTP clock port state (master/slave/passive/faulty)
  • parent/grandmaster clock identity and quality
  • slave clock synchronization state (freerun/locking/locked/holdover)
  • unicast master/slave negotiation tables
  • PTP notifications
