Description: Manages Precision Time Protocol (PTP) synchronization for Remote PHY nodes in DOCSIS cable networks.

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 DOCS-RPHY-PTP-MIB?

DOCS-RPHY-PTP-MIB is a CableLabs DOCSIS Remote PHY specification MIB that models IEEE 1588 Precision Time Protocol (PTP) clock synchronization status between a CCAP Core and Remote PHY Devices (RPDs) in a distributed cable access network. It exposes PTP clock dataset objects covering default clock properties, current synchronization state, and parent clock relationships. Administrators use it to monitor the software/protocol-level health of time synchronization, including clock quality class, offset from master, mean path delay, and steps removed from the grandmaster, all of which directly affect DOCSIS timing-sensitive services like video and voice. It depends on the broader DOCSIS Remote PHY MIB family and indirectly on IEEE 1588 PTP concepts standardized outside SNMP. It is deployed in cable operator networks using Remote PHY architecture, where CCAP Cores and RPDs must maintain tight clock synchronization over an IP network. Engineers can download the DOCS-RPHY-PTP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DOCS-RPHY-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

DOCSIS Remote PHY Device (RPD)
CCAP Core

Monitoring Examples

An operator would poll docsRphyPtpCurrentDataSetOffsetFromMaster and docsRphyPtpCurrentDataSetMeanPathDelay to verify the RPD's clock remains tightly synchronized to the CCAP Core; a growing offset or path delay would signal a degraded PTP path or network congestion affecting timing accuracy. docsRphyPtpCcapDefaultDataSetQualityClass and docsRphyPtpCcapDefaultDataSetPriority1/Priority2 show the advertised clock quality and priority used in the Best Master Clock algorithm, while docsRphyPtpCcapParentDataSetParentClockId identifies which upstream clock the device is currently locked to, useful for diagnosing unexpected grandmaster failover.

What Can Be Monitored

clock offset from master
mean path delay
clock quality class/accuracy
steps removed from grandmaster
parent clock identity
slave-only/two-step flag configuration

How to Use in IPNetwork Monitor

Example using docsRphyPtpCcapClockStatusPacketsSent OID:

Select a DOCSIS Remote PHY Device/CCAP Core (IEEE 1588 PTP clock sync, vendor-neutral CableLabs standard) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type docsRphyPtpCcapClockStatusPacketsSent into the Find box to locate it in the OID tree, then select it and click OK. This attribute represents the number of PTP packets sent for this clock. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter64-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline (in Packets), since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
