Description: Manages D-Link switch NTP client server configuration and synchronization status.
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 MY-NTP-MIB?
MY-NTP-MIB is a D-Link proprietary MIB that manages and reports the Network Time Protocol (NTP) client status on D-Link switches, exposing the switch's view of its time synchronization state. It provides standard NTP status fields, leap indicator, stratum, precision, root delay, root dispersion, reference identifier, and reference timestamp, reflecting how the switch's internal clock is synchronized against upstream time sources. This is a configuration/status MIB used to verify software time-sync health rather than raw hardware metrics: administrators check the stratum and leap-indicator values to confirm the switch has a valid, low-stratum time reference, which matters for accurate log timestamps, certificate validation, and coordinated troubleshooting across a network. It mirrors fields defined by the IETF NTP protocol conventions, applying them to a single switch's NTP client rather than a full NTP server implementation. It is deployed on D-Link managed switches in networks where accurate, synchronized time is required for logging, AAA, and security event correlation. Engineers can download the MY-NTP-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in MY-NTP-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
- D-Link managed switch
Monitoring Examples
An administrator polls myntpSysStratum and myntpSysLeap to confirm the switch is synchronized to a valid NTP stratum (not stratum 16, which indicates unsynchronized) and that no leap-second warning is pending. Reviewing myntpSysRootDelay and myntpSysRootDispersion reveals the accuracy of the time source, while myntpSysRefId and myntpSysRefTime identify which upstream NTP server the switch is currently using and when it last updated. If myntpSysStratum jumps to 16, this signals the switch has lost contact with its NTP server and log timestamps may begin drifting.
What Can Be Monitored
- NTP synchronization stratum
- leap indicator status
- root delay and root dispersion
- reference clock identifier
- reference timestamp
