What Is TN-DEV-SYS-XNTP-MIB?

TN-DEV-SYS-XNTP-MIB is a Transition Networks enterprise MIB for managing NTP/SNTP time-synchronization client configuration on the device's management system. It exposes configuration objects for the NTP client, including its enabled status, timezone (UTC offset) and daylight saving time rules (start/end period and offset), the device's internal timer, and a table of configured NTP server addresses. Its monitoring role centers on software/configuration status: an operator can confirm tnxNTPClientStatus to see whether time synchronization is active, verify the configured tnxNTPServerTable entries are correct, and check timezone/DST settings to ensure accurate timestamping of logs and traps device-wide, since a time-sync failure can silently corrupt event correlation. It is a self-contained vendor MIB conceptually related to (but not directly dependent on) the IETF SNTP/NTP protocol standards it configures. It is typically deployed on Transition Networks media converters, switches, or NIDs where accurate device time is needed for logging and coordinated troubleshooting. Network engineers evaluating or troubleshooting this functionality can download the TN-DEV-SYS-XNTP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in TN-DEV-SYS-XNTP-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

Transition Networks media converters, switches, and network interface devices

Monitoring Examples

An operator would check tnxNTPClientMgmtTable (tnxNTPClientMgmtEntry) for tnxNTPClientStatus to confirm the NTP client is enabled and running, and walk tnxNTPServerTable (tnxNTPServerEntry) to verify the configured NTP servers match policy. tnxNTPUTCTimezone and the tnxNTPDaylightSavingPeriodStart/tnxNTPDaylightSavingPeriodEnd/tnxNTPDaylightSavingOffset objects would be checked to make sure DST transitions are configured correctly, since an incorrect setting here would make device log timestamps unreliable during troubleshooting.

What Can Be Monitored

NTP client enabled/running status
configured NTP server list
device timezone (UTC offset)
daylight saving time schedule and offset
internal device timer
