Description: Manages time synchronization settings including NTP/SNTP client configuration on D-Link 3100 series 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 DLINK-3100-TIMESYNCHRONIZATION-MIB?

This is a D-Link proprietary MIB module for the D-Link 3100 series managed switches, covering SNTP/NTP-based time synchronization and clock configuration. It exposes configuration data such as the active time-sync method, managed date/time values, time zone settings, and daylight-saving-time rules and offsets. It is primarily a configuration/status MIB used to confirm that a switch's system clock is correctly synchronized; monitoring the reported managed date/time and sync method lets an admin catch clock drift or a failed NTP/SNTP handshake before it corrupts log timestamps or certificate validation. It has an implicit dependency on standard SNTP/NTP protocol behavior even though it is a vendor-private tree rather than referencing IETF MIBs directly. It is typically polled periodically or checked during troubleshooting on D-Link 3100 series switch deployments to validate time-sync health across a fleet, often starting with a DLINK-3100-TIMESYNCHRONIZATION-MIB download to load the module into a MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DLINK-3100-TIMESYNCHRONIZATION-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 3100 series managed switch

Monitoring Examples

An admin can poll rlTimeSyncMethod and rlTimeSyncMethodMode to confirm whether the switch is using SNTP/NTP versus manual time, then cross-check rndTimeSyncManagedDateTime (built from rndTimeSyncManagedTime/rndTimeSyncManagedDate) against a trusted reference clock to detect drift. rlSntpNtpClient and rlSntpNtpConfig reveal whether the SNTP/NTP client is enabled and correctly pointed at a time server. Checking rlDaylightSavingTimeMode, rlDaylightSavingTimeStart/End, and rlDaylightSavingTimeOffset confirms DST rules are applied correctly, which if misconfigured would show up as an hour-off timestamp in logs and traps.

What Can Be Monitored

  • current synchronized date/time
  • time sync method (SNTP/NTP/manual)
  • time zone and offset
  • daylight saving time state
  • SNTP/NTP client enable status
