Description: Configures NTP/SNTP time synchronization servers and settings on Cisco Small Business 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 CISCOSB-TIMESYNCHRONIZATION-MIB?

CISCOSB-TIMESYNCHRONIZATION-MIB is a Cisco Small Business private MIB that configures the device's time synchronization via SNTP/NTP, along with time zone and daylight-saving-time rules. It exposes the device's currently managed time and date, the synchronization method in use, time-zone code, and daylight-saving start/end/offset settings. Its monitoring value is software/configuration status rather than hardware health: administrators use it to verify the device's clock is correctly synchronized and that time zone/DST rules are properly applied, since incorrect time can undermine log timestamps, certificate validation, and scheduled jobs across the network. It functions alongside standard NTP but is implemented as a CISCOSB private-tree client configuration MIB rather than the IETF NTP MIB. It is deployed on small-business switches/routers to keep device clocks consistent with a central time source. Engineers can download the CISCOSB-TIMESYNCHRONIZATION-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCOSB-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

  • Cisco Small Business switches and routers

Monitoring Examples

An administrator would poll rndTimeSyncManagedDateTime and rlTimeSyncMethod to confirm the device is synchronized via NTP/SNTP rather than running on free-running local time, then check rlSntpNtpClient and rlSntpNtpConfig to verify the configured time server is reachable. Reviewing rlDaylightSavingTimeMode, rlDaylightSavingTimeStart, and rlDaylightSavingTimeEnd confirms DST transitions are configured correctly for the local region. A device whose rndTimeSyncManagedDateTime drifts significantly from the network's reference time usually points to a failed or misconfigured rlSntpNtpConfig entry.

What Can Be Monitored

  • current managed date/time
  • time synchronization method
  • NTP/SNTP server configuration
  • time zone code
  • daylight saving time schedule and offset
