What Is HILLSTONE-NTP-MIB?

HILLSTONE-NTP-MIB is a Hillstone Networks proprietary MIB for configuring Network Time Protocol (NTP) server synchronization on Hillstone security appliances (firewalls/UTM devices). It exposes configuration data for one or more NTP server entries that the device uses to keep its system clock accurate. Its monitoring value is software/configuration status — confirming which NTP servers are configured (hillstoneNTPServConfTable) and by extension whether the device's clock source is properly set, which matters because accurate time is essential for correct log timestamps, certificate validation, and correlating security events. It builds directly on the standard NTP protocol though it is Hillstone's own private MIB representation rather than the IETF NTP MIB. It is deployed on Hillstone firewalls and security gateways in enterprise or service-provider networks, where HILLSTONE-NTP-MIB SNMP monitoring helps ensure synchronized time across devices for accurate security event correlation.

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

  • Hillstone Networks firewalls/security gateways

Monitoring Examples

An administrator would poll hillstoneNTPServConfTable to confirm the configured NTP server addresses match the organization's approved time sources. If a configured NTP server entry is missing or unreachable, the firewall's clock could drift, causing log timestamps to become misaligned with other network devices. Regularly checking this table helps ensure time-based security policies and certificate validity checks remain accurate.

What Can Be Monitored

  • configured NTP server addresses
  • NTP synchronization configuration status

How to Use in IPNetwork Monitor

Example using hillstoneNTPServStatus OID:

Select a Hillstone Networks firewall/security gateway (NTP config) 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 hillstoneNTPServStatus into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The status of this NTP server. 1:source(master);2:source(peer);3:selected;4:candidate;5:configured;. 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 an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the value stays at 'candidate' or 'configured' longer than you'd expect, since that means this NTP server hasn't actually been selected as a synchronization source. Click Finish to create the monitor; you can adjust any parameter later.
