Description: Manages NTP server synchronization status and stratum information on BlueCat Networks appliances.

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 BCN-NTP-MIB?

BCN-NTP-MIB is a vendor-specific MIB from BlueCat Networks that exposes Network Time Protocol client/server status and statistics on BlueCat DNS/DHCP/IPAM appliances. It reports NTP synchronization state, including leap-second indicator, stratum level, precision, root delay/dispersion, reference identifier and time, poll interval, active peer, and frequency/clock information. Its monitoring focus is clearly on service/software health: confirming the appliance's time is properly synchronized, since a bad stratum, large root delay, or missing reference peer indicates clock drift that can break Kerberos authentication, DNSSEC signing, or log correlation. It is explicitly built on the NTP protocol model documented in RFC 1305 and RFC 5905, referencing University of Delaware NTP research, making it dependent on those standards. It is deployed on BlueCat Networks DNS/DHCP/IPAM appliances in enterprise networks where accurate synchronized time is critical to logging and security operations. Network engineers evaluating or troubleshooting this functionality can download the BCN-NTP-MIB file directly to load it into their MIB browser.

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

BlueCat Networks DNS/DHCP/IPAM appliance

Monitoring Examples

An operator would poll bcnNtpSysStratum and bcnNtpSysLeap to confirm a healthy stratum with no leap-second warning, and check bcnNtpSysRootDelay/bcnNtpSysRootDispersion alongside bcnNtpSysPeer and bcnNtpSerOperState to verify a stable upstream NTP peer. A rising bcnNtpSysStratum, an unset bcnNtpSysPeer, or degraded bcnNtpSerOperState would reveal the appliance has lost its NTP source and its clock is now free-running.

What Can Be Monitored

NTP synchronization state/leap indicator
NTP stratum level
root delay and root dispersion
active NTP peer
NTP service operational state
reference clock/time source

How to Use in IPNetwork Monitor

Example using bcnNtpSerOperState OID:

Select a BlueCat Networks DNS/DHCP/IPAM appliance 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 bcnNtpSerOperState into the Find box to locate it in the OID tree, then select it and click OK. The operational state of this service — running, notRunning (stopped), starting, stopping, or fault. 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 is 'fault', or it stays in 'starting'/'stopping' longer than a normal transition takes. Click Finish to create the monitor; you can adjust any parameter later.
