Description: Alcatel OmniSwitch NTP client/server MIB for managing time synchronization servers, keys, and stratum settings.

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 ALCATEL-IND1-NTP-MIB?

ALCATEL-IND1-NTP-MIB is an Alcatel (now Alcatel-Lucent Enterprise) proprietary MIB for the OmniSwitch line, covering configuration and monitoring of the switch's Network Time Protocol (NTP) client and server functions. It exposes data on NTP operating mode (enable/disable, broadcast mode, monitoring), and a peer table listing each configured time-source peer along with its address, type, authentication settings, protocol version, and polling interval. As a monitoring tool it is used to verify that the switch's software clock-synchronization service is healthy, confirming NTP is enabled, that configured peers are reachable and correctly authenticated, and that time sync has not silently failed, which matters because clock drift on a switch can corrupt log timestamps and break certificate/security validation. It is a self-contained enterprise MIB but conceptually parallels the IETF NTP model even though it does not formally import the standard NTPv4 MIB. It is typically deployed on Alcatel-Lucent OmniSwitch campus/data-center switches to keep switch clocks synchronized with upstream time servers. Engineers can download the ALCATEL-IND1-NTP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ALCATEL-IND1-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

  • Alcatel-Lucent OmniSwitch enterprise/campus switches

Monitoring Examples

An administrator would check alaNtpEnable and alaNtpMonitorEnable to confirm NTP service and monitoring are turned on, then walk alaNtpPeerTable/alaNtpPeerEntry to see each configured peer's alaNtpPeerAddress, alaNtpPeerType, and alaNtpPeerAuth settings. A peer entry showing an unreachable alaNtpPeerIpAddress or failing alaNtpPeerAuth would indicate the switch has lost its authenticated time source and may be drifting out of sync. Polling alaNtpPeerMinpoll alongside peer reachability helps confirm the switch is actually completing sync cycles rather than just having NTP configured.

What Can Be Monitored

  • NTP client/server enable status
  • NTP broadcast mode
  • configured NTP peer list
  • peer authentication status
  • peer polling interval
  • NTP monitoring status

How to Use in IPNetwork Monitor

Example using alaNtpStatsStatUptime OID:

Select an Alcatel-Lucent Enterprise OmniSwitch switch 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 alaNtpStatsStatUptime into the Find box to locate it in the OID tree, then select it and click OK. The number of seconds the local NTP server has been associated with the switch. 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 a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the value is unexpectedly low (e.g. under 10 minutes), since that indicates a recent, possibly unplanned, reboot or restart. Click Finish to create the monitor; you can adjust any parameter later.
