Description: Manages NTP server configuration, synchronization status, and time source selection on Bay Networks Rapid-City 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 RC-NTP-MIB?

RC-NTP-MIB is a Bay Networks/Nortel enterprise MIB for the Accelar (Rapid-City) switch family that manages Network Time Protocol client configuration and monitors time-synchronization status. It exposes global NTP enable/interval settings and a table of configured NTP servers, including per-server authentication settings and access attempt/success/failure counters. Its main monitoring value is around software/service health rather than physical hardware: it lets an operator verify that the switch's NTP client is actually reaching its configured time servers, spot authentication failures, and confirm the polling interval, all of which affect the accuracy of the switch's system clock used for logging and time-stamped events. It depends on the standard NTP protocol concepts but is an Accelar-specific management layer rather than built on a common IETF NTP MIB. It is deployed on Bay Networks/Nortel Accelar switches wherever accurate device time is needed for syslog correlation, certificate validation, or scheduled operations. Engineers can download the RC-NTP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RC-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.

Monitoring Examples

An operator would enable NTP via rcNtpGlobalEnable and rcNtpGlobalInterval, then poll rcNtpServerTable/rcNtpServerEntry for each configured server's rcNtpServerAddress, rcNtpServerAuthentication, and rcNtpServerKeyId. Rising rcNtpServerAccessFailure counts relative to rcNtpServerAccessSuccess for a given rcNtpServerAddress would indicate that server is unreachable or rejecting authentication, risking clock drift. rcNtpServerRowStatus shows whether a server entry is active, and disabling a failing server via rcNtpServerEnable lets the switch fail over to a healthier time source.

What Can Be Monitored

NTP client enable status and poll interval
configured NTP server addresses
NTP authentication success/failure per server
NTP server access attempt counts
NTP server row/administrative status

How to Use in IPNetwork Monitor

Example using rcNtpServerAccessAttempts OID:

Select a Bay Networks/Nortel Accelar (Rapid-City) switch (NTP client configuration/sync status) 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 rcNtpServerAccessAttempts 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 number of NTP requests sent to this server. 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 counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
