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.
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
Supported Devices
- Bay Networks/Nortel Accelar (Rapid-City) switches
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.
