Module: Juniper-ERX-System-MIB

OID (symbolic): Juniper-ERX-System-MIB::juniERXSysOperTimingSource

OID (numeric): 1.3.6.1.4.1.4874.2.2.17.1.1.17

Node type: OBJECT-TYPE

Type: JuniTimingSelector

Access: read-only

Description: The operations timing source for the ERX system. The ERX periodically monitors the status of three timing sources, primary, secondary and tertiary. If the systems current timing source fails, the system will automatically downgrade to the next timing source. If the system is configured to automatically upgrade (juniERXSysTimingDisableAutoUpgrade is set to false(2)) the system will switch back to the higher timing source when it becomes available.

What is juniERXSysOperTimingSource?

Reports which of the three timing sources (primary, secondary, tertiary) the system is actually using right now for clock synchronization. If it differs from juniERXSysAdminTimingSource, the configured source has failed and the system has automatically downgraded.
