usdERXSysOperTimingSource

Module: Unisphere-Data-ERX-System-MIB

OID (symbolic): Unisphere-Data-ERX-System-MIB::usdERXSysOperTimingSource

OID (numeric): 1.3.6.1.4.1.4874.2.2.17.1.1.17

Node type: OBJECT-TYPE

Type: UsdTimingSelector

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 (usdERXSysTimingDisableAutoUpgrade is set to false(2)) the system will switch back to the higher timing source when it becomes available.

What is usdERXSysOperTimingSource?

Reports which timing source (primary, secondary, or tertiary) is actually in operational use by the ERX system right now. Admins compare this against usdERXSysAdminTimingSource to detect whether the system has failed over from the administratively preferred source.
