Description: The value of sysUpTime when the jnxMacChangedNotification containing the information denoted by the jnxHistMacChangedMsg object in this entry was generated.
What is jnxHistTimestamp?
This is the value of sysUpTime recorded when the MAC-change notification tied to this history-table entry was generated. Admins use it to determine when a specific MAC learn, remove, or update event occurred relative to device uptime, which is essential for correlating MAC changes with other timestamped events during troubleshooting. Comparing jnxHistTimestamp values across entries lets an admin see that a burst of MAC changes all occurred within the same few seconds, suggesting a link flap rather than independent events.
