What is atmFrCnfgLastChange?

This read-only OID records the system uptime value at which the cross-connect last entered its operational state. Engineers use this to correlate connection failures with other network events, diagnosing whether a failure coincided with a device restart or configuration change. A value of 123456789 (in hundredths of a second) means the connection last changed state about 34 days after the device last booted.
