What is ifLastChange?
This read-only object records the system uptime timestamp at the moment when an interface transitioned into its current operational state (up, down, or dormant). It serves as a reference point for how long the interface has remained stable in its current state. Network operators use this to correlate interface state changes with other events and calculate interface stability metrics.
