METHOD AND SYSTEM FOR NETWORK DEVICE MAINTENANCE

A method for maintaining a switch. The method includes identifying a first phase to enter in a boot-up process for the switch, where the boot-up process includes a number of phases and the first phase is one of the phases. The method further includes determining a phase exit condition from a first snapshot of the switch, where the first snapshot includes state information for each of the of phases. The method further includes transitioning to the first phase and after transitioning to the first phase: starting a first countdown timer for the first phase, and executing, on the switch, a first networking protocol for the first phase. The method further includes determining, in response to the executing, that a first current state of the switch satisfies the phase exit condition, and exiting the first phase, where the first countdown timer is not expired when exiting the first phase.
