METHOD AND SYSTEM FOR NETWORK DEVICE MAINTENANCE

摘要

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.

1. A non-transitory computer readable medium comprising instructions, which when executed by at least one processor perform a method, the method comprising:
identifying a first phase to enter in a boot-up process for a switch, wherein the boot-up process comprises a plurality of phases and the first phase is one of the plurality of phases; determining a phase exit condition from a first snapshot of the switch, wherein the first snapshot comprises state information for each of the plurality of phases; transitioning to the first phase; after transitioning to the first phase:
starting a first countdown timer for the first phase;executing, on the switch, a first networking protocol for the first phase;determining, in response to the executing, that a first current state of the switch satisfies the phase exit condition; andexiting the first phase, wherein the first countdown timer is not expired when exiting the first phase.
