Patent ID: 7003692

Claim:
A method for maintaining processor synchronization in a system having an Active processor that controls all system resources that are providing service and a Standby processor for assuming control if the Active processor fails or a manual request is made to switchover, with each processor including memory for storing a startup-config file, the method comprising: bulk synchronizing the Standby and Active processors at a first point of synchronization by: copying a startup configuration file from the Active processor to the Standby processor; creating a file system on the Standby processor memory for running configuration synchronization; sending a running configuration file from the Active processor to the Standby processor and generating the running configuration at the Standby processor which is stored in the file system; and dynamically synchronizing the Standby and Active processors subsequent to the first point of synchronization by: synchronizing subsequent configuration changes on the Active processor to the Standby processor thereby maintaining configuration synchronization between the processors.
