Abstract
Synchronization of configuration files of a virtual application distribution chassis, includes: processing a configuration command received by a master blade; updating a first configuration file with the configuration command and an updated tag by the master blade; sending a configuration message by the master blade to the slave blades informing of the updated configuration file, the configuration message comprising the updated tag; in response to receiving the configuration message by a given slave blade of the one or more slave blades, comparing the updated tag in the configuration message with a tag in a second configuration file stored at the given slave blade; and in response to determining that the updated tag in the configuration message is more recent than the tag in the second configuration file stored at the given slave blade, sending a request for the updated configuration file to the master blade by the given slave blade.
