its configuration file and backups the configuration file to the slave module
simultaneously when the master’s configuration file is modified, so as to ensure
the consistency of the configurations of the master system and slave system.
You can enable/disable automatic synchronize of the Switch 7758.

This operation can backup the configuration file to the slave module only if the
slave system operates normally. The configuration file will be fully copied at each
time the operation is executed.
