This read-write object controls whether the switch overwrites its local configuration file with the one fetched from the auto-configuration server. Admins enable it when they want centrally managed configuration files to replace whatever is stored locally on the switch, and leave it disabled (the default) to protect local customizations from being overwritten. Setting rcAutoConfigOverwriteEnable to "enable" before a mass config rollout ensures every switch in the field picks up the new server-side configuration rather than keeping its old local settings.
