Abstract

A method for automating replication of network switch configurations within network fabrics, the method includes: obtaining, by a master switch, templates and variables from an administrative system, where a network fabric includes switches and where the master switch is one of the switches assigned a role of master. Additionally, the method includes identifying, by the master switch and in response to the obtaining, a group of switches within the network fabric, authenticating, by the master switch, the group of switches, and generating, by the master switch and based upon the group of authenticated switches, at least one switch profile using the templates and the variables. Further, the method includes applying, by the master switch, the at least one switch profile to the master switch to obtain a configured master switch and applying, by the configured master switch, the at least one switch profile to the group of authenticated switches.
