In both Full Switch and SmartFabric modes, only configuration changes you make using the OME-M UI are retained when you switch modes. The graphical user interface is used for switch configuration in SmartFabric mode and the OS10 CLI is used for switch configuration in Full Switch mode.
By default, a switch is in Full Switch mode. When that switch is added to a fabric, it automatically changes to SmartFabric mode. When you change from Full Switch to SmartFabric mode, all Full Switch CLI configurations are deleted except for the subset of CLI commands that are supported in SmartFabric mode.
To change a switch from SmartFabric to Full Switch mode, you must delete the fabric. At that time, only the configuration changes such as admin password, hostname, and management IP address, will be retained.
The CLI command show switch-operating-mode displays the currently configured operating mode of the switch. This information is also available on the switch landing page in the OME-M UI.
