configure system management-interface cli md-cli auto-config-save
configure system management-interface configuration-mode model-driven
3. Log out of the CLI.
4. Log back in to the CLI. The MD-CLI engine is now active.
1.2 Disabling the SR OS MD-CLI
Perform the following procedure to return to classic CLI mode while preserving the current router
configuration.
1. Disable the MD-CLI and model-driven mode in the MD-CLI, using these commands in this order:
configure exclusive
