You can change the default behavior of the CONFIG or RESET CONFIG button by including the config-button statement at the [edit chassis] hierarchy level:
- config-button <no-rescue> <no-clear>
The no-rescue option prevents the CONFIG or RESET CONFIG button from loading the rescue configuration. The no-clear option prevents the CONFIG or RESET CONFIG button from deleting all configurations on the router.
To return the function of the CONFIG or RESET CONFIG button to its default behavior, do not include the config-button statement in the router configuration.
