Configuration Groups
Configuration Groups
Configuration groups are reusable blocks of configuration. Its kind of a template you can use to simplify things, like interface configuration.
configure
edit groups
edit Test-Groups
set system services netconf ssh
top
set apply-groups Test-Groups
commit

You cannot see this in the config, since it is inherited. You have to use
show system services | display inheritance
You can create a group containing debug config that you can apply when you need to debug, and unapply groups when you are finished.
You can delete configuration with reged - wildcard delete CONFIG
Example:
edit groups
edit Int-Group
set interfaces <ge-*> description "Unused Interface"
top
set apply-groups Int-Group
commit
