Configuration groups are reusable blocks of configuration that can be applied multiple times. This makes it similar to a template.
The contents of a configuration group are just normal configuration items. However, it does support regex, so sometimes it may look different.
When a configuration group is applied, it won’t be visible in the normal configuration hierarchy. To see the changes applied by a configuration group, use show configuration | display inheritance.
Good usage of configuration groups includes debugging. You can have your debugging commands ready to go in a group, and only apply them as you need them.
|set groups NAME||Configuration||Create a configuration group|
|set apply-groups NAME||Configuration||Apply a configuration group|
|show | display inheritance||Configuration||See the config that has been inherited from the configuration group|
|wildcard delete||Configuration||Use regex to delete multiple items from configuration|
