Few third party devices have managment support aswell in Airwave. In Aruba case, if we have activate subscritpion we could do zero touch provision but in case of third party vendor. plug and play does not work, either you have to add the devices manually or CSV or using discovery method.
Default device will be discovered in new device list in Airwave, since you want to push the configuration automatically, we could enable automatic authorization in airwave and set proper folder/group where we have global configuration template.
Once switch get discovered automatically swtich move to respective group/folder and the configuration will get pushed.
Note: We need to make sure device will added in manage mode only so that conifguration will get pushed.
In AMP Setup > General page, we have automatic authoriziation section where we need to enable below settings
