Apply All option in Airwave
What is the use of 'Apply All' option in Modify Devices option of Airwave?
Apply All option is introduced in Airwave 8.2.
If you see above screenshots, the number of devices is 1953 and maximum of 500 devices could be seen/selected in a page and other devices could be viewed/selected by navigating to consecutive pages. In order to minimize these navigation 'Apply All' option was introduced.
When option 'Monitor Only + Firmware Upgrades + Apply All' is used, all the devices under group/folders will be changed to monitor mode irrespective of selected/non-selected. It is a good option, however, in case of changes make sure to review what devices are present in the list and if this option is applicable to the situation.
