Small tips 01
For the lab you’ll have to practise, practise and ofcourse practise….
A good way is to start over and over again on every device.
Erase the devices, make sure you got layer 3 connection (If needed) and then save the config to flash or a tftp server (You can use the WCS for this.)
When the WCS is empty, create a backup which you can use to restore the empty config if needed.
When you want to start with a “clean” AP or WLC, just replace the startup with the file saved at the flash and now you can start over and over again..
This saves you time to reconfigure layer 3 over and over again.. (Yes it’s part of the lab, but this should be known already….)
