Mismatches occur when a device's actual configuration is different from AirWave's desired config. For each device, there's an Audit page that details what the mismatched settings are.
If the APs' actual configuration is what you want, then you can tell AirWave to want the same thing:
- For 1 AP at a time, go to its Manage page and click Import Settings
- To update many APs, go to a page with a list of them (for example, the APs/Devices tab), click Modify Devices, then check the devices you want to update and click the Import Settings button.
