Hi neilb376,
if you manage your switches through central, then there is no way to add another different management system like AirWave. But you can always manage those switches through CLI.
As long as the switch is connected to Central, the config from Central will override local changes. So you should make sure that your primary change process will be through central.
In the case of a disconnect from Central, you can manage those switches through CLI and do all the changes needed. But you should make sure, that you also do the changes in Central because whatever happened, the switch will somehow reconnect to central and get a new update from there. And it might happen, that your changes are then overridden.
