I have validated that our WLC has the key hash for the mac address of our CMX.   but i can't get them to provide any credentials for adding the controller, either through snmp community write string or importing from PI (root credentials).   it seems...

If i want to import a controller into CMX, what command would i have to do on the WLC to export the controller FILE? can't seem to find that reference.

what command can be used to add the controller if the keys are already set up on the WLC? when i try to add the controller it still asks me for a write community string and it still fails if i dont put anything in that query
