Spontaneous interference is interference that appears suddenly on a network, perhaps jamming a channel or a range of channels A warning message displays that the AP group will reboot the APs will rejoin the Apply. The CLI enables you to use a VT-100 terminal emulation program to locally or remotely configure, monitor, and control individual controllers and its associated lightweight access points. For coverage holes that can be corrected, the controller mitigates the coverage hole by increasing the transmit power level for that specific access point.
