Note
•
When you use WPA pre-shared key or WPA2 pre-shared key, the pre-shared key must be statically
set on the phone. These keys must match the keys that are on the AP.
•
When you use Auto (AKM), encryption options are automatically configured for WPA, WPA2,
WPA Pre-shared key, WPA2 Pre-shared key, or CCKM.
•
In AKM mode, the phone authenticates with LEAP if the phone is configured with WPA, WPA2,
or CCKM key management, or if 802.1x is used.
•
The Cisco Unified IP Phone does not support auto EAP negotiation; to use EAP-FAST mode, you
must specify it.
The following table provides a list of authentication and encryption schemes that are configured on the Cisco
Aironet APs that the Cisco Unified IP Phone supports. The table shows the network configuration option for
the phone that corresponds to the AP configuration.
