This command specifies whether Wi-Fi Protected Access (WPA) is to use 802.1x
dynamic keys or a pre-shared key.

Command Mode
Interface Configuration (Wireless)
Command Usage
• When the WPA mode is set to "dynamic," clients are authenticated using
802.1x via a RADIUS server. Each client has to be WPA-enabled or support
802.1x client software. A RADIUS server must also be configured and be
available in the wired network.
• In the dynamic mode, keys are generated for each wireless client
associating with the access point. These keys are regenerated periodically,
and also each time the wireless client is re-authenticated.
• When the WPA mode is set to "pre-shared-key," the key must first be
generated and distributed to all wireless clients before they can successfully
associate with the access point.
Example
AP(if-wireless g)#wpa-mode pre-shared-key
