Using the CLI to Configure WPA1+WPA2
Follow these steps to configure a WLAN for WPA1+WPA2 using the controller CLI.
Step 1 Enter this command to disable the WLAN:
config wlan disable wlan_id
Step 2 Enter this command to enable or disable WPA for the WLAN:
config wlan security wpa {enable | disable} wlan_id
Step 3 Enter this command to enable or disable WPA1 for the WLAN:
config wlan security wpa wpa1 {enable | disable} wlan_id
Step 4 Enter this command to enable or disable WPA2 for the WLAN:
config wlan security wpa wpa2 {enable | disable} wlan_id
Step 5 Enter these commands to enable or disable AES or TKIP data encryption for WPA1 or WPA2:
• config wlan security wpa wpa1 ciphers {aes | tkip} {enable | disable} wlan_id
• config wlan security wpa wpa2 ciphers {aes | tkip} {enable | disable} wlan_id
The default values are TKIP for WPA1 and AES for WPA2.
Step 6 Enter this command to enable or disable 802.1X, PSK, or CCKM authenticated key management:
config wlan security wpa akm {802.1X | psk | cckm} {enable | disable} wlan_id
The default value is 802.1X.
Step 7 If you enabled PSK in Step 6, enter this command to specify a pre-shared key:
config wlan security wpa akm psk set-key {ascii | hex} psk-key wlan_id
WPA pre-shared keys must contain 8 to 63 ASCII text characters or 64 hexadecimal characters.
Step 8 If you enabled WPA2 with 802.1X authenticated key management or WPA1 or WPA2 with CCKM
authenticated key management, the PMK cache lifetime timer is used to trigger reauthentication with the
client when necessary. The timer is based on the timeout value received from the AAA server or the
WLAN session timeout setting. To see the amount of time remaining before the timer expires, enter this
command:
show pmk-cache all
Information similar to the following appears:
