WM-AD configuration
4 Select WPA-PSK.
5 Select WPA v1.
If you select WPA v1, its subordinate Encryption drop-down menu is enabled.
The Encryption drop-down menu offers you the following two options:
Auto – If you click Auto, the Wireless AP advertises both TKIP and CCMP (counter mode
■
with cipher block chaining message authentication code protocol). CCMP is an IEEE 802.11i
encryption protocol that uses the encryption cipher AES (Advanced Encryption Standard).
Auto is the default.
TKIP only – If you click TKIP only, the Wireless AP advertises TKIP as an available
■
encryption protocol. It will not advertise CCMP.
6 Select WPA v2.
If you select WPA v2, its subordinate Encryption drop-down menu is enabled.
The Encryption drop-down menu offers you the following two options:
Auto – If you click Auto, the Wireless AP advertises both TKIP and CCMP (counter mode
■
with cipher block chaining message authentication code protocol). CCMP is an IEEE 802.11i
encryption protocol that uses the encryption cipher AES (Advanced Encryption Standard).
Auto is the default.
AES only – If you click AES, the Wireless AP advertises CCMP as an available encryption
■
protocol. It will not advertise TKIP.
7 To enable re-keying after a time interval, select Broadcast re-key interval.
If this feature is not selected, the broadcast encryption key is never changed and the Wireless AP will
always use the same broadcast key for broadcast/multicast transmissions. This will compromise the
security for wireless communications.
8 In the Broadcast re-key interval text box, type the time interval after which you want the broadcast
encryption key to be changed automatically. The default is 3600.
