Configuring WPA PSK Security
Table 54. WPA PSK Security Parameter Descriptions
Parameter Explanation
Multicast
Encryption Type
Indicates that TKIP is used as the data encryption
method for broadcast and multicast for this radio
port. A station connected to this port may not
select a weaker encryption method to exchange
unicast frames.
Pre-shared Key Allows you to enter the pre-shared key for WPA.
You can enter a 256 (32 byte) hexadecimal value
or up to a 63 character ASCII passphrase. To
enter a hexadecimal key, start the value with 0x
and follow it with 64 hexadecimal digits. If you
omit the 0x, the value is treated as an ASCII
pass-phrase and the key is derived from the
pass-phrase using the PBKDF2 algorithm.
A short PSK is not as secure as a long PSK.
Key Rotation
Period (Minutes)
Allows you to specify the key rotation policy for
encryption keys when using WEP in 802.1x and
for TKIP group keys when using WPA. The value
represents key duration in minutes. The default
value is 5 minutes.
