Configuring WPA PSK Security

Table 54. WPA PSK Security Parameter Descriptions

Parameter	Explanation
Multicast	Indicates that TKIP is used as the data encryption
Encryption Type	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	Allows you to specify the key rotation policy for
Period (Minutes)	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.
