Client QoS
WPA/WPA2 WPA and WPA2 are Wi-Fi Alliance IEEE 802.11i standards, which
include AES-CCMP and TKIP mechanisms. Select WPA/WPA2 to
see the following options.
WPA Personal – Select this to configure static key management.
•
•
•
•
•
WPA Enterprise – Select this and the AP uses the global RADIUS
server or the specified RADIUS server for the wireless network.

Tick the check box to enable Client QoS operation for wireless clients that
WPA Versions – Tick the check boxes to select the types
of client stations to support. Available options are WPA and
WPA2.
WPA Ciphers – Tick the check boxes to select the cipher
suite to use. Available options are TKIP and CCMP (AES).
WPA Key Type – The key type is ASCII, which includes
upper and lower case alphabetic letters, the numeric digits,
and special symbols such as @ and #.
WPA Key – The WPA Key is the shared secret key for WPA
Personal. Enter a string between 8 and 63 characters.
Acceptable characters include upper and lower case
alphabetic letters, the numeric digits, and special symbols
such as @ and #.
Bcast Key Refresh Rate – Enter a value to set the interval
at which the broadcast key is changed for clients associated
to this VAP.
WPA Versions – Tick the check boxes to select the types
of client stations to support. Available options are WPA and
WPA2.
WPA Ciphers – Tick the check boxes to select the cipher
suite to use. Available options are TKIP and CCMP (AES).
Pre-Authentication – Tick the Pre-Authentication check
box to allow WPA2 wireless clients sending
preauthentication packets. The pre-authentication
information is relayed from the access point. The client is
currently using to the target access point. Enabling this
feature can help speed up authentication for roaming clients
who connect to multiple access points. Only clients that
connect by using WPA2 can use this feature. It is not
supported by the original WPA.
Pre-Authentication Limit – Enter the number of pre-
authentications that can be in progress simultaneously on
an AP. The limit prevents too much load on the RADIUS
server. This does not prevent the preauthentication from
being attempted again when the load is lighter. A value of 0
represents no limit.
Key Caching Hold Time – Enter the amount of minutes a
PMK will be held by the AP. This applies to Pairwise Master
Keys (PMKs) generated by RADIUS, those that come from
pre-authentication, and those that are forwarded to the AP.
Note that this time limit can be overridden by RADIUS if the
RADIUS server returns a longer time in the Session-
Timeout attribute for a particular user. The valid values of
this are from 1–1440 minutes. If you do not enter a value,
APs will not forward the PMK for the wireless client to other
APs in case the client roams to another AP.
Bcast Key Refresh Rate – Enter a value to set the interval
at which the broadcast (group) key is changed for clients
associated to this VAP.
Session Key Refresh Rate – Enter a value to set the
interval at which the Unicast session keys is changed.
