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 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 Enterprise – Select this and the AP uses the global RADIUS

server or the specified RADIUS server for the wireless network.

• 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.

Client QoS

Tick the check box to enable Client QoS operation for wireless clients that
