Client QoS DWS-3160 Series Gigabit Ethernet Unified Switch Web UI Reference Guide 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 preauthentications 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 SessionTimeout 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. Tick the check box to enable Client QoS operation for wireless clients that 398
