Table 14. Static WPA

FieldDescription

Pre-AuthenticationIf you select WPA/WAP2 Enterprise, you can enable Pre-Authentication.

Click the Pre-Authenticationcheck box if you want WPA2 wireless clients to send pre-authentication 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-AuthenticationEnter the number of pre-authentications that can be in progress

Limitsimultaneously on an AP. The limit prevents too much load on the RADIUS server. This does not prevent the pre-authentication from being attempted again when the load is lighter. A value of 0 represents no limit.

Note: This field is only available if you access the network through the AP Profile or Network page under Advanced Configuration.

Key Forwarding Select the check box to allow APs to forward the Pairwise Master Key (PMK) for the wireless client to other APs in case the client roams to another AP.

Note: This field is only available if you access the network through the AP Profile or Network page under Advanced Configuration.

Key Caching Hold Enter the amount of minutes a PMK will be held by the AP. This applies to

TimePMKs 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.

Note: This field is only available if you access the network through the AP Profile or Network page under Advanced Configuration.

Configuring Valid Access Point Settings

You can add an AP into the list of Valid APs from the Administration > Basic Setup > Valid AP tab, as Figure 45 shows, or you can add an AP from the AP Authentication Failures or Rogue AP/RF Scan lists.
