4WirelessModifying Virtual Access Point SettingsTable 16FieldWPA Enterprise Field DescriptionsDescriptionWPA VersionsSelect the types of client stations you want to support:• WPA. If all client stations on the network support theoriginal WPA but none support the newer WPA2, thenselect WPA.• WPA2. If all client stations on the network supportWPA2, we suggest using WPA2, as it provides thebest security by supporting the IEEE 802.11i standard.• WPA and WPA2. If you have a mix of clients, some ofwhich support WPA2 and others which support onlythe original WPA, select both WPA and WPA2. This letsboth WPA and WPA2 client stations associate andauthenticate, but uses the more robust WPA2 forclients that support it. This WPA configuration allowsmore interoperability, at the expense of some security.EnablepreauthenticationIf in WPA Versions you selected only WPA2 or both WPA andWPA2, you can enable pre-authentication for WPA2 clients.Click Enable pre-authentication if you want WPA2 wirelessclients to send a pre-authentication packet. The preauthenticationinformation is relayed from the access pointthe client is using to the target access point. Enabling thisfeature can speed up authentication for roaming clients thatconnect to multiple access points.This option does not apply if you selected only WPA for WPAVersions because WPA does not support this feature.73 Cisco AP 541N Dual-band Single-radio Access Point Quick Start Guide
WirelessModifying Virtual Access Point Settings4Table 16FieldWPA Enterprise Field DescriptionsDescriptionCipher SuitesSelect the cipher suite you want to use:• TKIP• CCMP (AES)• TKIP and CCMP (AES)By default both TKIP and CCMP are selected. When bothTKIP and CCMP are selected, client stations configured touse WPA with RADIUS must have one of the following:• A valid TKIP RADIUS IP address and RADIUS Key• A valid CCMP (AES) IP address and RADIUS KeyActive ServerDisplays which RADIUS server is in use. You can manuallychange from this server to a different server by selecting thedesired server in the dropdown box.NOTE: The Active Server is not stored across reboots. Thefirst configured RADIUS server is selected when the deviceis rebooted or reset.Use GlobalRADIUS ServerSettingsBy default each VAP uses the global RADIUS settings thatyou define for the access point at the top of the VAP page.However, you can configure each VAP to use a different set ofRADIUS servers.To use the global RADIUS server settings, make sure thecheck box is selected.To use a separate RADIUS server for the VAP, clear the checkbox and enter the RADIUS server IP address and key in thefields.RADIUS IPAddressRADIUS IPAddress 1–3Enter the address for the primary RADIUS server for this VAP.Enter up to three IPv4 addresses to use as the backupRADIUS servers for this VAP.If authentication fails with the primary server, eachconfigured backup server is tried in sequence.Cisco AP 541N Dual-band Single-radio Access Point Quick Start Guide 74
