 Configuring Basic Security Settings
EAP Authentication This option enables 802.1X 
authentication (such as LEAP, PEAP, 
EAP-TLS, EAP-FAST, EAP-TTLS, 
EAP-GTC, EAP-SIM, and other 
802.1X/EAP based products)
This setting uses mandatory 
encryption, WEP, open 
authentication + EAP, network EAP 
authentication, no key management, 
RADIUS server authentication port 
1645.
You are required to enter the IP 
address and shared secret for an 
authentication server on your network 
(server authentication port 1645). 
Because 802.1X authentication 
provides dynamic encryption keys, 
you do not need to enter a WEP key.
Mandatory 802.1X authentication. 
Client devices that associate using 
this SSID must perform 802.1X 
authentication.
If radio clients are configured to 
authenticate using EAP-FAST, open 
authentication with EAP should also 
be configured. If you don’t configure 
open authentication with EAP, the 
following GUI warning message 
appears: 
WA RN ING:
Network EAP is used for LEAP 
authentication only. If radio clients 
are configured to authenticate using 
EAP-FAST, Open Authentication 
with EAP should also be configured.
If you are using the CLI, this warning 
message appears:
SSID CONFIG WARNING: [SSID]: 
If radio clients are using EAP-FAST, 
AUTH OPEN with EAP should also 
be configured.
WPA Wi-Fi Protected Access (WPA) 
permits wireless access to users 
authenticated against a database 
through the services of an 
authentication server, then encrypts 
their IP traffic with stronger 
algorithms than those used in WEP.
This setting uses encryption ciphers, 
TKIP, open authentication + EAP, 
network EAP authentication, key 
management WPA mandatory, and 
RADIUS server authentication port 
1645.
As with EAP authentication, you 
must enter the IP address and shared 
secret for an authentication server on 
your network (server authentication 
port 1645).
Mandatory WPA authentication. 
Client devices that associate using 
this SSID must be WPA-capable.
If radio clients are configured to 
authenticate using EAP-FAST, open 
authentication with EAP should also 
be configured. If you don’t configure 
open authentication with EAP, the 
following GUI warning message 
appears: 
WA RN ING:
Network EAP is used for LEAP 
authentication only. If radio clients 
are configured to authenticate using 
EAP-FAST, Open Authentication 
with EAP should also be configured.
If you are using the CLI, this warning 
message appears:
SSID CONFIG WARNING: [SSID]: 
If radio clients are using EAP-FAST, 
AUTH OPEN with EAP should also 
be configured.
