Configuring Wireless Quality of Service
Configuring Quality of Service (QoS) can provide preferential treatment to certain traffic at the expense 
of other traffic. Without QoS, the device offers best-effort service to each packet, regardless of the packet 
contents or size. It sends the packets without any assurance of reliability, delay bounds, or throughput. 
To configure quality of service (QoS) for your wireless device, see Quality of Service in a Wireless 
Environment at: 
http://www.cisco.com/en/US/docs/routers/access/wireless/software/guide/QualityOfService.html.
EAP

 Authentication This option enables 802.1X authentication (such as 
LEAP

, EAP-TLS

, EAP-TTLS

, 
EAP-GTC

, 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 do not 
configure open authentication with 
EAP, the following warning message 
appears:
SSID CONFIG WARNING: [SSID]: If 
radio clients are using 
EAP-FAST, AUTH OPEN with EAP 
should also be configured.
WPA

This option 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
10
, 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 message appears:
SSID CONFIG WARNING: [SSID]: If 
radio clients are using 
EAP-FAST, AUTH OPEN with EAP 
should also be configured.
1. EAP = Extensible Authentication Protocol.
2. LEAP = Lightweight Extensible Authentication Protocol.
3. PEAP = Protected Extensible Authentication Protocol.
4. EAP-TLS = Extensible Authentication Protocol - Transport Layer Security.
5. EAP-FAST = Extensible Authentication Protocol-Flexible Authentication via Secure Tunneling.
6. EAP-TTLS = Extensible Authentication Protocol-Tunneled Transport Layer Security.
7. EAP-GTC = Extensible Authentication Protocol--Generic Token Card.
8. EAP-SIM = Extensible Authentication Protocol--Subscriber Identity Module.
9. WA = Wi-Fi Protected Access.
10. TKIP = Temporal Key Integrity Protocol.
