Configuring WLANs
Note
Web authentication is supported only with these Layer 2 security policies: open authentication, open
authentWEP, and WPA-PSK. It is not supported for use with 802.1X.
Note
The controller supports web authentication redirects only to HTTP (HTTP over TCP) servers. It does not
support web authentication redirects to HTTPS (HTTP over SSL) servers.
Note
Before enabling web authentication, make sure that all proxy servers are configured for ports other than
port 53.
Note
When you enable web authentication for a WLAN, a message appears indicating that the controller will
forward DNS traffic to and from wireless clients prior to authentication. Cisco recommends that you
have a firewall or intrusion detection system (IDS) behind your guest VLAN to regulate DNS traffic and
to prevent and detect any DNS tunneling attacks.
Using the GUI to Configure Web Authentication
Follow these steps to configure a WLAN for web authentication using the controller GUI.

wlan_id
•
Enter
show wlan
to verify that web authentication is enabled.
Assigning a QoS Profile to a WLAN
Cisco UWN Solution WLANs support four levels of QoS: Platinum/Voice, Gold/Video, Silver/Best
Effort (default), and Bronze/Background. You can configure the voice traffic WLAN to use Platinum
QoS, assign the low-bandwidth WLAN to use Bronze QoS, and assign all other traffic between the
remaining QoS levels.
