Cisco Cisco Aironet 1240 AG Access Point Guía De Instalación

Because the Express Security page is designed for simple configuration of 
basic security, the options available are a subset of the access point security 
capabilities. Keep these limitations in mind when using the Express Security 
page:

You cannot edit SSIDs. However, you can delete SSIDs and recreate 
them.

You cannot assign SSIDs to specific radio interfaces. The SSIDs that you 
create are enabled on all radio interfaces. To assign SSIDs to specific 
radio interfaces, choose Security > SSID Manager.

You cannot configure multiple authentication servers. To configure 
multiple authentication servers, click Security > Server Manager.

You cannot configure multiple WEP keys. To configure multiple WEP 
keys, click Security > Encryption Manager.

You cannot assign an SSID to a VLAN that is already configured on the 
access point. To assign an SSID to an existing VLAN, choose Security 
> SSID Manager.

You cannot configure combinations of authentication types on the same 
SSID (such as MAC address authentication and EAP authentication). To 
configure combinations of authentication types, choose Security > 
SSID Manager.
