Cisco Cisco Aironet 1260 Access Point

Express Security page encryption settings and authentication types are linked. Without VLANs, 
encryption settings (WEP and ciphers) apply to an interface, such as the 2.4-GHz radio, and you cannot 
use more than one encryption setting on an interface. For example, when you create an SSID with static 
WEP with VLANs disabled, you cannot create additional SSIDs with WPA authentication because they 
use different encryption settings. If you find that the security setting for an SSID conflicts with another 
SSID, you can delete one or more SSIDs to eliminate the conflict.

 describes the four security types that you can assign to an SSID.

No Security

This is the least secure option. You 
should use this option only for SSIDs 
used in a public space and assign it to 
a VLAN that restricts access to your 
network.

None.

Static WEP Key

This option is more secure than no 
security. However, static WEP keys 
are vulnerable to attack. If you 
configure this setting, you should 
consider limiting association to the 
wireless device based on MAC 
address (see the 

 or, if your network does not 

have a RADIUS server, consider 
using an access point as a local 
authentication server (see 

).

Mandatory WEP. Client devices 
cannot associate using this SSID 
without a WEP key that matches the 
wireless device key.
