Quick Start Guide Cisco Aironet 1130AG Access Point
Understanding Express Security Settings
When the access point configuration is set to factory defaults, the first SSID
that you create by using the Express Security page overwrites the default
SSID, which has no security settings. The SSIDs that you create appear in the
SSID table at the bottom of the page. You can create up to 16 SSIDs on the
access point.
If you use VLANs on your wireless LAN and assign SSIDs to VLANs, you
can create multiple SSIDs by using any of the four security settings on the
Express Security page. However, if you do not use VLANs on your wireless
LAN, the security options that you can assign to SSIDs are limited because
on the Express Security page encryption settings and authentication types are
linked. Without VLANs, encryption settings (WEP and ciphers) apply to an
interface, such as the 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.
If any VLANs are defined on the access point, the trunk port on the switch
must be limited to allow only the VLANs defined on the access point.
