Understanding Express Security Settings; Using Vlans - Cisco M10-RM Software Manual

Configuring Basic Security Settings

Understanding Express Security Settings

The SSIDs that you create using the Express security page appear in the SSID table at the bottom of the
page. You can create up to 16 SSIDs on the wireless device. On dual-radio wireless devices, the SSIDs
that you create are enabled on both radio interfaces.
Note
The SSID can consist of up to 32 alphanumeric, case-sensitive, characters.
The first character can not contain the following characters:
•
•
•
The following characters are invalid and cannot be used in an SSID:
•
•
•

Using VLANs

If you use VLANs on your wireless LAN and assign SSIDs to VLANs, you can create multiple SSIDs
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 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.

In Cisco IOS Release 12.4(10b)JA and 12.3(8)JEC, there is no default SSID. You must configure
an SSID before client devices can associate to the access point.
