Finding the IP Address Using the CLI
Using the Express Security Page
Follow these steps to create an SSID using the Express Security page:
Step 1
Type the SSID in the SSID entry field. The SSID can contain up to 32 alphanumeric characters.
Note
These characters are not allowed in the SSID: ?, ", $, [, \, ], and +. In addition, these characters
cannot be the first character: !, #, and ;.
cannot be the first character: !, #, and ;.
Step 2
To broadcast the SSID in the bridge beacon, check the Broadcast SSID in Beacon check box. When you
broadcast the SSID, devices that do not specify an SSID can associate to the bridge. This is a useful
option for an SSID used by guests or by client devices in a public space. If you do not broadcast the
SSID, client devices cannot associate to the bridge unless their SSID matches this SSID. Only one SSID
can be included in the bridge beacon.

(Optional) Check the Enable VLAN ID check box and enter a VLAN number (1 through 4095) to assign
the SSID to a VLAN. You cannot assign an SSID to an existing VLAN.

Step 4
(Optional) Check the Native VLAN check box to mark the VLAN as the native VLAN.
Step 5
Select the security setting for the SSID. The settings are listed in order of robustness, from No Security
to WPA, which is the most secure setting.

If you select Static WEP Key, choose the key number and encryption key size and enter the
encryption key (10 hexidecimal characters for 40-bit keys or 26 hexidecimal characters for 128-bit
keys).

Note
If you do not use VLANs on your wireless LAN, the security options that you can assign to
multiple SSIDs are limited. Refer to the Cisco IOS Software Configuration Guide for Cisco
Aironet Access Points for VLAN details.

Step 6
Click Apply. The SSID appears in the SSID table at the bottom of the page.
Finding the IP Address Using the CLI
When you connect the access point to the wired LAN, the access point links to the network using a bridge
virtual interface (BVI) that it creates automatically. Instead of tracking separate IP addresses for the
access point’s Ethernet and radio ports, the network uses the BVI.

To find the IP address of your access point using the console port, you can use the Cisco IOS CLI show
ip interface brief bvi1 from the privileged EXEC mode. For additional information on the CLI, refer to
