Basic interface configuration
Configure VLAN 1 with an IP address and associate wlan-ap0 with it.
Router#<input>conf t</input>
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#<input>ip route 0.0.0.0 0.0.0.0 192.168.1.1</input>
Router(config)#<input>int vlan 1</input>

Router(config-if)#<input>interface wlan-ap0</input>
The wlan-ap 0 interface is used for managing the embedded AP.
Please use the "service-module wlan-ap 0 session" command to console into the embedded AP

The access point - AP -wlan-ap0 is a built in service module running its own IOS. To connect to the AP use the service-module command from the Routers IOS.
Connecting and disconnecting to the AP
Connecting
To connect use the service-module command
Router#<input>service-module wlan-ap 0 session</input>
Trying 192.168.64.4, 2002 ... Open
Connecting to AP console, enter Ctrl-^ followed by x,
then "disconnect" to return to router prompt

ap#Notice the BVI11 interface pulls an IP address from a connected DHCP server.
Disconnecting
To disconnect from the AP back to the router use the sequence press<CTL>+<SHIFT>+6 simultaneously and the press x after.

Closing connection to 192.168.64.4 [confirm]
Router#Assigning an IP address interface to BVI 1
The BVI 1 interface is Brigded Virtual Interface used to bridge packets between interfaces in the same subnet on a router. We would want a fixed IP address on this interface.
<notice>! NOTICE: This is the AP we are configuring</notice>
ap(config)#<input>interface BVI 1</input>
ap(config-if)#<input>ip address 192.168.64.5 255.255.255.0</input>Secure AP web server with HTTPS
The AP can be configure from the CLI or the web server
Disable the default http server and enable https. You should also change the default user and password - not shown here.
<notice>! NOTICE: This is the AP we are configuring</notice>
ap(config)#<input>no ip http server</input>
ap(config)#<input>ip http secure-server</input>Connecting to the AP from the browser
Connect to https://192.168.64.5 and accept insecure certificate, and you should see the homepage. (Default username Cisco password Cisco)
Notice the three interfaces
- GigabitEthernet corresponds to GigabitEthernet0 in the config
- Radio0-802.11N corresponds to Dot11Radio0 in the config (2,4 GHz radio)
- Radio1-802.11N corresponds to Dot11Radio1 in the config (5 GHz radio)
In the following example the AP will be configured from the CLI - just for the fun of it - but it could as well has been configured from the web server.
Configuring SSID
In this example WPA security is used and the SSID is broadcasted in the beacons.
Security
The authentication open means that WPA authentication is used, and any wireless device that knows the encryption key could associate with the AP. The guest-mode means the SSID is broadcasted in the beacon frames.

The SSID is associated withe the interface and the WPA key is assigned on the interface as mandatory.
