Step 1 - Connect to the AP
Step 2 - Setup Wizard
- IP address of the Mobility Express management interface: 192.168.88.11/24 (Note: The IP address of the Mobility Express controller has to be different from the AP IP address!!)
- IP address of the gateway: 192.168.88.1
- DHCP server for the Wi-Fi clients: 192.168.88.100-200
- Host name of the controller: surveyWLC
- Admin credentials: Admin / Cisco123
Here is how I configured mine (these parameters can be changed to match your environment):
- show interface summary
- show time
- show dhcp summary
Step 3 - Configure the survey SSIDs
- Open SSID called survey24 on the 2.4GHz band only
- Open SSID called survey5 on the 5GHz band only
Here is how you can configure them on the Mobility Express controller via CLI:
- show wlan summary
- show wlan wlan_id
Step 4 - Radio Settings
Use the show config ap 802.11b ap_name and show config ap 802.11a ap_name commands to find out which power level corresponds to which dBm value for your AP.
First, you need to make sure that the AP joined the controller using the show ap summary command. In our case the name of the AP was surveyAP. If the AP didn't join, make sure that you are using different IP addresses for the AP and the Mobility Express controller. Also, check out this article from Packet 6: Troubleshoot AP Joining Issues - Cisco Mobility Express.
Here is how you can configure these radio settings on the Mobility Express controller via CLI:
If you try to configure the 802.11-abgn radio the same way we configured the 802.11b radio above, you will get the following error:
We need to change the role to manual client-serving in order to be able to configure the custom transmit power.
Here is how to configure the 802.11-abgn radio:
- show ap summary
- show advanced 802.11b summary
- show advanced 802.11-abgn summary
- show advancde 802.11a summary
- show ap config 802.11b ap_name
- show ap config 802.11-abgn ap_name
- show ap config 802.11a ap_name
Step 5 - Validations
As a validation, I try to associate to both SSIDs and wait to receive an IP address.
Here are a few commands that you could use on the Mobility Express controller to validate the client connections:
- show client summary
- show dhcp leases
Don't forget to save your configurations using the save config command.
You are all set!
