Lab 6-2 Configuring a WLAN Controller via the Web Interface

Topology Diagram

Scenario

Continuing from the previous lab, you will now set up the WLAN controller
through its web interface. In the previous lab, you configured it through the
command line interface.

Step 1

Set up all the switches as they were in the previous lab. Make sure that the
WLAN controller and host also have the same configuration as before.

Step 2

On the host, open up a browser and go to “https://172.16.1.100”. This is the
secure method of connecting to the management interface of the WLAN
controller. You can also use “http://172.16.1.100” because we previously
enabled regular insecure HTTP access in Lab 6.1. If you connect to the secure
address, you may be prompted with a security warning. Click Yes to accept it.
You are then presented with the login screen for the WLAN controller. Click
Login and an authentication dialog box appears.

Authentication Dialog Box for WLAN Controller Web Access

Use “cisco” as both the username and password, which you configured in the
previous lab. Click OK. The monitor page for the WLAN controller appears.

WLAN Controller Monitor Page

Make sure that you see two access points under Access Point Summary. You
may also see it detecting rogue access points if your lab has other wireless
networks around it; this behavior is normal. You can view various port controller
and port statistics by clicking their respective links in the menu on the left side
of the screen.

Step 3

Add the logical interfaces on the WLAN controller that correspond to VLANs 2
and 3. First click Controller at the top of the page, and then click the Interfaces
link on the left side.

Interface Configuration Page

Click New to create a new interface. Name the new interface VLAN2 and use 2
for the ID. Click Apply to submit the parameters.

Creating a New VLAN Interface

On the next page, configure the IP address shown in the diagram. Also
configure this on physical port 1, because that is the port trunked to the switch.
After you have made your changes, click Apply. Click OK to the warning stating
that there may be a temporary connectivity loss on the APs while changes are
applied.

Configuring VLAN Interface Properties

The new interface should appear in the interfaces list. Repeat the configuration
steps for VLAN 3.

Verifying VLAN Interfaces on the WLAN Controller

Step 4

Configure the WLANs that correspond to the VLANs. Click WLANs at the top of
the page to view all the configured WLANs.

Viewing Existing WLANs

Click Edit to the right of the WLAN, and then remove Layer 2 security and
change the interface to VLAN2. This associates the WLAN with the correct
VLAN.

WLAN 1 Without a Security Policy

Click New to configure a WLAN for VLAN 3. Use the SSID “ccnplab.”

Adding a New SSID for WLAN 2

On this WLAN, configure the Layer 2 security as Static WEP and use a 40-bit
WEP key. Make the key index 2 and use a key of “cisco.” Also set the
administrative status of the WLAN to enabled and change the interface name to
VLAN2. When you are done, click Apply. You should see both WLANs in the
WLAN list.

Verifying Final WLAN Configuration

If you have a computer with a wireless card installed, you should see both
SSIDs and be able to connect to the WLANs/VLANs associated with them.
Notice that each WLAN exists in a separate subnet, because each WLAN is in
a separate VLAN.s
