In most of the practical scenarios, you have to place a 5760 controller in a existing CUWN (Cisco Unified Wireless Network) environment. In this post we will see how to configure a WLAN on 5760 to support those CUWN setup.

5760-1As shown in the above diagram we will use L3502-2 AP to register to 5760-1 controller. In this case CAPWAP will be terminate on 5760 itself as AP connected to a 3750X series switch where it does not have integrated WLC functionality. Make sure your 5760 has basic configurations (Refer Getting Started with 5760 for detail)

Here is the AP configuration. Let’s delete its NVRAM to forget about previously known WLCs (in this way it will not try to register for previously known WLCs). Then once it boots up, it will get DHCP IP & try to find a WLC. In this example we will configure the WLC IP statically on AP.LAP#debug capwap  con

LAP#debug capwap  console cli

Any configuration change may result in different
behavior from centralized configuration.

Once you configure the 5760 as primary controller for this AP it will successfully register to it.

Now if you look at 5760 end you can see the successful AP registration. We will change the AP name to L3502-2 using “ap name <old_name> name <new_name>” CLI command.

Let’s create a WLAN called “LTUWireless” with open authentication. (In a later post we will change it to dot1x with AAA override). Since I am creating it as open, I do not want to many users connect to it. So I disabled the “broadcast SSID” feature.

5760-1(config)#wlan LTUWireless 21 LTUWireless 
5760-1(config-wlan)#no broadcast-ssid 
5760-1(config-wlan)#client vlan 1420
5760-1(config-wlan)#no security wpa 

Let’s create the dynamic interface for clients on vlan 1420

5760-1(config-if)#do sh vlan brief
VLAN Name                             Status    Ports
---- -------------------------------- --------- -------------------------------
.
.
1410 WLN-STD-6                        active    
1420 WLN-STF-1                        active    
1600 NET-MGT-1                        active 

5760-1(config)#interface vlan 1420
5760-1(config-if)#ip address 10.142.39.253 255.255.248.0
5760-1(config-if)#ip helper-address x.x.x.100 
5760-1(config-if)#ip helper-address x.x.x.200

Now let’s create a AP group called “LTU-CUWN” & put this WLAN onto it. Then you need to add L3502-2 AP onto the group we created.(Note that AP will reboot & register again to 5760)

5760-1(config)#ap group LTU-CUWN 
5760-1(config-apgroup)#wlan LTUWireless
5760-1(config-wlan-apgroup)#?
  default       Set a command to its defaults
  exit          Exit sub-mode
  no            Negate a command or set its defaults
  radio-policy  Configures Radio Policy on given AP-Group
  vlan          Configures the WLANs vlan
5760-1(config-wlan-apgroup)#vlan ?   
  WORD  Specify the vlan name or vlan id
5760-1(config-wlan-apgroup)#vlan 1420

5760-1#ap name L3502-2 ap-groupname LTU-CUWN 
Changing the AP's group name will cause the AP to reboot.
Are you sure you want to continue? (y/n)[y]: y
