Hi all,

I got a Cisco 1200 series wi-fi router. My requirement is to have an ssid for guests and also another ssid for our employees.

My setup is like below:







Layer 3 Switch



Aironet wi-fi

If I connect the wifi to a LAN and with no vlan concept, I am able to get the laptops connected to the wifi to an ssid.

My requirement is to bring in the vlan concept. In my layer 3 switch I have  trunk port configured. Now my wifi has no configuration. What is the next step I should follow? What is the IP sI should give to the wifi BVI interface and also, how can I get all vlan's in the layer 3 switch to the wi-fi so that I can assign particular vlan's to the guests and employees.

Let me know if my concept is wrong. Thanks for any response.

Thanks for the doc Rob.

I was following the configuration using GUI.

In my Layer 3, I have three vlan's,, and I connected the wifi in network with IP and did some configurations. I created an ssid for guests, assigned vlan 3. In the Layer 3 switch I created a trunk port also and connected a cable from the trunk port to the a=fastethernet port of the wifi.

Right now, a laptop user can connect to the wifi and the laptop takes an IP in the range 192.168.3. . But right now, i am not able to get the GUI of wifi which was earlier being accessed using I think I am missing something with the vlan/native vlan configuration. Any idea what it could be?

Also, how can I broadcast multiple ssid's? When I tried to enter a 2nd ssid, it showed "Dot11Radio0: Guest-ssid already existing on ssid".

I solved the previous issue using mbssid command. Any help with the vlan config?

Hi Ribin,

So the BVI interface on the AP is asigned the IP address and the laptop is getting the IP from 192.168.3.X network and the client is not able to access the GUI if we connect to the vlan 3??

>> lets try pinging the ip of vlan 1 from the laptop and also from AP to vlan 3 and lets see if both are success

>> Configure VLAN 1 as native on the AP and then try accessing..
