Replicating a Wireless Setup across heterogeneous APs...

Hello,

Thanks for all of the help provided in previous threads. I am trying now to deploy the setup that works on some APs and doesn't work on others.

For example, on an AIR-AP1231G-A-K9, the following setup works:

But on a AIR-AP1220-IOS-UPGRD (Basically an AP Aironet 1220 with an IOS upgrade), the following setup does not work - neither network connects, even though I tried to make them as similar as possible:

I have both ports connecting to identical port configurations as follows:

interface GigabitEthernet 0/47

switchport trunk encapsulation dot1q

switchport trunk native vlan 60

switchport mode trunk

!


What changes do I need to make to 12.2 IOS and older APs to recognize and use multiple networks?

Thanks.

You need to assign a different bridge group id to each VLAN on both the radio and ethernet interfaces. You assigned the same IP address to the Fast Ethernet0.60 Interface and the BVI1 interface. You also assigned an IP Helper to the FastEthernmet0.60 Interface and the BVI Interface. Only the BVI1 interface needs an IP address for mangement of the AP. The IP helper should be assigned to the L3 interface on your router or switch to forward the DHCP requests. I would also recommend not using a VLAN for management of the AP that is assigned an SSID especially on the Public/Guest WiFI. It also looks like the 1200 AP is on 12.3 from the listing.

Here is a partial configuration example below for multiple VLANS.

Chris,

Just like the previous thread, you are trunking to your switchport. I believe there is a L3 switch somewhere to do the routing for vlan 60 and 70.The IP helper can be assigned in the L3 switch for those vlans.

Remove the IP address from BVI1 and shutdown it. Assign the ip address in Fas0.60 in both the AP's. Choose the lease congested channel and it should work fine. We got this setup for all our autonomous system AP's and works without any issues.
