Configuration of vLAN subinterfaces and main interface withing the same bridge group is not permitted.

To who can help,

 

I'm trying to get my wireless to work. I'm basically trying to configure the Dot11radio 0. Based on an old post, I believe it said something to the extent of, when doing subinterfaces, the subinterface can't be on the same interface as the main one, so I have the dot11radio0 interface in a Bridge-Group 1, and the sub-interface which I called dot11radio0.1 in a Bridge-Group 2.

 

What I tried to do was make a new Bridge-Group 2, I tried doing a new vlan, but I know vlan1 is the vlan associated with the ethernet ports, and a new BVI2 to join everything. I also created a new DHCP pool for the BVI. I also created routes from and to where the traffic is going.

 

The final results was, the DHCP worked, but I couldn't get to the internet. I'm new to this, so I'm sure that I hosed a few things,  but I wanted to give it a try before I asked for help.

 

Any help will be greatly appreciated, regards.

Hi Woodstar,

 

I think it should be helpful.

you need add a "native" in every subinterface. 

e.g.

interface Dot11Radio1.820
encapsulation dot1Q 820 native

"so I have the dot11radio0 interface in a Bridge-Group 1, and the sub-interface which I called dot11radio0.1 in a Bridge-Group 2."

When you creating sub-interfaces, normally you do not assign bridge-group 1 to the main radio interface. Instead, it should be under a sub-interface configured for your native VLAN.

 

Read the initial part of this post and you understand what I mean
