Quick post today.
Will probably have something to say about my new house, and the options I'm looking at for a NAS / AppleTV streaming appliance eventually.
Have some pictures of my trip to the Kootenay's to post too at some point or something.
So, I keep forgetting how to do this:
How to move bridge-group 1 around on v15 Cisco Aironet's, as they are a pain in the rear. You used to be able to just replace bridge-group 1 with another, but now you get:
Interface already configured within Bridge Group 1.
So that's super helpful. The good news is it can still be moved to somewhere mostly useful. However - the destination interface must be configured with dot1q native. That, of-course, blows big wind. Thanks Cisco!
But hey - at least it's something, and can let the rest of your configs make sense.
To summarize the steps;
- Add Interface.foo subinterface
- Configure for dot1q encapsulation foo native
- Move bridge-group 1 to the new interface.foo subineterface
- Success!
And here it is in action, with gratuitous failure attempts for context.
