hi,
I'm starting a design of a redundant link from the office to our warehouse.
distance is 1 mile, and already running a 50Mb 5GHz wifilink.
What I want to do is to make this fully redundant, with a 2nd wifi link, trunked
(and use data and voice over it, vlans and QOS)

Please advice how to connect this to our cisco 3560 switches + what protocols are handy and needed.

site A site B
LAN -switchA1 -> wifi link 50Mb -> switchB1- LAN
|* |*
LAN -switchA2 -> wifi link 50Mb -> switchB2- LAN

* is a portchannel
Is it possible to make the whole config like one 'portchannel'?
So that in every scenario a wire, a link, antenna or a switch may fail.
(The link speed may drop from 2x 50Mb to 1x 50Mb)

The point I think is: portchannel redundancy only works when a switch loses a link. But lots of scenarios are possible: the switch thinks that the link is still UP if the antenna is blown away. It's a high building;-)
So I need a protocol that does a 'ping' from switchA1 to B1, and if that does not reply, that shut down the link and route all traphic from switchA1 to B1, to B2 etc.
