Ok we have two switches to with the Server 2012 is connected with two nics and two cables.

They are not stacked but have a UTP cable with vlans trunked between them.

Both switches are also have each 2 uplinks to 2 other switches

Microsoft says that if they are stacked you should use dependent mode for teaming. Now that they are trunked, not stacked, should independent mode still work ok for both 2 nics in active/active config ? Or will stp if configured close one of the ports on 1 of the switches because I guess same ip/mac is seen on both switches causing loops ?

when switches are stacked, they work as a single switch. This means you can use clever teaming facilities like LACP to combine traffic between different NICS across switches. This works because the switches are all aware of the dual connections and can deal with them correctly.

Without teaming each switch is working independently without knowledge of whats connected to other switches, and therefore only more basic types of teaming can be used.

Using this basic version of teaming (switch independent) you don't get as many features and it doesn't load balance as well as other types of teaming.
In a nutshell, both NICs pretend to share a single MAC address, and the switches just route traffic to the appropriate ports in a fairly inefficient way.
