Basic switch config with double trunk between two switches?

Hi all,

I'm having a bit of a tough time grasping the methodology of Cumulus Linux networking vs. how I'm used to with "simple L2 switches".

So here's my question:
  I have two SuperMicro switches running Cumulus Linux (3.3.1) - freshly installed. These two switches are replacing two older Procurve swithces. These two are located in separate cabinets and trunked together. The procurves with a single trunk, but my plan was to use two of the 4 10Gbit ports on the SuperMicro as trunk ports between the switches.

What would be simplest "up and running with NO VLANs (or "default") active at the moment and an active trunk between sw01[swp49,swp50] and sw02[swp51,swp52] ? All interfaces should connect to all other switch ports.. (this is a "I got to get this thing up and running now, and add extra features later" plead :) )

Thanks in advance!

Ok, so I really don't sound like I'm trying to get a free lunch (well, sort of I am...) I've already tried this:

attempt #1:
  net add interface swp1-52
  net add int swp49-50 bridge trunk

and attempt #2 (after clearing the config):
  net add interface swp1-52
  net add int swp1-52 bridge bridge

This done on both switches - but I couldn't get any sense into them - machine A connected to sw1 cannot ping machine B on sw2.

net add int swp1-52 bridge vids 1
net add bridge bridge pvid 1

Which is the same thing as /etc/network/interfaces - 
auto bridge
iface bridge
    bridge-ports glob swp1-52
    bridge-vids 1
    bridge-pvid 1

bridge-ports is the list of interfaces on the bridge.
bridge-vids is the list of vlans available to the bridge.
bridge-pvid is the native (untagged) vlan.

I think you might run into issues though with spanning-tree since you have multiple interfaces between the two switches.
