Brian,
Ciscos use per-vlan spanning tree, so you won't get a loop. Out of
the box though, you won't get any load balancing either. Modifying port
cost between the ports on different VLANs can get you some load balancing,
where VLAN x uses port y, VLAN a uses port b, but never a single VLAN using
more than 1 port. Etherchannel's the best though, as you get load balancing
and redundancy.

>Suppose we have a 3550 and a 5000 switch and we configure 4 trunk ports
between them. Will traffic be load balanced across the 4 trunks without
creating an etherchannel? Assume all 4 trunks carry the same VLANS. Are we
creating a loop without the Etherchannel?
