Switches are beleaving to see a loop and > disable one port. We use such setup with our Sun machines and Cisco switched and it seems to work fine (i.e. it fails over if one switch is powered-off). Note: ports on both switches are in the same network/natmask. I am looking for similar solution for FreeBSD as it is otherwise difficult to defend use of FreeBSD as an optional (also reliable ) platform.
