If it down's on link-lost, and link is asserted only if up, then BSD to BSD will have a hard time coming up. Both of them would have to assert at the same time (unless you limit it to on-to-off link transition). Even then, you would need to set the link up manually on both sides. I guess I just don't get the value of downing the link, ever. Terry Lambert terry@lambert.org --- Any opinions in this posting are my own and not those of my present or previous employers.
