I have seen other strange things on the ICX7750, the most concerning
of which is a temporary forwarding loop on an MCT LAG during every
boot.

The code still seems a bit immature...

Eldon,

Our Brocade reseller is aware of the issue you're describing and says it's
being worked on. He's asking what code release you're on and if it's 10G or
40G specific.

I noticed it on the 8010. I moved to 8020aa and disabled loop
detection on our peer switches, at which point I promptly forgot about
it and went on with life ;).

We are currently running 8030b, but I haven't had a chance to check to
see if it is fixed (I don't have any of them for our lab environment,
and I don't want to cause an outage).
