From this i take is that you are using the avaya networking gear with
the fcoe protocol enabled, this is a big no-no. you need to disable

it is not about lops at all, nor is it about looping, its all about the

if the step above failed, i would take the cable that is plugged into

There is some deployable technology that allows some aspects of this today.
Yes, it's in its infancy. Small prefix limitations will guarantee it never sees
the
light of day just as NAT precluded many useful innovations from getting
deployed.
Layer 3 isolation is only isolation by agreement if the hosts have some way
to get on the same physical or logical LAN layer 2 segment. Otherwise, layer 3
isolation is as effective as any firewall. Layer 2 isolation, OTOH, is both
harder to administer and no more effective than layer 3. If you can bypass
layer 3
by connecting to the same LAN segment, chances are you can bypass layer 2
by making that LAN segment one which doesn't go through the enforcement
switch between the two devices in question.

Not necessarily nibble aligned, but, multiple bits per level, yes.

If we are stingy in address allocations, it will stifle such innovations as
the vendors tend to develop to the lowest common denominator. If we
make the allocations available, innovative ideas will make use of them.

No, it is not true.
I suppose that limiting enough households to too small an allocation
will have that effect. I would rather we steer the internet deployment
towards liberal enough allocations to avoid such disability for the
future.
Have we learned nothing from the way NAT shaped the (lack of)
innovation in the home?

Is there an acronym for RTFM when there are a volume of manuals that need to be
read?
