Thanks all, I completely agree with you and you have confirmed my initial
assessment of their system. Now the fun part, letting my client know they
have wasted 2 years and several million dollars on a custom
hardware/software solution that is terrible.

I remember seeing something like a 4 port switch pci card a few decades
ago, but they're simply not useful anymore when you can buy a 4 port gig
switch for 5 bucks from china now.
Any other 2-4 port card treats them as standalone nics each, and really
aren't meant to be bridged together on a
I'll have to look. But I think there are ethernet controllers with small
switching fabric in them.
That might be a level of scaling that would maybe work.

Awesome responses, I'm still digesting the information. The original ring
idea was not mine but they decided to do this because of simplicity and
redundancy, both are requirements. The system is an embedded device and
they even made custom Ethernet "cards". When I initially looked at the

You're right about RSTP, but the daisy chaining hosts thing is just bad
mojo in general. Some random host between to others conversion gets wonky,
you have to figure out which
It appears that some buttons were pushed. My initial reading did suggest
rstp was very good to maintain switch to switch redundancy, which is what i
initially thought. Re reading your initial email I am still very curious
about why you were looking to use rstp as a nic to nic design.

an experiment to say they can/did. Host ethernet chaining is not what

That was a great explanation David, thanks!
Wasn't my question, but I certainly learned a lot.

I’d advise against it without finding someone who’s already done it and is
willing to share the details about how they made it work, and what their
throughput stats are like. (Their stats could be horrible, but they don’t know
and don’t care simply because their needs are being met.)

I am still wrapping my head around why this was the root design.
I am not sure what gains you have vs having a pair of switches for
redundancy. time to research RSTP.

Looking for some networking advice from the group.
The system I have has several devices connected in a ring configuration
using one Ethernet port IN and one Ethernet port out. The system uses RSTP
for loop free operation. The idea is simplicity for installation, you just
