and some other models.

I've had many 2011's appear to crash for no apparent reason. Come to
find out, the switch controllers are what crash from time to time.
Sometimes all of the GigE ports stop working, other times it's the
FastE ports. I'm not a fan of the 2011s at all.

Yeah, likely the customers media converters are not Gig capable,
they are pretty old, it was disconcerting not to be able to talk
at 100M or even 10M though. I’m more worried that it doesn’t
seem to talk to a CTM-2 on a GigE port. And who knows what else.

What ROS/Routerboard version? Does the customers Media converter
auto-negotiate, or does it only work at 1 speed? It's been a
while since I've used them, but the 1G converters I had were only
1000base on the Ethernet port, no auto.

Yes, in this case the MT interface reported successfully

Well....autonegotiation failures happen sometimes, but
typically those work ok when you force the speed on the
link. In the case I'm thinking of, we could not get a
working link no matter what. It was quite awhile ago now, but
I think it would report a link was up while the input
counters never climbed above 0.
We have a couple devices that don't work with Mikrotik
devices at all. Putting a switch in between fixes it
but not ideal.

Yes...maybe. We had somebody not able to get link
with an RB2011. I don't think we ever tried the
10/100 ports. The customer ended up getting a
different router.
Is there an issue with the GigE ports on Mikrotik
RB2011 not talking to some
devices no matter what settings you try? I had
this with a customer's
copper/fiber media converter, moved it to a
10/100 port on the 2011 and all
was good. Now I think I'm seeing the same thing
with a CTM. Setting the
GigE port to only negotiate 100M didn't work, no
amount of playing with the
settings worked, had to physically move it to a
10/100 port.
If this is a known problem and not my
imagination, what other Mikrotik
devices share this issue? If this had been an
1100 or CCR or CSR, I might
not have had a 10/100 port available and I would
have been stuck.
