Sent a tech to the site and he says... none of the (GigE | FastE) ports
show a link. Power-cycle, fixed. Happened again a couple hours later so
we replaced it.
The another one, he gets there and says the FastE ports show a link but
there's no traffic. Power-cycle, fixed. That one I don't think we had to
replace.
Other times, a port or two won't work. Link might come up or not, I
don't remember. I saw this with a brand-new one out of the box. Again,
power cycle = fix. It's really random and stupid.
Upgraded ROS on a few one time. Couple hours later, two of three
crashed. So now I don't touch them. If one needs to be updated, I load a
new one and just swap it out.

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.
