Yes. We have some 317's. You use the L2 functions on the Bridge menu,
and the redundant ones on the switch menu seem to have been removed.
You still do port isolation and rate limits under the switch menu. I
would agree that this is less ambiguous, and I hope they migrate that
over to the 2xx.

Adam, have you tried the 300 series of CRS. Supposedly they are a lot
less obtuse on configs for VLANs etc.
We just bought some and are going to put a couple in next week.

That could be a whole thread in and of itself. I've probably got 100
or so CRS's in the field right now, plus 50-100 Mikrotik routers of
one type or another. Usually Tilera or MIPS BE.
First, so you know I'm not a hater I'll list the pros:
* Generally every ROS feature is available on every Mikrotik. When I
lived in Cisco land, it was sometimes frustrated to read about a
feature that I wanted to implement and then find out that it
didn't exist on this platform, or only worked if you had a certain
module installed, or required a different IOS feature track, etc.
* They have two GUI's (Winbox and Web) and a CLI and they're all
very consistent with each other. Clicking
Routing->OSPF->Neighbors is equivalent to typing /routing ospf
neighbors. Cisco sucked at this kind of usability and convenience.
* Almost all models have an industrial temperature spec -40C to
+65C. I sometimes wonder whether it could be an honest spec given
their price point.....but I also never had one die due to
temperature as far as I know.
* Low price
* More or less every feature is there. If ROS can't do something,
then it's something esoteric and you probably don't need it.
* Physically they have low power consumption, wide range DC input
(typically 10-60V), and small size.
Below are the problems that have me questioning my faith in the pride
of Latvian electronics:
* Mysterious problems solved by reboot. It is by no means /common/,
but put enough of these things out there and I promise you'll see
it. Typically there's not enough information to troubleshoot with.
o SNMP stopped working on one unit yesterday. Reboot fixed.
Probably the snmpd stopped, but there was no log message about
it and nothing to indicate what was wrong, and no way to
recover except reboot.
o I've mentioned before, but the CRS will sometimes decide one
day that it doesn't want to pass any traffic to one or more
ports. Reboot fixes. Again no indication of what's wrong
other than it's not working. I have only seen this on 2xx
models, but they may be because that's mostly what we have.
o Other such incidents. And it's pretty much always the
switches, not the routers, doing these things.
* L2 features are obtuse. You now have Interface->VLAN,
Switch->VLAN, and Bridge->VLAN menus. In any given combination of
hardware and software two of these menus are not what you want,
but all three are always present. There are other examples of
duplicate functionality. If you use the wrong menus it may not
work at all, or (worse) it may function as expected but perform
poorly. At least Cisco took away the "wrong" options.
* Documentation tends to be terse. That can be a positive thing
when you already know what you need to do and just need to know
the syntax (as an example), but sometimes I'd appreciate a deeper
dive. Queue trees for example is something where you really want
to experiment to understand what you're dealing with. I'd
appreciate more detailed info on that.
* No central management except whatever scripts you write yourself.
I'm not sure how far I'm willing to test scaling with just pexpect
and some copy pasta, but I think I'm near the limit already. I
realize there's an API, but I'm not inclined to DIY an NMS.
Upgrading ROS on 200 devices is currently a project requiring
multiple maintenance windows across several days. I would pay for
software that automates this.....but such software doesn't seem to
exist.
* Support seems to only be via the forum. I haven't needed much
help with usability, but I wouldn't mind getting assistance with
some of the "mysterious problems solved by reboot" mentioned above.
Also no MEF. I'm reaching a point where some layer2 diagnostics might
be desirable. For example I ran across an ethernet segment where one
customer couldn't get above 50mbps. I was able to narrow it down to a
particular device by a process of elimination, but I'm betting some of
the proper carrier switches have better ways to trouble shoot
something like that (which is why I was looking at Adtran). I still
have feelers out on that.
I guess none of my Mikrotik complaints are insurmountable, but it's
enough to make me look around and check how green the neighbors' grass
looks.

It's hard to argue with those Mikrotik CRS switches for what
you get for the money, but I have my complaints.
I'd like to explore other switches with:
* at least 4 SFP+ ports
* at least 4 SFP ports
* DC input
* Extended temperature range (doesn't have to be -40, but
does need to operate below freezing)
* Smallish size (1/4 depth 1U, or possibly DIN rail)
I have feature wishes too, but just the size and temperature
spec takes 99% of switches out of the mix. What options are
there? I looked at an Adtran Netvanta and loved it.....but
the price tag will knock you out of your chair. Rather than
talk to every switch vendor in the world, I wonder if any of
you guys already found something you like.
