BTW, how do u guys can confirm that there no port flapping under SwOS? I didnt find any log section in SwOS web interface...

You have to check it on 328 side, looking for disconnections or rstp recalculation

Re: Severe port flapping on CRS328-24P-4S+ and CRS317-1G-16S+

So seems like the problem is with CRS317-1G-16S+
We have one CRS317-1G-16S+ in center and three CRS317-1G-16S+ at remote ends, after 6 days from reboot we got port flapping - but not on all ports, we tried to change SFP+ modules, cables but no sense. After we changed from RoOS to SwOS on central CRS317-1G-16S+ log files of the remote CRS317-1G-16S+ (that are still running RoOS) are showing no port flapping after more than 8 days!

I can confirm that the problem appear also with 2 CRS317 connected trought mk DAC.
PLEASE MIKROTIK, GIVE US SUPPORT!!!!!!!!!

I confirm the problem with the CRS328 and CRS317 connection.
The problem is partially solved by the change of the CRS317 system to SwOS. But still Rx FCS Errors occur on the 10G interfaces.

Mikrotik, this issue has almost 6 months !!

It seems that Mikrotik acknowledges the problem, my reseller confirmed this point, you should be able to prioritize this issue as it affects core features : we're unable to deliver 10G connectivity !!

We can confirm the same, but not on all interfaces, those that were stable on RoOS have only 2 Errors.

Can anybody try to add attenuators on problematic links? Would it change anything?

That seems unlikely as I have the same link flapping on my DAC links btween the CRS328 and CRS317 on 10G links. Something seems to be wrong (software or hardware??), but Mikrotik does not seem to be interested...

Yes
This is the setup on my desk. It does nothing, only connections between switches.

We are having this issue as well between two CRS317-1G-16S+ in our datacenter. We wrote an E-Mail to MikroTik Support on the 18th of May.

There has not been any reaction since*.

EDIT: *except for the automated reply message.

Our client has 200+ units installed in different locations, now even in 1G is not stable.
We have been pushed for months, mikrotik nothing to say.
Very bad service, client try to use Ubq to replace all CRS328.
I am thinking about it too, maybe we should close the distribution with Mikrotik.

Hi gentrice, we are angry too, but the problem we are talking here is on crs317.. what kind of problem do you have on crs328?

We are working on this problem, it could take up to a couple of weeks, to find a proper solution and test it.

Hi gentrice, we are angry too, but the problem we are talking here is on crs317.. what kind of problem do you have on crs328?
We were able to reproduce this issue on CRS328-24P-4S+ connected via SFP+ DAC to a CRS317-1G-16S+. We tested the following scenarios:

.) change SFP+ port on CRS328 -> port keeps flapping
.) change SFP+ port on CRS317 -> port keeps flapping
.) take a freshly delivered CRS317 connect it to the CRS328 -> port keeps flapping
.) take different DAC -> port keeps flapping

Turning off Auto Negotiation and pinning it on 10Gbps (tick the radiobutton under Interfaces->Ethernet) on both CRS results in a stable 1Gbps link.

The setup firmwares and Package Versions:

CRS328-24P-4S+: 6.43.12 (stable), Firmware: 6.42.5 (Factory)
CRS317-1G-16S+: 6.44.3 (stable), Firmware: 6.44.3, Factory Firmware: 6.42.11

We added this information to the ticket we have opened.

EDIT: We updated the CRS328-24P-4S+ to 6.44.3 (Firmware & Packages) -> port keeps flapping

Re: Severe port flapping on CRS328-24P-4S+ and CRS317-1G-16S+

Wed Jun 05, 2019 4:36 pm

In our scenario we needed to connect CCR1036-8G-2S+ (ROS 6.44.1) to CRS328-4C-20S-4S+ (SwitchOS 2.9) using Mikrotik SFP+ DAC 1m. We got 10G FDX connection, but it was always unstable. We had the following troubles:
  • 10G link flapping, sometimes, when it wants)
  • After a few hours of good working tagged traffic between CCR1036-8G-2S+ and CRS328-4C-20S-4S+ begun to drop. Connections begun to close one by one, until we reboot CRS. Than it works good again, but for a few hours only. After that we seen packet loss again.
  • If we tried to change any SFP+ settings like auto negotiation or set manual 1G speed, link goes down after applying and not became up. Link became up only if we reboot CRS or physically replug SFP+ DAC. And many other port settings in SwitchOS has the same bug - not working without reboot. DHCP client starts to work only after reboot too.
I think that's enough. Now we definitely completely refuse to work with mikrotik switch. It has too many unsolvable problems.
Bcause if we tell our customers that they need to wait a few weeks/months/years without Internet connection, until Mikrotik fix it, they will simply connect to another provider, and our business will go bankrupt.

Any progress on this Mikrotik? It has been 6 months with no fix. Could we have an update and a plan to a fix?

I can confirm that
there is the same problem on :
CSS326-24G-2S+ with SwOS 2.9
Any SFP+ device connected to port EXCEPT connection to CRS317-1G-16S+ with SwOS 2.7 (with any SFP+ optic module and DAC working as required)


there in not problem at all on:
CRS317-1G-16S+ with SwOS 2.7 (we are unable to upgrade to 2.8 or 2.9 because switch stops to work after 10-15 mins, but you can find this on forum as well)
many switches with many different modules and vendors SFP+s, DACs, S+RJ10

Today we started to request the replacement of flapping CRS328, where we were able to systematically reproduce it, at our distributor.

Hello. I need to buy two 24 port switches and I have to choose between CRS326 and second hand Cisco 2960G, the price is the same. If I take CRS326 it will be used with RouterOS for access switch. From what I read in forum, SwOS is not ready for "in production" setups and this is the reason to choose CRS326 instead of CSS326.

My question is - if I use only 100Mbps and 1000Mbps (random mix of ports, PCs, VoIP phones etc.) connections and not 10G connections, the problem with port flapping will be present or not?

According to all posters here, the problem presents itself only in connection with CRS317 and 10G SFP+. So it will not happen to your setup.

I think the same GuJack20. Do you have CRS326 in production? If you have, what is your opinion for the switch? Somebody else do you have CRS326 in production running RouterOS?

I'm sorry if this is mistake. I posted here because CRS328 is the same as CRS326 but with PoE. If moderators want they can delete my posts.

CRS328 to HP DL380 10gbit direct connection, port flapping exists.
so this it not mikrotik-to-core or mikrotik-to-mikrotik connection issue, something wrong in hardware design, I guess.
