Try mention above on 317:
Boot RouterOS on it, upgrade it to latest version. upgrade system firmware too. Boot SwOS and upgrade it to latest version. Remove TX/RX flow control on all switches.
Cheers

What about if you have more than two or tree full table BGP peers ? For example : > ip route print count-only 5127833 > ipv6 route print count-only 338525 Quagga based linux server can manage route changes real time without any problem. CCR1036-8G-2S+ needs 1/2 hour to process changes at just one pe...

Switch to SwOS Use it with no flapping ok, you can also buy another vendor switch, but I don't think that it was the question... Hey Mikrotik guys, where are you? Very funny - for you MikroTik = RouterOS ??!? Guy ask for solution, I gave to him one - it's not universal, but if he need basic switch ...

Upgrade to RouterOS to last version
Update firmware to last version System->Routerboard->Upgrade
Reboot
Switch to SwOS
Upgrade to last version
Use it with no flapping

I just answered on those that ask "did you manage to resolve this problem".
Everybody, of course, has own needs and requirements on same hardware - MikroTik must work hard to fix this.
p.s. forums like this one is the place to be, before buy some equipment.

cheers

I posted several times above: This problem persists only on CRS317 running RouterOS (any version). If you don’t want port flapping at all, use SwOS 2.7 or 2.10 (don’t even try 2.8, 2.9). We have many 317 in different configurations with heavy traffic, hundreds of vlans, many of them connected with 1...

We using FS.COM SFP+ modules (single-mode, single-mode BiDi and multi-mode), without any problem at all, on many CRS317, 326, 328, RB4011, CCR1009,

The question is when 2.10 will come on public, to check what they did for last 10 months?

It's very normal to have issues on copper port, because of potential difference generated by two sides of the cable. On twisted pair technology this must be no problem at all, but very often it is indeed. On the other hand optic ports have no such problem at all and power related problems are just f...

If the problem is on power supply there will be port flapping always, no matter what OS is running. I have always port flapping when winning RouterOS (every single version on it) and never when running SwOS 2.7. We have a lot of 317 some connected to 326, 328 - different versions, all with SFP+ 10G ...

You must read more above:
only SwOS 2.7 working like a charm

kosyot

There are lot known bugs on SwOS 2.8 and 2.9, especially for CRS317, and we waiting more than 8 months MikroTik fo fix it.... Keep your switch to SwOS 2.7 to avoid problems.
Check there is a lot of topics about this.

kosyot

Mr.Deslok did not mention what software running on the switch - RouterOS or SwOS. We using a lot of ..317.. and we have no problem like described above. Without issue we have bandwidth no less 9,7Gbps on both directions simultaneously on every port. Lot of our devices have overall traffic over 250Gb...

kosyot

Just use (mention above) SwOS 2.7 - 2.9 has a lot of bugs (see topic viewtopic.php?f=21&t=144031)
p.s. never use management port for traffic on switch

kosyot

Let's add some advice:

use CRS317 with SwOS (no other ver than 3.7) instead of RouterOS

kosyot

Hahaha
Not well done MikroTik - hardware related problem?
And why when you switch to SwOS there is no such problem, only CRS3017 with RouterOS?
Same hardware - different behavior = simply software bug!

1. Optical modules now it’s very affordable https://www.fs.com/products/11552.html 2. More stable and without any limitations (for example 1500 MTU on S+RJ10 and other) 3. On my opinion S+RJ10 has a lot other problems - overheating, length and type of cable, cooper connector on front and etc. We use...

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 u...

Hello, SwitchOS is one big pile of shit with no real featues, as it was intended for the general audience. When i add SFP media converters or non-mikrotik or unmanaged switches on the other end it does not pick the link up. But ROS does, hence we cannot use SWOS at all (As a last resort even if it ...

Just passing to say that MiktoTik support suggested same procedure ( boot RouterOS upgrade to 6.44, routerboard too, back to SwOS 2.9 ) for freezing problem CRS317-1G-16S+RM. Not working at all, back to latest stable SwOS for CRS317 -2.7. I see above for CRS328 is OK, seems different problem for CRS...

That means - we have that problem when traffic passes between interfaces with different speed. Most of people, I think, byes those models to extend 10G networks to old 1G equipment and it's not work...
I receive overruns on 10G eth (up-link) only.

if you thing this is normal - errors tab :

Same here!
Lot of tx/rx overruns on 10G port (SFP+ to CRS317) or pauses when flow control is enabled.
I'll wait till next SWoS release and if it is not fixed will throw away and will declare it as another cheap junk.

SwOS v2.9 has few changes which require updated fan controller firmware that comes only within RouterOS. Please upgrade the CRS3xx to RouterOS v6.44beta61, the fan firmware will upgrade along with it. Then you will be able to use SwOS v2.9 and can downgrade RouterOS if necessary as well. Tested: bo...

We using some CRS317, all with SwOS, but in diferent confugurations. Last stable SwOS release for this switch is 2.7 !! Revert to it and you will have no problem. Check the topic for SwOS 2.9 and you will see that NO ONE can use it on CRS317 - all LEDs -> turned on, no web management, serial -> work...

Upgraded two CSS326 from 2.7 and it worked fine. Still having RX overruns.

I can confirm that CSS326 working fine with 2.9 and there is still RX overruns.
Have no problem with CSS106 too, can't say same for CRS317....

I have hundreds of CapMans managing they own wireless interfaces. 1st. and very important - never use any default configuration on router - start with absolute empty configuration. 2.

Any with CRS317 & 2.9 ?

kosyot

Hi all,
Is there prove of bugs fixing appeared @2.8 for CRS317-1G-16S+ ?
Especial freezing of switch, which forced us all to downgrade to 2.7?

kosyot

Somebody tried SwOS 2.9 on CRS317 ? I'm afraid to upgrade on production systems, before there is no prove of fixed bugs @2.8.
