Re: CRS354-48P-4S+2Q+ traffic problem on ports 1 to 8

Mon Jul 19, 2021 10:04 am

Any updates to this issue, is it better with SWOS ?

It is really quiet here !?

This week i installed on my 3 CRS354 the SWOS 2.13 in the office I had no problems at all, so I will begin on Monday to replace one of my 3 HP Procurve at production site with a CRS354.
If there will be no problem after 2 weeks I will replace another one and so on.

My configuration will have no VLAN, I bouht this Switches because of the 2 Power-Supplies and the SFP+ 10Gbit.

I will report here, how it works with SWOS.

Re: CRS354-48P-4S+2Q+ traffic problem on ports 1 to 8

Mon Jul 26, 2021 7:12 pm

This thread was a disappointing find as I just purchased 2x of these.

I just put them in a rack and started configuring last friday, then found this thread.

I usually only run Long-term release so how long is it going to take before Testing-release changes show up?

If they even fix the issues anyways?

Here are some highlights from the latest Testing-release (6.49beta54 - July 5th, 2021): https://mikrotik.com/download/changelog ... lease-tree

*) crs3xx - fixed jumbo frame forwarding for CRS354 devices (introduced in v6.49beta36);
*) crs3xx - correctly filter packets by L2MTU on 1Gbps Ethernet interfaces for CRS354 devices;
*) crs3xx - fixed packet forwarding on 1Gbps Ethernet interfaces for CRS354 devices (introduced in v6.49beta44);
*) crs3xx - improved QSFP+ linking and mode changing for CRS326-24S+2Q+ and CRS354 devices;
*) crs3xx - improved switch resource allocation for CRS317, CRS309, CRS312, CRS326-24S+2Q+ and CRS354 devices;
*) poe - fixed PoE out functionality on CRS354 (introduced in v6.49beta22);
*) sfp - improved link stability for 10G, 25G and 40G modules on CRS309, CRS312, CRS326-24S+2Q+ CRS354 and CCR2004 devices;

It seems like we're not even past the re-introduce new problems phase :/

Why would anyone expect issues to be improved or fixed if big ticket items are still being fixed or were re-introduced anyways?

I <3 router OS and I've been waiting to get these for as long as i can remember, but now i'm wondering to what extent i'll use them at all. I can't physically babysit 48p switches.

Got this issue at ports 41-48 on 49beta54 firmware and 48G (non PoE switch). Outdoor security cameras on these ports went down. I thought the issue happened to 12V line or something like that but nothing helped until switch been rebooted few hours later. I guess it might be somehow related to big rain with thunder that night. Joints are sealed but nothing perfect in this world. Anyway whole block of ports went down and back after reboot. Sad story.

If you don’t need Router functionality you could switch to SWOS, I have now 3 devices running since 30th of July without problems.

Issue still persists in 6.48.4, ports 17-23 got stuck.

I noticed that there is something that may be related to this in latest rc2 of 6.49:

*) crs3xx - fixed bridge controller and extender packet forwarding for CRS312, CRS326-24S+2Q+ and CRS354 devices

Does anyone have any information if this really fixes the issue?

Watching this thread for months to see someone from Mikrotik appear to give more information about that. No one word. A little strange.

Well shit, I was about to build my new network with these switches at the core. The lack of response and root cause from Mikrotik sounds like they aren't able to fix this, I guess the Marvel chip is broken and they are trying software workarounds to no avail.

Is there anyone at Mikrotik willing to confirm that hardware revision 2 and RouterOS 6.48+ makes this switch usable?

Well, it is now removed !!! 6.49.1 and port group traffic was still blocking !

I'm really not happy in how Mikrotik dealing all this ! Not just for his product, but represent how they will deal with their other product and future product...

This is not their small entry level 15$ home router... I like having a single vendor for my equipment so there is no excuse that it because of someone else... But if they can't take care of their own gears...

I'm really disappointed since I've been rooting for them for a while and I didn't want to spend the time to find replacement gear !

Hello, still running without issue with 6.48.2 stable ?

We are considering to use the ones we have for non critical stuff (like BMC / IPMI).
Also can anyone confirm that there is no issue when using SwOS ?

Mikrotik staff maybe some official feedback ?

Mikrotik has been irresponsibly mum on this issue. The issue continues to impact the CRS354 POE switches in production especially on ports 9-16 for us.

To anyone reading who desperately wants this to be fixed because the price is so attractive - it isn't fixed, if you put this device on your network, prepare for the worst.

Why this is switch still for sale? The issues have ongoing for years and MT are either unable or willing to fix them.

My setup was reasonably straight forward - just default switching with a single VLAN on the bridge. Connections to SFP+ ports were fine, the 1Gb ports were just downtime waiting to happen on a fairly regular basis. Always had the most recent stable FW (was up to 6.48.4 before I pulled the plug on it). Functions In SwOS just fine, but you can get that level of functionality for better prices elsewhere.

Found the reason of "High CPU load" here viewtopic.php?t=179064#p936933

Still have the problem with ethernet ports:
I still see the random Ethernet ports turn off. One thing I noticed, it can happen when power went down and the switch did reboot. After that I see unstable work until I turn off the switch, wait 10 minutes and start again. Then it seems to be stable.

A job I have next week could really use a 48 Port.
EdgeSwitch ES-48-500 is still out of stock.

Distro got a bunch of CRS354-48P in.

Came back and checked this thread...

Back to looking for something else.

It's not port flapping.

You will see groups of ports stop forwarding traffic AT ALL until reboot.

This is terrible. Why is there no response from Mikrotik or acknowledgement to this problem and the switch is still for sale?
I am researching switch choices for a large network and thought I had better search the forums here before deciding.

You can use the "smaller brother 24Gig+4TenGig " ( CRS328-24P-4S+RM ) - it doesn't have this port/CPU problem.
The price is skyrocketed :O

Called back on Friday...
Customer, "That VPN hub spoke thing you did is working great. But we are having a lot of problems with local devices staying connected. We pulled the Mikrotik switches and put in some Merakis. The wired stuff stays connected now..."

I explained about this thread and my past experience.
Customer, "Well I guess that explains it."

He was pretty cool with having to swap out the switches. Must have had a return period with his distributor. Or must have actually made some money buy putting in the Meraki switches for a FLAT network.

That is a general description.
Did you actually observe this problem yourself ?
Any log check on the devices?
The previous posts mention that the switch stops forwarding traffic until reboot, but in your case there is no such description...
e.g. the client was rebooting the switches ? otherwise how was the problem resolved ? So are we talking about the same problem ?
ROS version on the switches ?

Zacharias,

I worked for them on Friday.

When I called on the NEXT FRIDAY, to ask about adding more users on Zerotier... That's when they told me they wanted me to look at the WIRELESS to explain why they were having problems.

They had already replaced one switch BEFORE they called.

They moved the Wireless to the Meraki switch and they could maintain connections.

I didn't wanna touch the switches when they were in. They had "just been installed" and I didn't want to blamed if this happened. I am pretty sure I saw 6.48 in winbox when I was working on the router.

I just wanted to post some positive feedback which is much needed during these times. :)

We have 10 units of CRS354-48P-4S+2Q+ running flawlessly.
Running stable 6.49.6
Features used: multiple VLANS, Dot1x, PoE, DHCP snooping, STP etc.

Purchased in multiple batches, running for various time - from years to couple of months.
Factory firmware varies from 6.46.1 to 6.48.3

Only complain is the "weird" Q+ ports which acts as 4 separate ones, but that is by design.

Problem solved with ros7 ??

Can anyone confirm they are absolutely reliable when used in SWOS ??

I have to buy some PoE units, as Mikrotik fan, I wouldn't switch to Unifi or some other brand because of this , it's NOT just a price matter....

Thank you

Etcoplasmosis: I dealt with an install last month, that was unfortunate enough to have 3 354... They require daily reboots to work as basic layer 2 switches.

The 354 was flawed at release. 2+ years later it's still not fixed.

Much like the RB1200 or their client serving wifi... There is stuff Mikrotik can not fix. Move on.

@gotsprings what is the revision version under /system routerboard ?
I did update the switches to whatever was current that day. Ergo routerOS and board firmware.

As for watching it...
I had seen it at home years ago. You will see a bunch of ports that just seem to be at idle. I could send a ping through those ports... So it would appear as if it was working. But nothing bigger than a ping seemed to go.

Power cycling the switch would return normal operation for a few hours or days.

Now if you look in another recent thread... A guy took over a hotel and the switches are doing this exactly.

I followed up with the guys I worked for and they had already pulled the switches. "If we had asked you first we never would have put them in."

Problems vanished when the switches did.

Revision is not the same as firmware version.
The revision i think changes when there is a hardware change on the device.

For example, my CRS354 indicates as Revision : r2.

My mistake.

I didn't notice if Mikrotik changed the actual hardware without admitting the fault or RMAing ALL THE BAD ONES THEY PUT OUT THERE FOR YEARS.

I thought you meant did I update the board firmware.

I didn't notice if there was a revision at the time.

The switches were decommissioned, (ripped out of rack and maybe thrown away) so I can't check now.

Re: CRS354-48P-4S+2Q+ traffic problem on ports 1 to 8

Fri Sep 30, 2022 3:44 am

I am having a similar problem. I don't know if it is certain ports.
The ports are switched and the moment the device boots traffic goes through. After a while, I think if I also transfer something like 100mbit data for a few seconds it stops working. No data is going through some ports.
I tried it several times and all of the times it was doing it.
At first I thought I was doing something wrong at my gateway (ccr2116-12g-4s+) breaking my b@!!S but it seems that it was because of the CRS354.
I had 7.5 and 7.6beta8 on the switch.
Btw all the devices are brand new and I am still preparing the setup for the customer before the installation takes place.

For now it looks solved by moving to SwOS but I would rather have RouterOS running.

Any help would be appreciated since the installation date is in 2 weeks

I have an install with a 328 and 326 linked with the SFP+ DAC.

Gives me 24 POE Gigabit Copper ports. 24 non POE Gigabit Copper ports and 4SFP+ ports.

I had not seen the problem in the ARM based switches after running it on my bench for a few months.

So no OS issue (swos or ros) ??
Definitely an hardware issue ?

I think the problem on mine is on ports eth9-eth16. The moment it boots they work and after a while possible when some data pass through they stop communicating. POE is working on those ports, the data are not passing

It is brand new not delivered to the customer yet. At first I was breaking my head spending hours trying to spot what I was doing wrong in my config. Then I looked it up and found that post with pretty similar problem. I also turned it to SwOS and nothing changed. You only see traffic going out and nothing coming back. If you disable and enable the port it is not coming back. The moment I reboot the switch it starts working again communicating for a while and then the problem returns. If I had read that post before I buy it I would still buy it and I wouldn't believe that it wouldn't be fixed by now.

Still no update? The situation with these switches is incredible...

I have one that worked without issues for 9 months. After it stopped passing traffic twice in the same day I replaced it... and I don't trust using it anymore.

And now I'm looking for 48 port switches at other suppliers.

Is this problem still existent, even with SwitchOS?
We are on the process of buying 02 48-port PoE switches with 10GB uplinks and CRS354-48P-4S+2Q+RM is one of the candidates but this bug is a showstopper.

Is there a way to identify the problem when ports stop working? To create a script that would reboot the switchin that case. MikroTik has become completely unprofessional in their business, and I don't understand why the EU doesn't do something and ban them from selling faulty products in the EU territory. They know about this issue and know that the devices they sell are technically faulty, yet they continue to be sold. This is against all laws and regulations.
I bought 5 of these switches and all 5 are faulty. I filed a complaint and received 5 new ones that are also defective.

Sadly... Pings still pass when the port is "locked up". This makes it harder to figure out.

But the new netwatch can query for a webpage. Maybe that would be enough to let netwatch know it's down. Then you could REBOOT THE WHOLE SWITCH.

(That's right... That's what has to be done when ports stop passing traffic.)

Was talking with another company's tech. He needed a EdgeSwitch to complete an install that required passive 24Volt and standard AF/AT power at the same switch.

Since he had been waiting for the EdgeSwitch for over a year at this point... I pointed him to the CRS328-24P I have settled on. I specifically stated that I use a DAC cable between multiple switches to increase port count.

I also specifically pointed him to this thread.

What did he do? Ordered a CRS354-48P. (From a US distributor who doesn't take returns...)

"I couldn't find that post you were talking about."

I have had 2 of these switches running live with no issues for over 6 months running RouterOS v6.49.6. The load on these is not large and only 4 or 5 ports are really being used on them at a time. I recently started swapping out some rack switches with these switches before I ran across this thread and what a mistake that has been so far. The first one I swapped in lasted for 33 days before port flapping for a few hours and then halting all traffic altogether when no was in the office. The other one did the same thing within 4 hours of going live, all ports just stopped passing traffic except for the management port. These new ones I swapped in were both running RouterOS v7.8 (stable) These are very basic setups with no VLAN's. Hard to believe they have not recalled this product at this point.

Re: CRS354-48P-4S+2Q+ traffic problem on ports 1 to 8

Thu Jun 15, 2023 9:28 pm

Been having this issue across our stores. We have 100+ of these switches installed and ports 9-16 are basically unusable. We have put it on our "do not use" list and are using 2 of the CRS328-24P-4S+RM in place of 1 of the 48P switches.

Sad. But in our last order of these switches I noticed that it now says "r3" for revision 3. All our previous switches were either r1 or r2 (mostly r2) so I wonder what is new with this r3 version?

Regarding revision 3 of this switch, this is what support said:

"Revision 3 comes with larger flash storage - 32MB."

So I'm sure it's not fixed if that's the only thing that has changed on it.

They are still selling that switch as if it's perfectly fine, without any shame. This needs to be reported to regulators, other companies have paid large fines, in millions and billions for such behavior in the EU market. What they are doing is a criminal offense.

I would buy immediately 354 (poe or not) but this issue made me buy Aruba or Ubiquiti units without take the risk of try one.
It's still not clear how many 354 have been sold and how many have the issue , how many get issue running ros and how many swos.
I can't believe Mikrotik doesn't know about.
They offer great products @ great cost and almost 100% support and issues-solving.

So what happened with your switch purchase?

The only site I have with 354s in it are asking for a replacement.

I mean... I did ask.

And yes they want the switches replaced due to the reboots required to make the switches pass packets again.

They are still not in stock. I've tried searching at all major suppliers in Denmark, strange... Our main supplier can't tell anything about delivery date, because the import company don't have a date... I wonder if it's related with the issues, or it's just shortages.

No need to by from a distributor having them from an importer, both putting their own margin on top of the price for doing nothing else then forwarding your order.

Yes, the POE version is also available in Denmark, but for Edge switching / AP's we are into the Unifi ecosystem at the moment, so we don't need POE. CRS354's QSFP+ and SFP+ ports combined with the RJ45 ports, matches exactly what we need for our 2x "Server / Distribution" switches in our setup.

Is anybody familiar with the HPE FlexFabric 5900AF 48G 4XG 2QSFP+ ? The specs looks very much the same but I've not worked with HP switches before...

Edit: Ok, that HPE 5900AF is rather old... Is anybody aware of an alternative with minimum 2x QSF+, 2x SFP+ and 24x RJ45 ports, alternative minimum 6x SFP+ and 24x RJ45 ports ?

Since there are 2 threads out there about people having just bought this switch and are having issues...

Time to bump this thread to the top again.

Maybe they will release a new model instead of fixing the old one ;-)

Thanks for the link, and I cancelled the order on the CRS354 I had ordered. Then I hope the old switches they should replace, will hold a little longer...

We unfurtuantely have the same issue, but our CRS354-48P-4S+2Q+ ran fine for many month until about christmas 2023. Probably because we use it with SwOS from the beginning it took longer for the problem to occure. Now as we received strange network issues with failing ports 1-8, I found this thread and took about two hours to read through the previous years. Problem is that there is not a newer SwOS version than 2.13.

The problem seems to be not fixed yet, after nearly four years and I doubt it will get fixed in the future.

Have you guys tried 7.13.1? Those switch changes should fix the CRS354 issues described in the topic

@normis.

Welcome to the thread.
(3 years 8 months and 13 days)

Hopefully we can finally get these units working, and we can take them off the "do not quote list".

Re: CRS354-48P-4S+2Q+ traffic problem on ports 1 to 8

Sat Jan 20, 2024 6:48 pm

I cannot reproduce this, It is happening randomly really.
Sometime this unit work for couple of months, sometime 2 days.

Unit is always reachable with ping, winbox or even ssh. No problem. Just clients connected to eth ports become offline. Still have LINK but no data are transfered.

Yesterday I bought new crs354 r3 unit and replace it. So now I am curious if will help or will this new revision on new unit will do the same sh*t.

BTW. for testing purposes I was not using first 8 port for couple months, it did not help, problem was still the same

Re: CRS354-48P-4S+2Q+ traffic problem on ports 1 to 8

Wed Jan 24, 2024 2:35 pm

For my part I have 4x48P units at a customer site that have not exhibited this problem that we know which have been up well over 1y at this point, but also 3 of the 4 are really sparsely populated, so if there was a block of 8 stopped ports on a switch it is not impossible it is simply a block of 8 which are not in use and so it's not been noticed. They're pretty minimal config, no LAGs, at most 4 vlans, and all just uplink to a RB4011, so they're about as basic as it gets.

The only reason I am here is because I was about to buy 2x48G that would see much more use than those existing 48P switches and I have now seen this thread.... :|

Has anyone else tried the 7.14 betas with these switches like the last poster here to see if it cures their issues? Seems a bit early for them to declare success given some people in here have said they'd had as much as a month or so with no issues on other firmware; viewtopic.php?t=202646#p1049369

After reading this topic, I was expecting similar problems, but I've been waiting for 3 years for something to stop working...

Probably users who have problems have caused the device to overheat because it is in a place with little replacement or covered by other peripherals...

It's a rack mount switch, if it can't handle being installed in a rack "covered by other peripherals" then it is defective. So glad I didn't take the gamble on this hardware, it's ridiculous that these are still being sold with so many problems.

as I posted in the thread... I was brought in on a job where they already had the switches. And they were having to reboot the switches DAILY!. As soon as they told me the model of the Switch I described exactly what was going wrong.

Client, "Is there a fix?"
Me, "You found the workaround. Reboot it and it works 'for a while'. Since pings still pass when its locked up... you could maybe set the DLI to check a webport. When that stops working reboot???"

All switches were tossed.

two of my units (I have around 15pcs totally) are affected with this issue and both are failing on ether1-8, I can confirm that, no any other port show problem...
Also may I know your topology and what kind of traffic is mostly going through your switches(unicast,multicast,broadcast etc.)?

any progress with version 7.13.4 or are there still problems?
We are thinking of buying 2 switches for the company and after reading this thread I have no confidence in CRS354.

It's a sick joke from Mikrotik guys:
https://mikrotik.com/product/crs354_48p_4s_2q_rm

CPU: QCA9531 (MIPSBE)
Switch chip model: 	98DX3257 
Size of RAM: 	64 MB
Storage size: 	16 MB 

https://mikrotik.com/product/crs328_24p_4s_rm

CPU:  	98DX3236 (ARM 32bit)
Switch chip model: 	98DX3236 
Size of RAM: 	512 MB
Storage size: 	16 MB

The CRS328 is far superior hardware.

We have heard prior firmwares corrected this.
