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

Fri Jul 09, 2021 4:09 pm

We need help: we are planning to replace all routers with CRS354-48G-4S+2Q+RM, but in the light of the problem described in this topic, there are big doubts.
1) Tell us what happened in the end: everything is fixed and working, or is the problem still there?
2) Is it worth buying a CRS354-48P-4S+2Q+RM or is it a problematic device?
3) I also heard about the problem of packet loss (traffic) - is this the same as in this topic or is it a different problem?
4) What is the best firmware version for this device now?

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.

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.

FYI we've had this problem on ports 9-16 for some time and had it on 6.48.1 a few weeks back. Then we tried upgrading to 6.48.3 (the current release) and within an hour and a half of being on the new RouterBoard + OS the same problem happened on ports 9-16. So from our perspective it has not been fixed in 6.48.3. Mikrotik said to try an RMA versus expecting a software and/or firmware solution. We may do that if we continue to see problems on 6.48.3 and see if the later silicon or later manufactured units aren't as iffy.
I have had my Piece of S--t too long. So I can't RMA it.

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.
