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

RouterOS General

Hi, I have a problem with CRS354-48P-4S + 2Q +. The ports work from ether1 to ether8 but no traffic passes through them. Interfaces are lit, active but no traffic

[admin@SW48P4S2Q] > interface ethernet print 
Flags: X - disabled, R - running, S - slave 
 #    NAME              MTU MAC-ADDRESS       ARP             SWITCH

 9 RS ether10          1500 C4:AD:34:BD:45:D5 enabled         switch1

What I noticed is that there are no 1 to 8 ports in the switch.

[admin@SW48P4S2Q] > interface ethernet switch host print where ports=ether1
Flags: D - dynamic, I - invalid 
 #   SWITCH         MAC-ADDRESS       PORTS         TIMEOUT DROP MIRROR VLAN-ID

And if I look for port 9 it finds it.

Here is a related problem with CRS354, you can check the solution http://forum.mikrotik.com/t/crs354-not-full-gigabit-on-ethernet-ports/137954/7 and let us know if it fixes your problem…

My problem is not that my traffic is low, my problem is that there is no traffic and the ports are behaving as if everything is fine - they are recognized.

4

I don’t think it would harm your device trying the update.
Ports 1-8 is the first Group of ports and since those specific ports do not work maybe you have made any changes in the Switch menu or anything ?

This is my simple configuration, I bought the device yesterday, I’m sure the ports worked yesterday. I don’t want to return it to the dealer without being sure the reason is not in me!

I can’t take a look at your config right now…
Since it is new, in case you have no important config on it, just reset it to its default settings…
Or make a backup and then reset…
After that, remove all cables from every ethernet port and test them one by one …

I have run into a similar issue on my device. What i have noticed and am waiting feedback from support for is a simple supported vlan filtering configuration. I assign the first few ports (ether1-6) to vlan=10 and within a few hours or a day, but the vlan is un-reachable randomly. If i reboot the switch it will resume working for some amount of time. The vlan does continue to trunk and work on the sfp+ and qsfp+ ports during the un-reach-ability.

I also have noticed some 100 and gigabit enabled devices flapping port speed and link without cause (ether1-16).

I am waiting for support feedback.

8

I think we have the same problem, after reboot the traffic is run, but how long will it work ?

9

My traffic works for 1 minute or sometimes 3-4 days. I have been working on two support cases on the vlan traffic and the flapping port speed/link issue. Separately, i have added a fourth fan to the CPU cooler than 68C more like 48-56C. As a side note, that has not changes the operation, but seems more reasonable for device health. i have used a Noctua 40mm fan with the rubber grommets to secure it to the CPU heat sink.

In case it helps i will post my config in a bit.

I have the exact same problem any feedback from support on this ?

I have the same problem. I’ve just fallen in love with Mikrotik and the first device I installed at a customer is a CRS354-48P-4S+2Q+.
Configuration is only a simple bridge over all ports with activated vlan filtering and 4 VLANs.
Everything seemed to work fine. Port 1 is our uplink port to the router.
Yesterday randomly the network stopped to work. First we thought the firewall was the problem because we could still ping the servers on SFP+1 - SFP+3.
After some investigation we saw that it was a problem of the ether ports on the Mikrotik. Like OP the ether ports just showed up as normal but absolutely not a single packet was passing through.

I need a solution for this, really quick. It’s one important customer for me. I installed this switch because I only heard good things about Mikrotik.
But this experience is very bad for me. Please help!

Edit: We could validate this problem is also for us only on port 1-8. All other ports seem to be intact.

13

Did you update RouterOS to the final release 6.46.6 ?

14

Yeah when I installed the switch I updated it to the latest stable.
I just updated to 6.47beta60 in hope that this changes something.

Edit: I just saw that I could update firmware separately? System → RouterBOARD.
Does this also have something to do with system stability? It says current firmware / factory firmware version is 6.46.1

Whats the difference between the firmware and the normal RouterOS?

Edit2: Problem still there with 6.47beta60. Haven’t updated the router board firmware yet.

15

We have the same issue at a customer location. Port 1-8 is just stopping traffic forwarding. Also opened a support ticket, hope mtik will have a solution for this since its in the middle of a larger hardware-renewal at that customer, now stopped because of this issue. :cry:

16

I told my distributor about this problem with reference to this thread here.
He forwarded this problem to his Mikrotik contact person on Monday.

I ordered another 4 of this model for a complete network redesign at a customer.
I just hope this is a software problem that gets fixed quick…

If this is a hardware problem with the first switch chip, then I will get into big trouble, because my distributor said that inplace exchanges are not possible…
This would mean I have to buy multiple replacement switches, otherwise the complete network at my customer would be offline…

I hope Mikrotik will respond to this problem… this switch is cheap for the capabilities it has, but for broken hardware its too much…

17

My distributor got a response by Mikrotik:

We are aware of these complaints about Ethernet port group problem on CRS354 switches and actively investigate it.
Although the solution have not been found yet, we plan to provide it soon.

18

Is this problem present only on the PoE version?

19

same issue on non-poe version

20

Has anyone confirmed if cooling the device more helps and/or if the fans are installed the wrong way and/or the CPU heat sink is poorly mounted? just wondering if software vs hardware fix is needed. never opened up the chassis, but maybe part of the controllers for ports 1-8 are close to the CPU and affected by heat?
