Since then I have switched to an RB4011 which works fine with the iMac Pro in question. Probably an undocumented incompatibility between the AQuantia AQtion AQC107-AFW adapter and the Atheros8327 switch chip in the RB2011. Also - just a side note - this adapter works flawlessly with the S+RJ10 SFP+ ...

With default configuration how is the speed link?

Regards.

100M full-duplex. There is some data flowing in both directions (a few frames per sec) but the mac can't even get an IP from the DHCP.

ToMikaa87

Update: i've booted a Windows 10 instance on the iMac Pro using Bootcamp and it's still not working so I'd say it's not an OS or driver related problem. I've tried changing various settings on the adapter's control panel in Windows without any luck. I also tried to enable debug logging in WinBox hop...

Did you try older Mac OS? https://discussions.apple.com/thread/8508719 https://discussions.apple.com/thread/2170974 Mac problem on horizon I didn't and unfortunately can't. I work on this machine and I need the latest OS. However the posts on the forum mention a way older OS version and the origina...

Did you also update the RB firmware on the 2011 (is it in sync with the ROS version)?

Yes, it's updated to the latest as well.

ToMikaa87

Did you try setting the router port only to 1G ? Yes, and also tried to change RX/TX flow control. Also try to set 1g only on you Mac. Anyway is weird that the auto-negociation can't do it at 1G. As addition, is interesting to know if the same thing occurs with another RouterBOARD. Regards. I've tr...

You checked that the 8 pins of your cable are OK? If your cable is made on the fabric, anyway test it. Yes, of course. I've mentioned that I tried an external USB-C adapter and I used the same cable and it worked fine on Gigabit. I've used a fully wired 3 meters long CAT6 cable, it should not be a ...

Hi, I try to connect an iMac Pro (which has a 10G AQuantia AQtion AQC107-AFW Ethernet adapter) to a Gigabit port on a RB2011UAS-2HnD. The issue is that after a somewhat longer auto negotiation phase (~10 sec) the link speed is set to 100 Mbps. According to the status page of the Ethernet port, the r...

hi, I now have a serial port lcd.....how can I connect the said RB411 board to it?

Probably this answer is a bit late but this issue can be caused by the faulty Atheros 8316 switch IC which causes router freezes on RB450G/493G boards? This IC dies under heavy load and only resetting the chip or the board itself solves the problem.

ToMikaa87

Dear Community, I have an RB2011UAS-2HnD router used as my home router. Its setup contains many firewall filter and magle rules, and a queue tree setup. The router is connected to the Internet via PPPoE on e10-wan (ether10). The WAN connection speed is 44Mbit download and 22Mbit upload. There is a N...

ToMikaa87

I have tested the switch (normal usage over a few months long) and it seems fine to me. No stability or speed issues. I can easily run iperf going at a full gigabit a second for say 30 minutes without a problem. The same with copying 120GB from one port to the other using CIFS. Further on the wirel...

ToMikaa87

Hi, My question is about this board that do somebody tested the switches utilizing the maximum bandwidth? Do the new Atheros chips solve the issue present on the older models (mine is RB450G) equipped with Atheros 8316 switch IC? (Switch hangs when you send huge amount of data through the switch wit...

ToMikaa87

We are not aware of any freezing, unless you mean issues with Metarouter and these chips. If you have encountered any such issues, contact support with more info. I did it without any success. I always got the answer that the issue cannot be reproduced. I wrote my problem on many forums and that re...

ToMikaa87

In addition, many RBs that have the Atheros 8316 switch (like RB450G, RB493G etc.) suffer from ethernet interface failures under heavy load that makes these boards more unreliable. And definitely this issue cannot be fixed by software updates.

ToMikaa87

Are there any improvements about the Atheros 8316 switch IC? I mean the switch freeze issue on some gigabit RBs (RB435G, RB493G, RB450G).

ToMikaa87

Did someone try the latest 6.0beta3 ROS on an RB435G/RB450G? Is the switch chip still freezes under heavy load? The changelog indicates that there is a new kernel in that release and drivers were updated.

Edit: the issue still exists.

ToMikaa87

RB450G has the problem, too. Seems to be related to the Atheros 8316. After 2 minutes of full load (Gbit traffic between 2 ports) the switch stops working.

ToMikaa87

if you have RB450G still in place, you can try by reducing cpu speed to 400MHz that will be the same as RB7501G regarding speed.

I just measured it and at about 60 Mbps the CPU load was 100% and about the half of this usage was queuing so this CPU speed is simply not enough for such bandwidth.

ToMikaa87

we have not tested exactly that, but you can try. After all it has around 370Mbps throughput with firewall/conntrack and routing

swtich is wirespeed.

And how much is the speed drop if I use queue trees (+many firewall mangle rules) for QoS purposes?

ToMikaa87

what about RB751G, however it has integrated radio. I saw that and it looks much weaker than RB450G (slower CPU, slower switch throughput) and I'm not sure if it can handle my 80 Mbps PPPoE WAN connection. In addition I have a few PCs connected with Gbit that put large amount of data through the ne...

Hi, Recently I was looking for a replacement of my broken RB450G and trying to find a solution that has enough gigabit ethernet ports and a miniPCI slot for a WiFi add-on card. I found the RB493G which is a little bit expensive and the 9 ethernet ports are too much for a small network (like mine). I...

ToMikaa87

I tried to make a configuration based on your solution using a pfifo and a different method for packet marking and it seems to be working. I had to adjust the pfifo size to 10000 to let the router handle a larger traffic.

ToMikaa87

@Oldman: i have tried your solution but it's still not working as expected. When p2p is running at maximum speed, HTTP download is very slow. I can see the correct speed values in the queue tree so packet marking is OK.

In my opinion there is no need to worry about wearing out the flash. On most RouterBoards the RouterOS is stored in the on-board NAND flash and working without a problem.

ToMikaa87

Still no updates and no response from support for me.

Edit: I just got an answer from the support:

Hello,

Sorry for the late response. The problem is found and we are working to fix it.

I found another symptom. If I create an SMB share in the root of the microSD and copy files to it, these files are not deleted after rebooting the router, but if I create a sub-folder it is deleted after a reboot including all its contents. So probably there is a problem with folder handling. The si...

And I made supout.rif files.

ToMikaa87

5.2 still has the througput issue.

ToMikaa87

Please upgrade to v5.2 and test again. It contains fix for supout.rif generation as well.

I can confirm that supout generation and console is working again. Bug report was sent with the support file.

ToMikaa87

And what about the very low bridging and switching speed issue? Will it be fixed soon? What are the steps to reproduce this problem? Please send this report along with supout.rif file to support@mikrotik.com. I cannot create a supout.rif because console process hangs during creation. I think it's r...

ToMikaa87

The problem with console consuming all the CPU resources will be fixed in v5.2.

And what about the very low bridging and switching speed issue? Will it be fixed soon?

ToMikaa87

I can reproduce this issue too. This is the console 100% CPU usage issue too. In such case you can still log in using WinBox and manage router from there. (reboot) 5.1 on a 750G Connect via ssh/telnet and type "interface ethernet switch ?" and ALL(!) ssh/telnet sessions will freeze instan...
