CCR2216-1G-12XS-2XQ + CRS312-4C+8XG-RM with gigabit connections is way off in speed

Sat Feb 04, 2023 11:23 pm

CCR2216-1G-12XS-2XQ + ( XS+DA0001 or SFP+ 10G ) + CRS312-4C+8XG-RM with a S+RJ10 plugged into any 1 gigabit device produces no more then 700 Mbps.

CRS312-4C+8XG-RM is running switchOS

All firmware is current stable.

Turned on flow control on the router port. No difference. The router shows tons of RX Pause frames.

WHat am I missing..

So a 10G router > 10G switch > 1 G device = 700 Mbps...

But doing a CCR2216-1G-12XS-2XQ + ( XS+DA0001 or SFP+ 10G ) + CRS326-24G-2S+ = 990mbps

So 10G router > 1 G switch > 1G devices = 990mbps

Is the 10G switch or the 10G router not doing flow control correctly ? Or, whew, Im confuzed.

Separately, but maybe related..

Putting a S+RJ10 into the CCR2216-1G-12XS-2XQ and hooking up 1G devices produces 700 mbps, UNTIL, you uncheck auto negotiation and then turn it on again, then its 990.

I tried doing this trick with the 10G switch, but, no help.

Well.. The XS+DA0001 does not auto negotiate. You must do manual at 10G.

I tried for 5 hours on the phone and had people rearrange things as I was remote connected. I cannot find a way to get any more then 700Mbps out of the 10G + 10G + 1G device.

I guess separately, should i run RouterOS in switches and just bridge all the ports ? Same performance as SwitchOS ?

I like using Winbox rather then the web interface.

Don't expect much response given what's shared so far. This 13 year old post: Getting the most out of this forum is still gold.

RouterOS supports so much more on CRS312 than SwOS including many undesirable things like Layer 3 routing and firewall when CCR2216 does those so much better. Suggestions:
  1. Visit CRS312 Test results page. Compare "Switching results" to "Ethernet test results".
  2. Visit CCR2216 Test results page. Compare "Ethernet test results" to CRS312 Test results.
  3. Carefully compare the lines with matching "Mode" and "Configuration" values for accurate and valid comparison.
RouterOS provides more switching configuration options than SwOS; I use RouterOS on CRS309 and CRS326.

Hmmm... I shared the topology, the devices, the settings, the problem and my steps I did to isolate it. I did that in a very clear and concise manner.

Im not sure what other info is needed ?

Maybe that i have done ROuterOS for 13 years ? BUT, I could have missed something for sure.

Not sure what other info is needed ? Lets see devices, how they are connected, results, trying different things.

BUT I *DO NOT* have a lot of experience hooking a 10G Router + 10G switch to 1G devices. Maybe I should use RouterOS in the switch for some odd reason VS the current SwitchOS ?

I could draw a diagram I suppose. But its pretty simple. Above model router > Direct attach SFP+ > Above model switch > above model SFP+ multirate ethernet module > ANY 1G device.. Current OS on all. Will do it with fact reset config. This will do 700Mbps tops and throw a lot of RX Pauses in stats on the router. Its like its rcving the flow control packets but not acting on them even with flow control on on the router.

Well yes. But if you bridge all the ports on RouterOS I think it gets really close. In fact. The switch ships with RouterOS. So I was thinking that switching it over to SwitchOS might have created some issue.

And from the specs I would expect more then 700mbps from a switch.

If I plug in a 10G device in, I get nearly 10Gbps. Plug in a 1Gbps device I get 700Mbps.. So the switch can do 10Gbps in its default config. But if you plug in a 1 Gbps device you will get 700mbps and a huge number of RX Pauses. Not the 940+ you would get normally. Its like the router is somehow ignoring RX Pause packets.

@Xymox if you're not going to put work into the process to make it easier for others then why should others ...?
IMO normis wrote a good post but I'm not seeing posting improvements. Given so, I've lost interest. Good luck!

Well im sorry you feel that way. I thought i put everything needed into the post ? Im not sure what other effort I can do ? I could create a support email with supportout files, but, I wanted to see if I was doing something dumb and missed something before bothering anyone else and there are lots of seasoned pros here who are smarter then I.

The switch or the router seems to be missing the RX pauses and sending anyway ? Its like flow control is not on when it shows it is ? OR maybe I am just stupid and missing something dumb ?

I can't replicate the issue with another Tik router and switch i have. These are both new products and I thought maybe its a bug.

The weird way the router was testing out at 700Mbps and I clicked auto negotiate off then back on and it suddenly snapped to correct speeds was weird. The negotiated speeds did not change. Nothing did. But suddenly it went from 700Mbps tops to 940+ and has not dropped since even after reboots. I think I would count that as a bug ?

Full fact reset and put the switch back on RouterOS. No change in symptoms. BTest and external tests all with the same results.

CCR2216-1G-12XS-2XQ > XS+DA0001 > CRS312-4C+8XG > S+RJ10 hooked to any 1Gbps device produces 700Mbps, On the router lots of RX Pause. No TX pause.

CCR2216-1G-12XS-2XQ > XS+DA0001 > CRS312-4C+8XG > S+RJ10 hooked to any 10Gbps device produces nearly 10gbps

Flow control on or off does not seem to affect results of this test.

Different cables tested, no difference. Reset config no change.

With a 1G device plugged in, 700Mbps. Unplug it. Plug in a 10G devcie, nearly 10 Gbps. Plug back in a 1G device its back to 700. Tries lots of different devices.

Interesting. So after 5 days no one has any idea about what I am seeing ? Maybe a bug ? I am surprized by the lack of responses, I suppose all forums eventually degrade. I clearly followed the guidelines to post a issue. I will work up a support email noting a lack of response on the forum to a well defined issue and include supouts and all the normal stuff.

I will also go do well defined reviews on all the normal places for the 2 new high end products covering this issue and that there was a lack of response to it. As a Streakwave dealer I will also go talk to my rep.

I am sad that Mikrotik, and this previously very helpful forum, has devolved to a point no helpful responses occur at all.

In the reviews I am linking to this tread, so, a fix to the issue posted to this thread will address the reviews I post.

It will be tomorrow before I can set this all up again and do a supout and submit a support ticket.

After doing Mikrotik for 13 years this is my first bad experience. I dont mind bugs and oopsies. Those are no issue at all. But when support fails, thats when there is a real issue.

I wonder if it has something to do with the CCR2216.

The ports is 2x 100G and 12x 25G ports.

You can try to disable the auto neg on the ports between your router and switch and set it to 10G

I have a CCR2216 , CRS326 and a RB5009 on my table.

I can try and reproduce the issue as soon as i find the time

Not going to read all details, but you are having a server on 10G and a client of some kind on 1G at the other end?

Mikrotik switches are known to not have big packet buffers - and when you try to feed a lot of data into a smaller pipe, the packet buffer on the switch takes a hit, causing packet drops - and lowers the bandwidth.
