I just installed 2.11 on my CRS317. Hoping that it would solve the switch its reboot problem. The / my CRS317 switch does not proberly reboot after rebootcommand or powerup, see my post in 2.10 a couple of days ago.
However, that problem is still there. The switch did not properly reboot after installing 2.11 (same problem in 2.10). Disconnecting the power for a minute did solve the problem, but that is of course not ok!
οκ..
Two CSS326 10G connected back to back. We had Tx pause frames both sides when flow control is off in version 2.10.
Upgraded to 2.11. Now we have Rx pause frame increasing both sides with flow control off…
Just upgraded and we have an issue where our SFP+ connections do not work after reboot, we need to pull and replug them or disable and enable them to get them to work again. Any hints for us? We are using an CRS312-4C+8XG.
We need help with this firmware upgrade on our switch.
Did an firmware upgrade from 2.10 to 2.11 via SwOS browser page “upgrade” - same as we did it to 2.10 app. 3 weeks ago when we first got it.
Everything looked normal, but after reboot SwOS does not want to boot (fans keep spinning up&down every 5sec, all lights go on & off - are still spinning after 30mins) but the SwOS never starts.
A cable of a laptop plugged in states “Cable unpluged”.
Switch is not reachable on a static IP that was defined before /and worked) even if it is defined in RouterOS for SwOS static IP.
We can get the switch to boot into RouterOS on 192.168.88.1 if we hold “Reset” button on a switch for a couple of seconds, but would prefer SwOS as it was supposed to be a simple setup.
Config reset of a SwOS in RouterOS did not reset switch to factory default as we wanted to repeat our setup from scratch, but seems to remove only our SwOS settings.
I can not see what is current installed firmware version.
We would at least like to revert to 2.10, but none of the things we tried so far worked.
We uploaded the swos-css328p-2.10.bin to “Files” via RouterOS - but did not find a way to install it that way.
@Louis2 - unfortunately, we did not manage to repeat such reboot issues, please report this to support portal or email to support@mikrotik.com @chaigeo - the switch should not generate any pause frames when the Flow Control is disabled. We look forward to improving this on upcoming SwOS versions. @lofwyr - thank you for sharing, the SFP+ initialization after reboot seems to be failing on CRS312 device, we look forward to improving this on upcoming SwOS versions. @wwwposdev - can you connect a serial cable and see what output does the switch shows when it enters the reboot loop? To install the newest SwOS version, try to follow these steps - Cannot upgrade SwOS.
One of the last standing issues is still having pause frames between CRS328-24P-4S+ and CCS326-24G-2S+ with 3M mikrotik 10GB SFP+ DAC on the trunk SFP+ ports.
The network has 2! physical DHCP servers, one DHCP serving the untaged LAN and 2 tagged vlans from trusted port 24 on the CRS328 the other is on trusted port 24 of the CCS326 having 3 tagged vlans. However there are no tx/rx pauses nor errors on ports 24 of both switches only the trunk between them!
Interresting is that it has “double the amount of pauses” on the CCS326 as in 40 RX pauses with 20 TX pauses on the CRS328. Another mikrotik forum user @Siemer related this issue to DHCP package being dupplicated and forum user @ruffy91 seems to fix it with disabling DHCP & PPPOE snooping “Add information option” 1 around SWOS 2.4/2.5 version.
@EdPa, thanks for the instructions.
SwOS upgrade via RouterOS console worked as described - after loading the RouterOS, try to upgrade SwOS using the
/system swos upgrade
command
It seemed it did not even make any download or maybe even the installation - it was instant 1-2sec response “v 2.11”
It booted on first try and then rebooted SwOS without issues.
So we’ll continue with SwOS as planned.
We noticed there were quite a few posts about dropped packets and errors on switches using RJ45 → SFP+ ports.
We also had some warnings about dropped packets - Rx MAC Errors, Rx FCS Errors and Tx Pauses.
Our setup:
Unifi USG‑PRO‑4
Unifi US‑16‑XG
Mikrotik CRS328-24P-4S+RM (connected to US‑16‑XG via SFP+ cable & “FiberStore SFP-10GSR-85 A G1804125499”)
Errors were reported by a server (netdata warnings) and onother computer connected to Gb ports on CRS328. But errors were registred (displayed on SwOS) only on SFP+ port 2, which is connected to Unifi 16-XG. Today we changed this connection to SFP+ port 1, using same module and cable and errors were mostly gone.
Was it due to SwOS update or switch simply prefers SFP+ port 1 - I do not know.
We then connected another computer with SFP+ cable directly to CRS328 > SFP+ PORT 2 and then tried multiple iperf tests:
Client (SFP+) > US‑16‑XG > CRS328 > Server (Gb RJ45)
Client (Gb RJ45) > CRS328 > Server (Gb RJ45)
Client (SFP+) > CRS328 > Server (Gb RJ45)
Client (SFP+) > CRS328 > US‑16‑XG > Server (SFP+)
GBit transfer speeds are full, 10Gb connections vary from 3-6Gb/s (but that could be due Proxmox, Windows in a VM, other running processes etc.)
Multiple tests did not produce any errors. After 1-2h Errors page looks clean whereas before it started showing Errors as soon as there was any real-life traffic going to the switch.
Maybe it will be helpfull to admins or some of the Mikrotik users.
p.s. thank you for the quick response. We saw some users/posts waiting for months being left with no solutions and some doubts regarding our decission going with Mikrotik already started to emerge.
We did our first regular SwOS update and “the music stopped”. On a brand new, semi-flagship switch that is supposed to be the backbone of our small-biz GBit network.
This feels much better.
My hardware is CRS312.
When i use router os.The CPU Temperature is about 50-65c.Fan speed will keep about 4000 rpm.You can fell it’s quiet.
But,when i use SWOS .The CPU Temperature is about 48-60c.Fan speed will run at 6000 rpm to 8000 rpm.You can fell it’s noise.
This is unreasonable.
I want to use SWOS.Because i don’t need to use router.
But my CRS312 is working in my edit room.It affects my work.
Can fix it please.I can’t control fan speed.
You can configure your CRS to perform exactly the same functions under ROS as it does under SwOS. It will even have the same performance (if configured properly). The only difference would be the management UI.
SwOS UI is more like a switch.Such as, I can easy to look for RTSP VLAN LAG.But ROS is difficult for me to find them.I bought CRS312 just wan to use to switch.
I can’t upgrade my CSS106-1G-4P-1S (new RB260GSP) from 2.7p to 2.11.
I have bought it yesterday as brand new device.
I read /viewtopic.php?f=21&t=151881&p=752204&hilit=CSS106+1G+4P+1S#p752231 and it does not help.
Neither on-line “Download & Upgrade” nor “Manual Upgrade” (from swos-css106-2.11.bin) works.
While Manual upgrade I see message “Upgrading… (Please do not interrupt)” within 4-5 seconds and then it reboots. Version remains the same, 2.7p
On-line upgrade shows 2.11 changelog, pressing button “Download & Upgrade” also shows
“Upgrading… (Please do not interrupt)” then “Rebooting..” and nothing changes.
I reset device, repeat upgrade but it remains with version 2.7p
PS
I upgraded it to 2.11 at last.
I have “main” router RB3011 (CAPSMAN manager) and 951G-2HnD as CAPSMAN client. RB260GSP was connected to 951G-2HnD.
Upgrade was failed in such connection. But upgrade was successful when I connected RB260GSP directly to RB3011.
