RB5009 and S-RJ01 SFP speed problem

Sun Oct 03, 2021 12:34 am

Hi guys,

What could be issue with RB5009 SFP auto neg only 100Mbps ?
Old router was 1Gbps with the same cable.

Auto Negotiation: incomplete
Rate: 100Mbps

Vendor Name: Mikrotik
Vendor Part Number: S-RJ01
Vendor Revision: 1.0
Vendor Serial: 61B103C43CC5
Manufacturing Date: 20-02-24

running 7.1rc4

Thanks,
Artis

Hi, with my S+85DLC03D also have problem.

With MM cable, connected to CRS318-16P-2S+ i have still link downs, sometimes a few, sometimes hundreds for a day.

Ros 7.1 rc4

I had the same issue with an S-RJ01 SFP in a RB4011 running 7.1rc4 and a cable/port working stable with all other tested devices.
Sometimes it connects at 1GB with autoneg enabled, when the SFP port is disabled and reenabled some seconds later using Winbox or terminal.

What helped to get a stable 1GB connection was to disable autonegotiation in SFP port Ethernet settings and force it to 1GB full duplex.

In our experience, the S-RJ01 tends to have autoneg/flap problems in MikroTik devices. We have much better experiences with Copper SFPs from fs.com and Starlink, working without issues in all our MT devices.

Connector type is reported as LC, should it be rj45 ?

It is a "LC to RJ45 converter".

In my case I get tons and tons of TX/RX packet errors. I can't use them.

Have Mikrotik commented on those ? Could not find much on the web.
I also opened support case.
Looks like hit and miss and much more miss than hit.

Wonder if S-RJ10 has the same issues ?

Hmm, so I connected SFP to cheap dlink gig switch then other switch port to ONT and SFP was running at 1Gps for 30min or so with no issues

This is SFP directly to ONT:
sfp to ont - link.png
sfp to ont - speedtest.png


This is SFP connected through switch to ONT:
sfp through switch to ont - link.png
sfp through switch to ont - speedtest.png


Link auto neg is still incomplete though

We have seen CRS, RB4011 and RB5009 devices having auto neg issues with fibre and copper 1G SFP modules running in 10G SFP+ ports. Auto neg status never completes, depending on the device at the other end resulting link is reported as none, 100MB or 1GB and is prone to flaps. Connections to media converters and ONTs tend to be more problematic than those to switch ports.

As mentioned above, it's worth trying to disable auto neg and forcing 1G FD on sfp-sfpplus1. Helped for us more than once.

I've been surprised by a S+RJ10 module still displaying a 10Gb/s rate though being configured (on both link ends) to work at 1Gb/s (see another thread opened yesterday). This was between a CCR2004 and a NetPower 16P (both with 6.48.4).

Maybe:
- rate displaying is not perfect
- auto neg settings are misleading (ie do not do what many people expect they would)
- there is some bug somewhere.

Yes, I have connected directly 2 RouterBOARDs.
I not know if S-RJ10 have functionality issues, until now I not found any topic about it, but it has very serious temperature problems (~90°C).

Got some 10 years old PlusOptic 1G SFP and 2 x FlexOptix programmed for Mikrotik, Juniper

All of them did not work with auto negotiation.

I disabled auto neg and they all worked at 1G speed.

When I changed the speed to 100M, they still reported 1G speed.

Re: RB5009 and S-RJ01 SFP speed problem

Sat Oct 09, 2021 2:04 am

Many 1G SFPs contain a Ethernet Copper/Optical PHY chip talking SGMII to the SFP host. The autoneg is handled by the PHY, not the SFP host.
The physical bitrate for SGMII is always 1GB, for 100MB every byte is repeated 10x, for 10MB 100x.

Looks like the reported bitrate is the physical SGMII rate between the SFP host and the PHY. Not the actual wire speed the PHY has autonegioated.
It also looks like the SFP+ port bitrate has to be forced to 1GB to match the physical SGMII bitrate.

I have an RB5009 as well. If you haven't solved yet, the setting is under 'Interfaces' tab. Then select 'Interface' tab at the top left. Double click the interface you want to adjust. At the top of that window, select 'Ethernet'. From there you can play with the settings.
