8200/6100 Intel x553 NIC and certain SFP+ modules

[aholmes5]

@stephenw10 Lots of In errors. No out errors and no collisions.

[stephenw10]

Interesting. Then check the stats in the sysctl to see what sort of errors they are: sysctl dev.ix.0

The C3K NICs are limited in the information they can get from modules about the link state. That can mean they negotiate incorrectly or fail to link with some media types. XPON modules that that hide the real link and present to the NIC as something else so there are a few things there that could cause problems.

@stephenw10 SFP in 8200.txt SFP in switch.txt

Here is what I have. I don't know how to interpret this. Lots of errors:
dev.ix.0.mac_stats.rec_len_errs: 20
dev.ix.0.mac_stats.remote_faults: 0
dev.ix.0.mac_stats.local_faults: 53
dev.ix.0.mac_stats.short_discards: 7
dev.ix.0.mac_stats.byte_errs: 1425
dev.ix.0.mac_stats.ill_errs: 873
dev.ix.0.mac_stats.crc_errs: 5468
dev.ix.0.mac_stats.rx_errs: 6374

[stephenw10]

Mmm, interesting no one type....

Check netstat -m make sure there's no buffer exhaustion happening.

Hi @aholmes5

I have the same issue. I connect my Fiber WAN on SFP+ 10G on netgate 6100 with a 10GTEK sfp+10G and my unifi switch on the second WAN on SFP+ 10G on netgate 6100 with DAC 10G cable but my download speed is reduce of 80% but my upload is fine.
Do you found a solution ?

[stephenw10]

Are you seeing errors on the interfaces?

Do you have any traffic shaping?

[lio1503]

@stephenw10
I see some error on interfaces and no traffic shaping configured.

[lio1503]

[stephenw10]

No errors shown there. So some on the WAN?

How are you testing the throughput?

[lio1503]

@stephenw10

I put the wrong image sorry

[stephenw10]

Hmm, not really a significant number there. Nothing that would cause throttling to that extent.

What about the PPPoE parent interface? Which I assume is ix0?
Try: netstat -i and ifconfig -v ix0

[lio1503]

Hi @stephenw10

Here the result of commands

Thanks

[stephenw10]

Ok huge number of input errors on ix0. That's what you'd expect for bad downloads.

You have an XPON module in there I assume? Can you access that to get stats?

You can check the sysctl output for ix0 to see what type of errors those are: sysctl dev.ix.0

[lio1503]

@stephenw10

Yes I use this module on ix0 https://www.amazon.ca/dp/B06XG9DPJ7?th=1
and this cable to unifi switch for Lan on ix1 https://www.amazon.ca/dp/B01M09C9NZ?th=1

However what's different is that that isn't an XPON module it's just an 10GbaseT module.

Technically neither type is supported by the X553 NICs because they don't have the data lines to detect the link type.

What exactly is that connected to? At what speed?

[lio1503]

@stephenw10

It's connected to my ISP router on 10G Ethernet port.

[stephenw10]

Is the ISP router actually routing? Is it actually linked at 10G?

One option here would be to just use one of the IGC ports. But that would be limited to 2.5Gbps of course.

[lio1503]

@stephenw10

No I just use ISP router for the PPPOE. Yes its linked to 10G.
Finally I order a XSPON module to completely bypass the ISP router, while waiting for the module to arrive I use the IGC port and it's works good.
Thanks you very much for your help.

[stephenw10]

Yup those RJ-45 SFP+ modules are not supported and actual function can be very variable. Some users have reported success with some modules but there's no real way to know any many don't work as expected.
