How To Disable/Enable Energy Efficient Ethernet (EEE)?
-
Well, yes, technically I'm not using a 4 port network "card." Like you, I am using one of those popular DIY AliExpress fanless industrial PCs that include 4 ports. Also just FYI, there are 4 port i226 cards that you can buy (see here).
So, it sounds like we are having similar issues. The port that I use to uplink with my Qnap 2.5gbe switch keeps disconnecting 1 or 2 times a day. I too have tried turning off everything, and playing around with every setting I can think of on both the switch and the router. I have a feeling its going to comes down to either buggy Intel i225/i226 network adapters and/or an incompatibility with my switch. Before the Qnap switch, I had a Mikrotik 1gb 24 port switch that ran just fine. I'm told it was probably fine due to the fact that the router was connecting at 1gbe instead of 2.5gb. Apparently, a lower link speed is more stable. Strangely enough, when I uplinked the router to my Qnap switch using one the the 10gbe ports (obviously only connecting at 2.5gbe) it seem to run way more stable. Maybe the 10gbe ports are using different/better chipset and is more "compatible"? Just wanted to throw that out there.
OK, so back to my post. Disabling EEE was yet another attempt to see if I can get some stability with my uplink. If anyone is out there that can confirm my understanding of my current EEE settings, that would be fantastic. : -)
Thanks!

@uplink
BOTH sysctl dev.igc.0.eee_control and sysctl hw.igc.eee_setting should be 1 to disable EEE. -

It's very possible that both variants have asmedia pci-e bridge
There is one review of similar card like I have. Google translated versionIt can be i226 chip itself or this Asmedia bridge or both anyway. That's why I created my own topic to ask people do they have similar problems with 225 or 226 cards, but no one answered so far. I know that Netgate uses same 225/226 series and the FreeBSD driver exists only because of them. I have not seen that somebody reported similar issues on Netgate-made appliances. Furthermore, I have even updated firmware on the 225 version of card to the latest available firmware. No luck.
In my case the link drops only on one port where PPPoE is running or igc0. Never on igc1. -
EEE is disabled by default in igc in FreeBSD. The description text for 'hw.igc.eee_setting' is incorrect. That should be 1 to disable it as mentioned.
-
Just to be 100% clear, you're saying there is a typo in the description for the hw.igc.eee_setting? So, it should read "Disable Energy Efficient Ethernet" instead of "Enable Energy Efficient Ethernet"? If that's true then, yes, my EEE configuration should be all disabled then.
Should I bug in a bug ticket, or is there already on made for this?
Thanks!
-
Yes I believe so:
https://github.com/freebsd/freebsd-src/blob/main/sys/dev/igc/if_igc.c#L266It should probably be an upstream bug too. It doesn't look to have been fixed there yet.
Either way it's disabled by default in pfSense so isn't causing whatever you're seeing there.

Hey @uplink - I think I'm experiencing the same issue: a cheap 4 port Inter 226i unit from Aliexpress works almost flawlessly, except for sporadic cutouts that last precisely 14 seconds almost every time. This has a nack of happening when on voip calls (slack/zoom/whatsapp/etc), although it can happen anytime. Here is a screenshot from Ping Doctor: the ping to the router seems fine, but the internet part is down. I also get dpinger issues:
send_interval 500ms loss_interval 2000ms time_period 60000ms report_interval 0ms data_len 1 alert_interval 1000ms latency_alarm 500ms loss_alarm 20% alarm_hold 10000ms dest_addr 100.64.123.253 bind_addr 100.67.44.144 identifier "FIBER_PPPOE "were you ever able to resolve this issue?
-
Does it actually lose link? Anything logged in pfSense?

Hey @lazyt
Just real quick, the back story on this thread is that I was trying to figure out if EEE was possibly causing my random disconnects/drops which manifest in the pfSense logs as "hot plug" events. I went through a lot of troubleshooting with the members on this forum (many thanks), but to no avail. However, I would highly recommend that you read my post below and try out some of the troubleshooting there, maybe something will work for you.
My journey with the disconnects:
https://forum.netgate.com/topic/182384/help-random-hot-plug-events/7?_=1709917518893So, to answer your question, I did not discover the root of the disconnects, but I did come up with a workaround. I ended up connecting my AliExpress router's 2.5gbe port to a port on my switch via a RJ45 SFP+ transceiver module that was capable of auto negotiating down to 2.5gbe. I've been running this configuration for nearly 6 months now without drops. It's not ideal since it occupies one of my precious SFP+ ports on my switch, but it works. Its funny you revived this old thread, because just last week I was thinking of trying to get this to work again.
Can I ask, are you seeing "hot plug" events in your pfSense logs when you experience these disconnects? What switch are you using?

I don't think so - in which log did you see them?

You can find the "hot plug" events in the system logs by navigating to: Status > System Logs > System > General
Below is an example of what you are looking for. You will see the link state change to "down" and a hot plug event. Keep in mind these logs only show you the last 500 events. So, usually you only have a day or two worth of logs. It's best to check right away when you experience a disconnect.

@uplink no, not seeing hot plug events

Interesting. OK, so at this point, maybe we should get a better understanding of what's going on. It sounds like you have a different issue than the one I was having. I was losing all network connectivity between my AliExpress router and my QNAP switch.
Since I'm not familiar with Ping Doctor, could you explain how you are testing your internet connection with it. It sounds like you are maybe running Ping Doctor on a PC and that pings your router's IP address? But, randomly the internet will go down for 14 second, even though you can still ping the router? Is that correct?
The 14 second duration seems suspect to me. Reminds me when I experienced something similar where an application running in pfSense would bring down my WAN interface while updating. However, this was easy to track down since it was happening at the same time everyday. You can read about it below:
https://forum.netgate.com/topic/177485/suricata-rules-update-drops-internet-connection-briefly/12?_=1710097873521
I understand that duration is 14 seconds, but is the frequency (when they occur) random or repetitive? Sometimes if can identify a pattern, it can give us a clue. If you feel comfortable, you might post a chunk of your system log (same location I mentioned previously) from the exact timeframe you had a disconnect. We might be able to spot something you missed.
-
@uplink PingDoctor is an app that runs continuously, runs traceroute, and graphs the results. This allows me to visualize the point and duration of the outage.
Unfortunately, the outages don't seem to have a pattern, although they seem to happen more often during VoIP calls (Whatsapp/Zoom/Slack/etc.).
Here are the logs from the time of an outage:

That looks like it just starts dropping packets on the fibre WAN and switches to the DSL WAN. That is the expected behaviour in that situation.
The first thing I would do there is change the monitor IP on the Fiber WAN to something external. Using the default WAN gateway IP can produce bad data. The gateway may not respond to pings when loaded. Or at all for that matter, though here it clearly does most of the time.
-
@stephenw10 I had it on something external for a long time. Will switch it back and try again. Also, I disabled monitoring totally for a bit - also didn't help.
-
With monitoring disabled then did the PPPoE session fail entirely and then reconnect? That isn't what's shown in the above log.
-
@stephenw10 No - I currently do have a monitor in place. I was just commenting that in the past I had tried removing the monitor and I still experienced the same issue
-
Ok well we'd need to see what is logged in that situation then since without monitoring it would not throw a gateway alarm and that's what's causing the issues you're seeing now. Assuming there is no loss of link logged before that which is omitted from the logs you posted.
