LAN interface going down

[malcom13]

Upgraded to 22.1 yesterday and I am seeing my internal VLANs go offline after a few hours. This is what the system.log is showing:

I am running suricata on the internal VLANs and suspect it may be related to the issue as a previous suricata update also caused a similar issue.

Any idea how I can investigate further?

Thanks!

Also running a Realtek NIC which could be the culprit. Changed from the re vendor driver to the built-in BSD driver. Will see how it goes.

Hi,


similar problem to me.
First, after hours, no DHCP from ISP (DOWN).
Somtimes no internet connection.
Tonight, can´t reach OPNSense.

How do you change the driver? I can login via ssh...

The builtin BSD driver appears to be more unstable. I ended up going back to the vendor re driver. I've also added the following options to /boot/loader.conf.local which I found in another thread. Hopefully this improves stability.

hw.re.msi_disable=1
hw.re.msix_disable=1
hw.re.eee_enable=0
hw.re.phy_power_saving=0
hw.re.phy_mdix_mode=0


[Bytechanger]

OK, you createt this new file?
/boot/loader.conf.local ??

How can I install the vendor driver?

I've installed the vendor driver too, but without these options. However, I set hw.re.max_rx_mbuf_sz="2048" in Tunables, because this was mentioned in the driver install message.

Let's see how stable it is...

[malcom13]

Yes, I created that file but I guess as fraenki mentioned, you can probably add it through Tunables. May also be worthwhile to try the max_rx_mbuf_sz option as well.

How can I install the vendor driver?

Install the plugin os-realtek-re.

[Bytechanger]

OK, thanks.
I´ve  overlook the plugin first time.

Should I try to use Tunables?
It´s better in updates I think and restore config..

Should I enter following?

Tunable: hw.re.msi_disable Value: 1
Tunable: hw.re.msix_disable Value: 1
Tunable: hw.re.eee_enable Value: 0
Tunable: hw.re.phy_power_saving Value: 0
Tunable: hw.re.phy_mdix_mode Value: 0
Tunable:  hw.re.max_rx_mbuf_sz Value: 2048


By the way, there is an red entry in my list:
NAme                        Description                             Type                Value
debug.pfftpproxy   Disable the pf ftp proxy handler.   unsupported   unknown

Definitely; do not modify files locally. Setting Tunables from the GUI is the better approach.
