Does not connect to switch after switch reset

stephenw10

Ok, so they are all Intel igc(4)?

Are you running 2.6?

What NICs are they? What is returned by: pciconf -lv?

stephenw10

Ok, so 5 igb NICs. But you say it has 8 ports total? If it has some sprt of internal switch that could be a problem.

rikinn55

@stephenw10
The Tp link has 8 and the qotom has 5

stephenw10

@rikinn55 said in Does not connect to switch after switch reset:

Qotom Mini PC w/8 ports

OK, that was just a typo then?

So what's logged when it disconnects and then re-links?

What does ifconfig -vvvm igc0 show? Assuming igc0 is one of the ports that's flapping?

rikinn55

@stephenw10
PfS_Gen_Log.txt
igc1 flags=8863UP,BROADCAST,RUNNING.txt

Hope these are the two items you want. If not please let me know where to find what your looking for.

Thanks

stephenw10

Hmm, OK so all the igc ports behave the same?

Before the reboot in that log we can see igc flapping every 5s or so.

After rebooting we see it flap once during the boot process then it stays up for ~2mins. Does it remain linked correctly after that?

rikinn55

@stephenw10
Yes it stays up every time. Seems a reboot of the Qotom is what is required. I tried reboot the TP Link but that failed getting it to relink.

rikinn55

@stephenw10
Didn't answer the first question. Keep in mind PfS isn't doing anything with ports 2-4. So if I pulg and unplug from them I always get a link right away. I have not set PfS to use any of those ports as LAN yet.

stephenw10

Ok, well first try re-assigning LAN as a different NIC and make sure that behaves the same.

The only time I've anything like this was when setting igc to 'autoselect' rather than 'default' in the config after having linked at 1G.

I note I do have hardware checksum off-loading disabled on test devices here. I wouldn't expect that to make any difference to linking but wort trying.

You can check the sysctls for igc1 like:

Here are the sysctls:
sysctl hw.igc.txt

Now I did a test by changing PfS to use igc.2 in place of igc.1 attached are resulting files.
After reboot.txt
After unplug igc.2 and plug back in.txt

As you will notice I experienced the same issue.

Thanks for all your help.

stephenw10

Hmm, looks near identical to any igc port I have here.

It does that when connected to anything? A host directly for example?

rikinn55

@stephenw10
I will check that in the morning.

rikinn55

@stephenw10
Ran the test with my laptop (intel nic) same result. See attached
Log 12APR23-a.txt

bingo600

I'm no FreeBSD/pfSense boot-log guru.
But wasn't it an 8-port Qotom ?

I only see it detect igc0..igc4 ... where are the last 3 net IF's ?

Could it be bad hw ?

/Bingo

rikinn55

@bingo600
I think that's what I said early on but it is a 5 port.

stephenw10

Can you get the log covering it start to fail after it has been stable?

So showing what is logged when you first disconnect and reconnect the cable.

rikinn55

@stephenw10
The file show a fresh boot through disconnect and reconnect then another fresh boot to bring everything back up.
