pfSense 22.05 breaks VLANS, restoring pfSense 22.01 fixes the issue

@nrgia I am normally around all day, really all the time ;) Unless I get caught up in a real work thing - Fridays normally pretty light ;) Got a couple meetings on the cal, but cross fingers it will be a light day..

When it comes to hardware related stuff, or stuff that is most likely driver or hardware sort of stuff @stephenw10 is the guy! Now if I could duplicate the problem here I would be all in ;) But have not seen this issue and don't have anything that has that interface to play with even.

But always up for helping figure out a problem..

Lot of smart people around here - sure we can figure out what is going on.. Problem is might not be something that people get involved in - especially if they are not seeing the problem or don't have the hardware to try and duplicate. Steve seems to have everything ever made in his lab ;) heheh

The VLAN_HWTAGGING is a thing I would be interesting in looking into, I saw some stuff on the freebsd mailing list about that actually and the promisc setting.. You could put your interface into promisc mode and see if that corrects the problem - but that shouldn't need to be set as you see on my setup.. But it might be a work around for a driver issue?

I should be around trmw though - and happy to help if I can.. But hardware issues not really my "thing" if you will.. Especially if I don't have the hardware to duplicate it with.

stephenw10

I can definitely look into this. I'm not aware of any issue with ix and vlans though.

In fact I have one here and it's working fine:

@stephenw10 and no promisc set either ;)

stephenw10

Indeed, and it shouldn't need to be.

Something hardware specific perhaps? That's the SoC NIC in a 4100.

@stephenw10 @johnpoz
I appreciate your time guys.

This is the board if it helps
https://www.supermicro.com/en/products/motherboard/A2SDi-4C-HLN4F

Should I provide a TCP dump on vlan interface or on the native interface ?
I mean in my case ix2 or ix.20 ? Or both ?
Thank you

stephenw10

Look on the VLAN. If there's nothing there look on the parent for the tagged traffic. Or just do both anyway!

If you're doing that in the pfSense GUI be aware that you cannot (currently) apply filters when looking for tagged traffic. https://redmine.pfsense.org/issues/13094

NRgia

@stephenw10 I will use your cli command

tcpdump -i

I see it spits a lot of info, I will try to paste relevant info like in your example.

@nrgia make sure you add -e on tcpdump or it won't spit out vlan tag info

but isn't that 192.168.10 your vlan 20?

stephenw10

Yeah, so that looks expected for a dump inside the VLAN. Except there's only outbound traffic.

So run tcpdump -e -i ix2.20 and see if the tagged traffic is arriving.

NRgia

@johnpoz @stephenw10

Yes 192.168.10.1 is vlan 20

Here you go:

If it's not enough, tell me what to "grep" for, I dumped it to a file, due to too much lines.

Hmm, ~~so still only outgoing packets~~. At least as far as tcpdump can see.

Are you able to pcap on something upstream to see the tagged traffic that should be arriving there?

@stephenw10
Can you give me an example, please.
I don't have Wireshark installed.
I found it, it's in the UI, Packet capture

@nrgia said in pfSense 22.05 breaks VLANS, restoring pfSense 22.01 fixes the issue:

length 68: vlan 0, p 0, ethertype 802.1Q, vlan 20

That seems odd.. why is showing vlan 0 and vlan 20?

What is this guy 28:6d:97:7f:bb:0c, is that pfsense

That isn't outbound from pfsense.. Your other post shows ix2 as ether ac:1f:6b:45:fa:8a

A mac vendor lookup shows it as SAMJIN Co., Ltd.? Never heard of that company.
Seems "The Company provides its products mainly to Samsung Electronics."

Mmm, that is a very good point! Like it's QinQ.

@johnpoz If you must know 28:6d:97:7f:bb:0c is a Samsung Smarthings v3 Hub which is on vlan 20 :) It screams for Internet connection, but it doesn't get it :)

@nrgia but showing vlan 0 with a p0? But that is inbound to pfsense.. I don't have a lot of experience with setting priority on vlan 0, etc. But that could be maybe why pfsense not actually seeing the tag 20?
