Logread | VTU member violation for vid 1, source port 1

I have some kern.err entries in my log (logread) that I don't understand.
Can someone tell me exactly what these errors mean and how to fix them.
The Google search did not bring any result that I could understand.

Are you using VLAN tagging with DSA?

Did you check the DSA tutorial on the wiki?

Yes, I use VLAN tagging with DSA and checked the DSA tutorial before I've done this.
See the 3 pics attaced below.

This is just a guess, but it might be worth checking.

This error is specific to Marvell 88E6xxx compatible switch chips and it occurs when the incoming frame’s VID is available in the VTU (VLAN Translation Unit), but the source port of the frame is not a member of the frame’s VLAN.

You didn't set the PVID on lan4.

If (and it’s a very big if) the port numbers are reversed and port 1 corresponds to lan4, you should check what VID is assigned to the untagged traffic, coming through lan4.

Install tcpdump, run tcpdump -ennqty lan4 and look for the packet's assigned VID.

It's not much, but it's a start...

There is something wrong here. If a port is a VLAN member and it is set as untagged, you should see the VLAN tag automatically added for the incoming packets, and removed for the outgoing.

I have a MT7621 device, and I can see the VLAN tags no matter if the PVID is set, or not.

In your case I don't see any tags at all. Probably if there is no tag set, it is assumed that the packet is a member of the default VLAN 1 (hence the error).

Set the PVID (list ports 'lan4:u*') and if the 802.1q tag doesn't show up, install the ip-bridge package and post the output of bridge vlan.

Sorry, i've corrected this instantly after reading your last post.

After installing the ip-bridge package, the router was rebooted.

I wonder little about this because it implies that the two devices connected to each other doesn’t have the same gateway setup. And if that happens you usually don’t have any workin network traffic at all.

What is on the other side of the cable on LAN4?

You could try power cycle the complete network so the dhcp leases are renewed if the clients run dhcp client mode and are stuck with some old leases.

The only way to overcome this different gateway dilemma is to run VLAN tagged trunk mode between two devices, router to switch for example.

You can use lan1, lan3 and lan4 as standalone interfaces. No need to put them in a bridge and separate them again with VLANs.

A Fritzbox is located on port 4 as an access device. Why should I make a trunk on port 4 when the Fritzbox is an access device from the port4 point of view? Apart from the fact that the Fritzbox cannot trunking.

How can I group multiple VLANs on port 3 if I have to use each port standalone?
Do you have a tip or an example?

Create new interfaces such as lan3.70, lan3.80

Sorry, but I have no Idea what u mean :slight_smile:
Can u give an example or screenshot?

I am at a loss at the moment... :confused:

How are you going to use the VLANs on lan3?

For LAN3, I need VLAN 60 as a native VLAN, and VLAN 70 and 80 as tagged VLANs.
This is because a Cisco access point (AP1) is connected to port 3 in root WGB (Work Group Bridge) mode.
The Cisco AP (AP1) provides three VLANS 60,70,80. VLAN 60 is AP1&2 management network, VLAN 70 is internal CLient network and VLAN 80 is client guest network.
Another Cisco AP (AP2) is connected to (AP1) as a WGB client and then an access switch is connected to AP2.

If you were using VLAN before, there should be interfaces named br-lan.5 br-lan.50 br-lan.60 br-lan.70 br-lan.80 for each VLAN.
As there is only one member per VLAN, you can just use standalone port mode;

br-lan.5 -> lan1
br-lan.50 -> lan4
br-lan.60 -> lan3
br-lan.70 -> lan3.70
br-lan.80 -> lan3.80
