DRA829J: CPSW9G behaving like a hub

Hi,

I just realized. The actual part number is "TDA4VH-Q1".

Hi Matthias,

I am assuming here that you have created a bridge interface and added all the required interfaces as its daughter interfaces. That is an important step for enabling switch mode in TDA4VH.

Please see here for more details on switch mode : https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-j784s4/11_00_00_08/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/Network/CPSWng-Native-Ethernet.html#cpswng-native-ethernet

If this is done, can you share the output of "ip -a" on linux.

I am suspecting that bridge is registered with its own separate MAC address and its not using the constituent MAC address of its daughter interfaces.

If eth1 is part of br0, can you try running the following command and see if it resolves the issue:

ip link set dev br0 address `ip link show dev eth2 | tail -1 | awk '{print $2}'`

Regards,
Tanmay

It seems this didn't fix the issue. Somehow it's just temporarily. I'm still looking into it.

After setting the MAC address of the switch to a MAC address of our VLAN interfaces, the duplication stops for about one minute. After that the duplication is back again.

Hi Tanmay,

The duplication is still happening and I analyzed it a bit further. 

- Without any changes to the MAC address of the bridge interface the duplication is happening for 240s and then stops for 60s and the cycle repeats.

- After changing the MAC address of our bridge interface the duplication stops for about 1min. This has no effect on the overall cycle of 240s duplication and 60s no duplication

- "bridge fdb show" shows no difference between the duplication and no duplication. 

- xf2 is the port on which the duplicated packets leave our board. "ethtool -d xf2" shows no entry for any of the affected MAC addresses.

I reduced our network configuration to better analyze the issue. 

- xf4 is the port on which the packets, addressed to kli, arrive

- The packets are duplicated onto xf2

- kli is a VLAN interface with VID 2

- koni is a VLAN interface with VID 3

- I check the duplication on another device connected to xf2

Hi Matthias,

Shouldn't the VLAN interfaces inherit the MAC address from switch interface. Their MAC addresses should be the same right.

Hi Tanmay,

I tried various combinations of MAC address assignments (even the impractical ones). The duplication still persists.

Hi Matthias,

This is weird. I couldn't see anything which can also explain this in The ALE entries. Can we have a call to debug this issue further.

Regards,
Tanmay

Hi Tanmay,

Sure. I have time for a call tomorrow. I guess you can see my e-mail address and send me an invitation?

Regards,

Matthias

Hi Tanmay,

I found the source of the pauses in duplication.

To check the duplications I used another Jacinto board with CPSW9G. After changing the MAC address the rx_port_mask_drop counter of the receiving board increases. So the duplication is still happening, I just can't see it with tcpdump.

I now use another machine and the duplication persists.

Regards,

Matthias

Hi Matthias,

Matthias Hörger said:

I found the source of the pauses in duplication.

But why would there be pauses for this. Are they coming when you change the MAC address?

About the call, I think we will be able to tomorrow 3pm IST. I think you are in europe time-zone. So should also be feasible  for you. Let me send you an invite over email.

Regards,
Tanmay

Hi Tanmay,

Yes, I have pauses when I change the MAC address. But I also have the pauses every 4 minutes. I don't really understand what's causing this. Since this is the receiving part for network packets, which are not addressed to this board, I'm not to concerned about it at the moment.

I was able to debug the our problem a bit further.

In MAC mode:

- When I change the MAC address of the bridge interface to the MAC address used by our VLAN interface (kli), the duplications stop.

In switch mode:

- Changing the MAC address of the bridge interface doesn't stop the duplications.

- However, if the MAC address of the bridge interface is different than that of the VLAN interface, I see every duplicated packet twice. Probably from the switch HW and linux settings. Changing the bridge MAC back to the same MAC as the VLAN interface, makes the second duplications disapear.

My conclusion so far is, that your first suspicion was correct. The different MAC addresses cause the duplication. In software, I can disable this by setting the same MAC addresses. But somehow this doesn't apply to the HW in switch mode. There the duplications persist.

Regards,

Matthias

Hi Tanmay,

I think the error is more or less clear to me now. 

In switch mode the ALE table of the switch doesn't contain any entry for the MAC addresses of the host system. This leads to the packets, addressed to the host, being send out on every port with the same VLAN ID. Which includes the host port and the port connected to the other system.

The question now is, is this expected behavior or is this a bug in the driver/switch HW? Can't the switch learn the addresses of the host port? To me it seems quite necessary, if the switch is operated in switch mode. 

Or did we miss some configuration?

Hi Tanmay,

We use SDK 11.0.0.21 (pdk_j784s4_11_00_00_21)

And here's the script from out call.

#!/bin/bash

ip link del dev switch

ip link add name switch type bridge
ip link set dev switch type bridge ageing_time 1000

ip link set dev xf2 down
ip link set dev xf4 down

devlink dev param set platform/c000000.ethernet name switch_mode value true cmode runtime

ip link set dev xf2 master switch
ip link set dev xf4 master switch

ip link set dev switch type bridge vlan_filtering 1
bridge vlan add dev switch vid 1
bridge vlan add dev switch vid 1 pvid 1 untagged self

ip link set dev switch up
ip link set dev xf2 up
ip link set dev xf4 up

ip a add "192.168.0.1/24" dev switch

Hi Tanmay,

I was able to create a functional configuration.

(I don't know why, but I can't insert code blocks anymore. So I have to post my script directly)

>>>>

#!/bin/bash
ip link set dev xf2 down
ip link set dev xf4 down

devlink dev param set platform/c000000.ethernet name switch_mode value true cmode runtime

ip link set dev koni up
ip addr add "172.30.0.1/16" dev koni

>>>>

This creates a bridge interface with the MAC of one of the switch ports and a VLAN interface with the same MAC. Unfortunately, this doesn't cover our use case. We need the switch ports "xf2" and "xf4" to have a separate MAC than the VLAN interface "koni". As soon as I change the MAC address from "koni" to a non-switch port one, we get the duplications.

I'm also a bit confused by the documentation to add another VLAN (3.2.2.10.3.2.3.1. CPSWng Native Ethernet — Processor SDK Linux for TDA4VM Documentation). It states these two commands have to be executed:

>>>>

bridge vlan add dev br0 vid 100 self <---- add VLAN as a Bridge Entry
bridge vlan add dev br0 vid 100 pvid untagged self <---- Add cpu port to VLAN100>

>>>>

To me, they both change the same value. This can also be observed with "bridge vlan show". But according to the comments and the documentation, they do two different things and are both necessary.

1. Is there a way to achive different MAC addresses for the switch ports and the VLAN interfaces without duplications?

2. What is the difference between the two similar looking commands?

Regards,

Matthias

Hi Matthias,

Matthias Hörger said:

Why is this required? In general, the bridge will adopt the hardware address of one the daughter interfaces and work with it. It isn't necessary to have a separate MAC address for bridge. It is not a separate hardware device.

Infact, once you have the bridge, the MAC addresses of other hardware interfaces are not used for anything L3+.

Currently with CPSW driver, there is no call back for setting bridge's MAC address. So for the routing table, its an unknown address, so it will be duplicated.

You can manually add the bridge's new MAC address to routing table and this should resolve the issue.

Regards,
Tanmay

Hi, Tanmay,

We use CPSW9G as a Profinet switch. This requires the VLAN interfaces to have a different MAC address than the switch ports. The MAC address of the bridge itself is not important.

Can you also comment on my second question? What is the difference between these two commands?

bridge vlan add dev br0 vid 100 self <---- add VLAN as a Bridge Entry
bridge vlan add dev br0 vid 100 pvid untagged self <---- Add cpu port to VLAN100>

They seem to set the same value.

Regards, 
Matthias

Hi Matthias,

Matthias Hörger said:

Can you also comment on my second question? What is the difference between these two commands?

So the first command will add the vid 100 to the switch as a registered vid for the br0 (host) port.

The second command will then do the following two things:

1. It will set the vlan id 100 to be pvid. i.e. All the traffic coming from any port will get the VLAN tag 100. Its not necessary to have the pvid tag. You can keep the pvid as 1 you would have done in the commands before this.
2. It will make all the packets with vid 100 egress as untagged packets. i.e., it will remove their VLAN tags for egress. So this depends on how you are using the VLANs. If its for the entire network, you would want this to be tagged, if its something to do with switch internal function, you can make it untagged.

Hope this clarifies things.

Regards,
Tanmay

Hi Tanmay,

Thanks for your reply. 

So these really are two separate commands? I really need to add the VID without any flags like "PVID" and "tagged/untagged" and then I have to change the setting with the second command?

If I understand you correctly I can ommit the PVID. I can keep it as 1 and don't have to set it when adding VID 100. I can also use "tagged/untagged" according to my use case.

So these are valid and necessary commands? I have to run both of them for the switch to work correctly?

bridge vlan add dev br0 vid 100 self
bridge vlan add dev br0 vid 100 tagged self

The fact that I specifically use tagged/untagged on the second command makes TI's switch behave differently when applying the configuration?

I always thought, omitting the "untagged" flag will set it to "tagged" by default.

Regards,
Matthias

Correct. You can tailor the bridge interface according to your needs.

Matthias Hörger said:

Yes. That would be the case.

Matthias Hörger said:

I need to check what the default behaviour is, but the tagged vs untagged will make the switch behave differently.

Tanmay

Hi,

Tanmay Patil said:

The default is tagged. But it doesn't hurt to specify.

Regards,
Tanmay

Hi Tanmay,

We still experience problems with this. Can you please provide me with your working configuration, so I can test it on my system?

Somehow we are missing something and can't pin it down.

Regards,

Matthias

Hi Matthias,

Sorry, I thought as we were talking on the other thread about bridge commands and this was resolved. Apologies for this oversight.

The following is exact script I have tested with linux kernel 6.6.32

ip link set dev eth1 down
ip link set dev eth2 down
ip link set dev eth3 down
ip link set dev eth4 down
sleep 1

devlink dev param set platform/c000000.ethernet \
name switch_mode value true cmode runtime

ethtool -L eth1 tx 8
ethtool -L eth2 tx 8
ethtool -L eth3 tx 8
ethtool -L eth4 tx 8
sleep 1

ip link add name br0 type bridge
ip link set dev br0 type bridge ageing_time 1000
ip link set dev eth1 up
ip link set dev eth2 up
ip link set dev eth3 up
ip link set dev eth4 up
sleep 5
ip link set dev eth1 master br0
ip link set dev eth2 master br0
ip link set dev eth3 master br0
ip link set dev eth4 master br0

ip link set dev br0 type bridge vlan_filtering 1
bridge vlan add dev br0 vid 1 self
bridge vlan add dev br0 vid 1 pvid 1 untagged self
sleep 1
ifconfig eth1 0.0.0.0
ifconfig eth2 0.0.0.0
ifconfig eth3 0.0.0.0
ifconfig eth4 0.0.0.0
ip link set dev br0 address `ip link show dev eth2 | tail -1 | awk '{print $2}'`
ifconfig br0 up
ifconfig br0 192.168.1.240

It works with this.

Can you check if only this script works for you? We can then discuss about MAC address management further after this.

Regards,
Tanmay

Hi Tanmay

Could you also test with SDK 11.0 (Linux kernel 6.12.17), please? That's what we are running here.

Sure, I will do that. It will take some time for me to get to it though. Please expect a response by Wednesday next week. In the meantime, do let me know if you are facing issues with this script as well.

Regards,
Tanmay

Hi Tanmay,

Thanks for the configuration. I will test it on our system.

Could you also provide a working configuration with two separate VLANs for eth1/eth2 and eth3/eth4. As this is closer to our use case and the part were we experience basically all of our problems. Unfortunately, to me the documentation is not clear enough on how to achive the correct switch configuration for this use case.

I.e.:

- eth1 and eth2 use VID 2 and connect to a virtual VLAN interface iface1 with VID 2. Egress on eth1/eth2 is untagged and PVID is 2.

- eth3 and eth4 use VID 3 and connect to a virtual VLAN interface iface2 with VID 3. Egress on eth3/eth4 is tagged and there is no PVID.

- br0 has no IP and iface1 and iface2 lie in two separate subnets

Here a picture describing our scenario:

Regards,

Matthias

Hi Tanmay,

This configuration works. 

Please try to implement the use case I described.

Regards,

Matthias
