Tool/software:

Hi,

In our design we are using AM6412 with DP83867 Phy. Our product has two ethernet interfaces eth0 and eth1.

We are using kernel version 6.1.80-rt26.

When we have PTP running on eth1 (and synced), if we change the link state of eth0 interface, the ptp sync on eth1 interface will be lost and never recovers.

To restore the sync we need to perform any of the following activities

1. Restart the PTP

2. Run "ifconfig eth1 up" (Please note it is eth1, the interface which was already up and had PTP sync working)

3. Turn on Promiscuous mode "ip link set eth1 promisc on"

Further debugging revels that the issue is somehow related to ALE functionality. When the PTP sync is lost we see that following two counters are incremented

ale_drop: 37378
rx_port_mask_drop: 37378

Some other observations:

1. Sync is lost when the other interface is brought down or up (i.e. any change in state)

2. Sync is not restored even when the other interface is set to the original state when PTP was working.

3. This example show PTP running on eth1 and change of the state of eth0, same behavior is observed when the interfaces are interchanged.

Hello Dipal,

Dipal Zambare said:
In our design we are using AM6412 with DP83867 Phy. Our product has two ethernet interfaces eth0 and eth1.

Can you describe your test topology? What devices do you have connected to the eth0 and eth1 ports? Is it a line or ring topology?

Are you using CPSW ethernet or PRU_ICSSG ethernet interfaces for eth0 and eth1? (Based on the PTP log output I'm assuming CPSW ethernet for both interfaces?)

Is the custom AM6412 device serving PTP grandmaster or as a PTP follower?

What specific steps and Linux commands did you use to start the PTP test?

Can you share the full PTP log (please use Insert > Code instead of directly pasting into the response)?

Hi Daolin,

Thanks you checking this.

1. We tested this in two topologies as given below (Blue box is the Device in test), all logs in this thread are based on topo 2.

Topo 1:

Topo 2:

2. We are using CPSW driver for both ports on the DUT

3. The PTP role doesn't matter, we observe issue in both cases i.e. DUT is PTP grandmaster or PTP follower.

4. Following command are used to start PTP, no other configuration is done:

DUT : ptp4l -2 -P -H -i eth1 -m -q -l 7 -s

PC : sudo ptp4l -2 -P -H -i enp8s0 -m -q -l 7

Please find below logs form both PC and DUT, please check "<<<<" for annotations

Hi Dipal,

Thanks for providing these additional details.

Dipal Zambare said:
all logs in this thread are based on topo 2.

Are you trying to test some sort of Ethernet redundancy scheme with topology 2 while running PTP?

What happens if you had kept eth0 disconnected before running the ptp4l synchronization?

Dipal Zambare said:
DUT : ptp4l -2 -P -H -i eth1 -m -q -l 7 -s

PC : sudo ptp4l -2 -P -H -i enp8s0 -m -q -l 7

With these ptp4l options, if eth1 was disconnected instead of eth0, do you see similar log outputs? If possible, can you show the log for this case as well? I'm assuming instead of "port1 (eth1): delay timeout" something like "port0 (eth0): delay timeout" would show up?

Have you tried using "ptp4l -2 -P -H -i eth0 -i eth1 -m -q -l 7 -s" for DUT and "sudo ptp4l -2 -P -H -i enp6s0 -i enp8s0 -m -q -l 7" for PC?

Hi Daolin,

We are not trying to us any redundancy, enp6s0 - ETH0 has no part in PTP, I just made this topo so that it is easy to test. However, we have observed same behavior in Topo 1 as well even through eth0 and eth1 are connected to completely different devices.

If eth1 is disconnected, the PTP never recovers (there are no messages related to eth0), please find below the logs for both grand master and follower (DUT) for this scenario, check "<<<<" for annotations.

PC (PTP Grand master)

Have you tried using "ptp4l -2 -P -H -i eth0 -i eth1 -m -q -l 7 -s" for DUT and "sudo ptp4l -2 -P -H -i enp6s0 -i enp8s0 -m -q -l 7" for PC?

I believe this will configure devices in PTP transparent clock which is not relevant to our scenario and the other link is merely used for ssh connection and it is not supposed to have any PTP running.

EDIT:

When the sync is lost (after eth1 is made up again) we again see the same drop counters are incremented.

root@ptp_test:~# ethtool -S eth1 | grep drop | grep -v ": 0"
ale_drop: 1807
rx_port_mask_drop: 1807

Hi Dipal,

Dipal Zambare said:
We are not trying to us any redundancy, enp6s0 - ETH0 has no part in PTP, I just made this topo so that it is easy to test. However, we have observed same behavior in Topo 1 as well even through eth0 and eth1 are connected to completely different devices.

Thanks for this clarification

Dipal Zambare said:
If eth1 is disconnected, the PTP never recovers (there are no messages related to eth0), please find below the logs for both grand master and follower (DUT) for this scenario, check "<<<<" for annotations.

This is a little confusing to me. I was under the impression that since eth1 is used in the ptp4l configuration, eth1 is a necessary interface to keep ptp synchronization running and that the issue lies in eth0 (unrelated to PTP configuration) being disconnected (not eth1 being disconnected).

Daolin Qiu said:
What happens if you had kept eth0 disconnected before running the ptp4l synchronization?

What happens if you done this, making sure to keep eth1 connected throughout the whole test?

Based on your request in previous reply, quoted below, I though you wanted me to check by disconnecting eth1? However, it has discovered new issue that ptp never resumes.

Daolin Qiu said:
With these ptp4l options, if eth1 was disconnected instead of eth0, do you see similar log outputs? If possible, can you show the log for this case as well? I'm assuming instead of "port1 (eth1): delay timeout" something like "port0 (eth0): delay timeout" would show up?

If we interchange eth0 interface with eth1, the behavior is exactly similar, we can replace eth0 <-> eth1 in all logs accordingly.

Anyways here is the summary of original issue we had:

eth0 is physically disconnected before starting PTP
1. Start PTP on eth1, ensure it is working properly
2. reconnect eth0 cable
3. eth0 is back online
4. PTP stops working on eth1
eth0 is connected and up before starting PTP
1. Start PTP on eth1, ensure it is working properly
2. Disconnected eth0
3. PTP stops working on eth1
4. Reconnect eth0
5. PTP still doesn't work on eth1

If we swap eth0 with eth1 we will observe the same behavior (i.e. eth1 state will stop PTP operation on eth0).

For these scenarios PTP will start working if I do any of following

Restart the PTP
Run "ifconfig eth1 up" (Please note it is eth1, the interface which was already up and had PTP sync working)
Turn on Promiscuous mode "ip link set eth1 promisc on"

Now when I try to change the state of eth1 itself (where PTP is running), we found another issues (eth0 has no role in this scenario):

Change eth1 state by Physically disconnecting the cable
1. Start PTP on eth1, ensure it is working properly
2. Physically disconnect the eth1 cable
3. Wait for 1 minute (PTP will not work as cable is disconnected)
4. Reconnect the eth1 cable
5. PTP sync is restored
6. Everything is working as expected here
Change eth1 state over CLI (cable remains connected):
1. Start PTP on eth1, ensure it is working properly
2. Bring down eth1 interface using cli "ifconfig eth1 down"
3. Wait for 1 minute (PTP will not work as cable is disconnected)
4. Bring up eth1 interface using cli "ifconfig eth1 up"
5. PTP never recovers (this is the issue reported in my last reply)
6. Only way to make PTP work again is to restart the PTP process, interface state, promiscus mode doesn't help

I see, there was a misunderstanding. What I meant was if you could use "ptp4l -2 -P -H -i eth0 -m -q -l 7 -s" and disconnect eth1 and show exactly what the logs are. I know that you have stated the behavior is similar if the interfaces are switched but I would like to see the log as well for the switched case.

Thanks for making clear the sequence of steps to observe the various issues you specified. Are eth0 and eth1 interfaces in dual mac mode or configured as a switch?

I will try on my side if I can reproduce the issue, most likely I will not get to this until Friday. Please kindly ping this thread if I haven't responded on Friday.

HI Daolin,

No problem, I realized later what you were trying to find out.

So I update the topology as:

Hi Dipal,

I still need to test on my end. However, I see from your log "Eth0 was made up (Again) here". This is confusing to me because it was indicated to me that eth1 was the one that was made down and back up. Just to be clear, ONLY eth1 was disconnected in the logs above and eth0 was always kept connected?

Hi Daolin,

Your understanding is correct, eth0 is always up. In short "ipconfig eth0 up" (even though eth0 interface is already up) does something which make PTP packets to flow again.

What happens is this

eth0 is up and has PTP working as expected, eth1 is also up at this state
eth1 link state is changed from up to down -> PTP stops working on eth0
eth1 link state is changed from down to up -> PTP still doesn't work on eth0
Now if you run "ifconfig eth0 up" we see that PTP syncs again (eth0 interface was always up, this command is redundant but it make PTP work again without restarting the PTP process.) As noted by you, we don't see any logs related to eth0 but PTP starts working.

After step 2 in above sequence, there are thee ways to make PTP work again

Run "ifconfig eth0 up"
Run "ip link set eth0 promisc on"
Stop PTP process on DUT and start again.

My analysis is that there is some configuration in the ALE which prevents PTP multicast packets to reach CPU, and this configuration is corrected by these commands, that's why when promiscus mode is enabled we don't see this issue as nothing is dropped by ALE.

Hope it is clear now.

Regards

Hello Dipal,

I ran the same ptp4l test on my setup of two AM64x EVMs connected eth0 to eth0 and eth1 to eth1 and configuring the eth1 interface in the ptp4l command. The Linux kernel I'm using the is the same as provided in the latest SDK RT-Linux 10.01 (kernel 6.6).

You can see from the log when I disconnected the eth0 interface. Even after disconnecting the eth0 interface OR bringing the interface down with "ip link set dev eth0 down", I don't see the same continuous "delay timeout" message that you saw when the opposite interface was disconnected.

Even when I tried configuring eth0 for the interface used for ptp4l and disconnect or bring down the eth1 interface I don't see the same sequence of "delay timeout" messages you shared seeing.

We are using kernel version 6.1.80-rt26.

Can you give the latest SDK 10.1 a try? This would be kernel version 6.6.

Hi Daolin,

Thanks for checking it out and the update, I will try with the latest Kernel, i will need couple of days to get back on this.

Meanwhile it will be really helpful if you can verify the following scenario as well.

Now when I try to change the state of eth1 itself (where PTP is running), we found another issues (eth0 has no role in this scenario):

Change eth1 state by Physically disconnecting the cable

Start PTP on eth1, ensure it is working properly

Physically disconnect the eth1 cable

Wait for 1 minute (PTP will not work as cable is disconnected)

Reconnect the eth1 cable

PTP sync is restored

Everything is working as expected here

Change eth1 state over CLI (cable remains connected):

Start PTP on eth1, ensure it is working properly

Bring down eth1 interface using cli "ifconfig eth1 down"

Wait for 1 minute (PTP will not work as cable is disconnected)

Bring up eth1 interface using cli "ifconfig eth1 up"

PTP never recovers (this is the issue reported in my last reply)

Only way to make PTP work again is to restart the PTP process, interface state, promiscus mode doesn't help

Regards,

Hello Dipal,

Please find the below logs where I replicated the two sequence of tests you specified.

The results don't have the same exact behavior that you had shared previously. Try and see if the latest SDK will help resolve the issue from showing up.

NOTE: I used "ip link set dev eth1 down/up" instead of "ifconfig eth1 down/up" as the ip command (from iproute2 package) is the most up to date command to use. ifconfig in Linux is no longer the most up to date command to use.

Hi Daolin,

Thank you very much for checking this out

This is ok and correct.

I will keep you posted on the progress from my side.

Hi Daolin,

We need to fix this issue by end of February.

I got my setup with TI -SK-AM64 up and did some more analysis, i believe there are still some issues.

Daolin Qiu said:
You can see from the log when I disconnected the eth0 interface. Even after disconnecting the eth0 interface OR bringing the interface down with "ip link set dev eth0 down", I don't see the same continuous "delay timeout" message that you saw when the opposite interface was disconnected.

If you see the logs share by you with the above message:

After the port state change we get

ptp4l[180.367]: port 1 (eth1): delay timeout
ptp4l[180.368]: delay filtered 411 raw 411

But we do not get (master offset message) as below

ptp4l[157.332]: master offset -7 s2 freq -2155 path delay 409

This means that PTP is still not synced with the master.

I re-created this exact scenario on AM-64EK (I am using eth0 for PTP and eth1 to change link state)

Please find below the logs attached

Checking the stats points to the same counters

root@am64xx-evm:~# ethtool -S eth0 | grep drop | grep -v 0
ale_drop: 3873
rx_port_mask_drop: 3873

and 'ip link set dev eth0 up' will fix the problem.

Can you please verify this on your setup once, if you run ptp follower with log level 6 it will be easier to verify?

Hi Dipal,

Looking back on my shared logs, it appears that the max offset message shows up for the below scenario on the follower device.

Dipal Zambare said:
Change eth1 state by Physically disconnecting the cable

Start PTP on eth1, ensure it is working properly

Physically disconnect the eth1 cable

Wait for 1 minute (PTP will not work as cable is disconnected)

Reconnect the eth1 cable

PTP sync is restored

Everything is working as expected here

Change eth1 state over CLI (cable remains connected):

Start PTP on eth1, ensure it is working properly

Bring down eth1 interface using cli "ifconfig eth1 down"

Wait for 1 minute (PTP will not work as cable is disconnected)

Bring up eth1 interface using cli "ifconfig eth1 up"

PTP never recovers (this is the issue reported in my last reply)

Only way to make PTP work again is to restart the PTP process, interface state, promiscus mode doesn't help

For the other scenario (quoted below) I do see that the max offset message is missing following the disconnection.

Dipal Zambare said:
What happens is this

eth0 is up and has PTP working as expected, eth1 is also up at this state

eth1 link state is changed from up to down -> PTP stops working on eth0

eth1 link state is changed from down to up -> PTP still doesn't work on eth0

One other test to try is to use "ptp4l -P -2 -H -i eth0 -f gPTP.cfg --step_threshold=1 -m -q -p /dev/ptp0" where gPTP.cfg is the below. For the grandmaster device set "priority1" to 100 and for the follower, set "priority1" to 240. What happens when you try the above two scenarios? Do you still see the same issue?

I will try to test it out tomorrow. I will also try to check the ethtool drop counters as well tomorrow.

Hi Dipal,

Can you give the latest SDK 10.1 a try? This would be kernel version 6.6.

Were you able to give SDK 10.1 a try? I'm assuming the recent behavior was observed on this SDK version?

Daolin Qiu said:

I tested it out and see similar results to your log. For the ethtool drop counters, I notice these increment as long as there is a link up event, even if PTP was not running. Below is some information I could find on portmask drop and ale drop from the AM64x TRM. I don't think these are a PTP specific issue.

I tested this ptp configuration and it does not seem to show the same issue of ptp sync loss when eth1 is disconnected. It may be a solution for you to try out.

Hi Daolin,

Thanks a lot for the details, Unfortunately, I am still stuck with kernel version 5.10 (I am not sure about the SDK version) on TI AM64-SK, My AM64-SK is not able to boot with the latest SDK, we procured new AM64-SK to expedite.

On our custom design we use mainline kernel version 6.1.80, this also i am trying to update to 6.6+, it is also work in progess.

Nevertheless there is progress:

The following command and a configuration file does prevent the issue:

ptp4l -P -2 -H -i eth0 -f gPTP.cfg --step_threshold=1 -m -q -p /dev/ptp0

After debugging i found the the main config helping in resolving the issue is

ptp_dst_mac 01:80:C2:00:00:0E

If I remove this and keep everything same, i still see the issue.

I need to do some more tests to ensure that we can use this workaround.

Regards,

-Dipal

P.S. I needed to change neighborPropDelayThresh to 4000 from 800 in my configuration, without this PTP sync is never established in my setup.

Thanks for sharing this piece of information. If you haven't already seen, the ptp4l man page describes "ptp_dst_mac" as "The MAC address to which PTP messages should be sent. Relevant only with L2 transport. The default is 01:1B:19:00:00:00." My guess is that since the "-2" option is used, the "ptp_dst_mac" is a required configuration. The issue you are seeing is indicating that the default ptp_dst_mac is a potential issue, it may be worth checking specifically what 01:1B:19:00:00:00 MAC address is.

This is interesting, might be worth looking into what this configuration means. According to the manpage, it is relevant when 802.1AS is used, selected by "transportSpecific" configured as 0x1.

Let us know if you have further questions.

Hi Daolin,

We noticed that this issue also has tight coupling with systemd-networkd, in our configuration we are using NetworkManager.

I observed this issues again in following scenarios

1. We dont use any network manager i.e. both systemd-networkd and NetworkManager are disabled

2. We use NetworkManager to manager the interface configuration.

I also tried to configure NetworkManager to ignore eth1 interface by configuring it to be an unmanged interface

unmanaged-devices=interface-name:eth1


This can be tested by disabling systemd-networkd on the AM64-SK.

Since we need to use NetworkManger, are there any know issues or suggestion to workaround this?

Thanks & Regards,

To clarify, you are seeing the issue with which ptp4l command? That is, the one using gPTP.cfg or the one you previously was using (without gPTP.cfg)?

The issue is seen with the ptp4l with gPTP.cfg

ptp4l -P -2 -H -i eth0 -f gPTP.cfg --step_threshold=1 -m -q -p /dev/ptp0

Hello Dipal,

Dipal Zambare said:

Unfortunately, since we don't appear to be using NetworkManager on our Linux SDK, we weren't aware that this issue would be seen if systemd-networkd was not running.

I would suggest taking a look at the difference between NetworkManager and systemd-networkd to see if there is any difference in the way it handles a link being dropped and reconnected and see if NetworkManager has a way to perform the same way as systemd-networkd.

Is there a particular reason why you must use NetworkManager and not systemd-networkd?

Hi Daolin,

We are using NetworkManager as it helps us to handle different network configurations required by our customers better.

As per my investigation the root cause is that the multicast is disabled on the interfaces when any one of them goes though a state change.

Systemd-networkd: It works because systemd-networkd specifically adds membership for PTP mutlicast address (01:80:C2:00:00:0E) when the interface states are changed.
Running "ip link set dev ethX up" or "ifconfig ethX up" enabled IP multicast on the interface similar to running "ip link set dev eth1 multicast on"

Unfortunately we don't see this in interface state (multicast is always shown as enabled, when when muticast packets are dropped)

root@ptp_test:~# ip link show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
    link/ether 54:3b:30:01:18:ee brd ff:ff:ff:ff:ff:ff
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
    link/ether 54:3b:30:01:18:ef brd ff:ff:ff:ff:ff:ff
root@smartnc:~#

I managed to get this to work with NetworkManger (or perhaps independent of any network management) by configuring the static entry for the PTP muticast address as given below, i still need to configure it for both interfaces even though i am running PTP on one interface only.

ip link set dev eth0 down
ip link set dev eth1 down
ip maddr add 01:80:c2:00:00:0e dev eth0
ip maddr add 01:80:c2:00:00:0e dev eth1
ip link set dev eth0 up
ip link set dev eth1 up

I feel there is still something missing / can be improved on how this is handled by the TI drivers.

Did you get to investigate this further, the issue is not only limited to the PTP multicast, it is applicable to other mutlicast packets as well. Once the link state changes the multicast packet flow stops.

Since the multicast applications can use any mutlicast addresses we will not be able to add static entries for all of them (and it doesn't sound correct as well).

To remind and hint: Enabling Promiscuous mode prevents all these issues.

Let me know if you need any more information.

Hi Dipal,

Dipal Zambare said:
After debugging i found the the main config helping in resolving the issue is

ptp_dst_mac 01:80:C2:00:00:0E

If I remove this and keep everything same, i still see the issue.

You mentioned previously that by removing this PTP configuration, you still see the issue. I'm wondering if this configuration plays an important part in the PTP multicast address issue you are mentioning. Is keeping this PTP configuration not an option for your application?

Dipal Zambare said:

Since the TI SDK does not implement NetworkManager but rather uses systemd-networkd and the use of NetworkManager is simply a requirement of your application, we don't provide specific support on trying to change the TI software to support a customer specific application.

Dipal Zambare said:

Can you share the logs for the non-PTP multicast packet case where you are seeing issues with link state change?

We need to keep this configuration anyways as it is part of gPTP profile.

Since beginning i am suspecting there is basic issue with multicast handling/mac learning in general, i think NetworkManger just exposed the issue but not introduced it.

There are multiple symptoms which points to this.

1. The counters, it clearly says that packets are dropped by ALE

ale_drop: 1807
rx_port_mask_drop: 1807

2. Turning on promiscus mode solved the issues: ALE filtering is turned off in this case.

3. "ip link set dev eth1 multicast on" this also solves the issue.

When i said something is missing in TI drivers i meant this part, i don't think it has any dependency on network manager.

Even with systemd-networked this fails if you are not using the gPTP profile, don't you think it is a problem?

I will share the logs for other mutlicast cases, hopefully that should make it clear.

Dipal

Hi Dipal,

If it is truly a problem unrelated to just the specific use case of PTP and your NetworkManager application and related to general multicast handling, then it is a problem we have to address. However, as a first step I will need to be able to also see the issue occur on a basic multicast test (without any PTP running) on my test environment. That is why I ask for the logs and if you can share the steps you took to test that it is applicable to other multicast packets as well. This will help me try to recreate the problem specifically showing that without PTP, the problem still persists, so that I can discuss internally where the issue is, if it is indeed an issue with the CPSW driver.

Dipal Zambare said:

From my understanding, we have only tested a very basic test of PTP on our devices, which most likely does not include disconnecting and reconnecting the other interface as you tested here. The only PTP configuration we have tested more extensively is the gPTP profile I shared because I am the main person testing it out. But since you mentioned the root cause is likely to be a general multicast issue unrelated to whether PTP is running or not, if I can get more details on being able to see this, I will be able to get more help internally to see if the problem is a CPSW driver issue.

Hi Daolin,

I was able to produce this issue with simple multicast ping.

Hardware setup:

Software versions:

SDK: 11.00.09.04
Kernel: 6.12.17-ti-rt-00771-gc85877d40f8e
Hardware: SK-AM64B

Steps to produce the issue with generic multicast

1. Enable multicast ping

sysctl -w net.ipv4.icmp_echo_ignore_broadcasts=0

2. Join a multicast group and verify group Membership

ip addr add 224.10.10.10/24 dev eth1 autojoin
ip maddr show dev eth1

3. Ping the multlcast group IP from the peer:

ping -i enp8s0  224.10.10.10

4. Change the state of other interface (eth0 in this setup)

ip link set dev eth0 down

5. Observe that

On peer/wireshark ping responses are stopped
Drop counters are getting incremented
root@:~# ethtool -S eth1 | grep drop | grep -v 0
ale_drop: 61
rx_port_mask_drop: 61

The resolution remains same, one of the following steps can resume the ping responses

Enable multicast "ip link set dev eth1 multicast on"
Force link up again (even though it is already up) "ip link set dev eth1 up"
Enable promiscus mode: "ip link set dev eth1 multicast on"
Configure static group membership (needed on both eth0 and eth1) "ip maddr add 01:00:5e:0a:0a:0a dev eth0" and "ip maddr add 01:00:5e:0a:0a:0a dev eth1"

Please find attached logs from my setup as well.

1. Enable icmp echo for multicast

    root@am64b_sdk11:~# sysctl net.ipv4.icmp_echo_ignore_broadcasts
    net.ipv4.icmp_echo_ignore_broadcasts = 1
    root@am64b_sdk11:~# sysctl -w net.ipv4.icmp_echo_ignore_broadcasts=0
    net.ipv4.icmp_echo_ignore_broadcasts = 0
    root@am64b_sdk11:~# sysctl net.ipv4.icmp_echo_ignore_broadcasts
    net.ipv4.icmp_echo_ignore_broadcasts = 0

2. Join multicast group
    root@am64b_sdk11:~# ip maddr show dev eth1
    3:      eth1
    		link  01:00:5e:00:00:01
    		inet  224.0.0.1
    root@am64b_sdk11:~# 
    root@am64b_sdk11:~# ip addr add 224.10.10.10/24 dev eth1 autojoin
    root@am64b_sdk11:~# ip maddr show dev eth1
    3:      eth1
    		link  01:00:5e:00:00:01
    		link  01:00:5e:0a:0a:0a                                   <<< New group
    		link  01:00:5e:00:00:fc
    		link  01:00:5e:00:00:fb
    		inet  224.0.0.251
    		inet  224.0.0.252
    		inet  224.10.10.10                                        <<< New group
    		inet  224.0.0.1
    root@am64b_sdk11:~# ip addr show dev eth1
    3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
        link/ether 54:3b:30:01:18:ef brd ff:ff:ff:ff:ff:ff
        inet 224.10.10.10/24 scope global autojoin eth1
           valid_lft forever preferred_lft forever
        inet 192.168.1.20/24 scope global eth1
           valid_lft forever preferred_lft forever


3. Change link state of eth0
    root@am64b_sdk11:~# ip link set dev eth0 down
    root@am64b_sdk11:~# [ 1968.291443] am65-cpsw-nuss 8000000.ethernet eth0: Link is Down

4. Observe drop counters

	root@am64b_sdk11:~# ethtool -S eth1 | grep drop | grep -v 0
	 ale_drop: 8
	 rx_port_mask_drop: 8
	root@am64b_sdk11:~# ethtool -S eth1 | grep drop | grep -v 0
	 ale_drop: 11
	 rx_port_mask_drop: 11
	 
5. Enable mutlicast on eth1 to resume packet flow

    root@am64b_sdk11:~# ip link set dev eth1 multicast on
	root@am64b_sdk11:~# ethtool -S eth1 | grep drop | grep -v 0
	 ale_drop: 21
	 rx_port_mask_drop: 21
	root@am64b_sdk11:~# ethtool -S eth1 | grep drop | grep -v 0
	 ale_drop: 21
	 rx_port_mask_drop: 21

Apart from SK-AM64B with latest SDK i see this issue on our hardware as well.

Hope this is enough for you to investigate multicast in general, let me know if you need any other information.

Regards,

-Dipal

P.S. The instructions to check mutlicast traffic were taken from gist.github.com/.../2597c23c68f21d938779aa92683d30b2.

Hi Dipal,

Thank you very much for sharing detailed steps on how to reproduce the issue with a simple multicast ping.

Fullscreen

ping -i enp8s0 224.10.10.10
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
ping -i enp8s0  224.10.10.10

I'm actually running in an issue with the above step where I'm unable to ping from my host PC to my SK-AM64B EVM as a test. I noticed that the "-i" option for ping is actually specifying the interval of seconds between each packet so I changed it to "-I" which specifies the interface name. Even after that, the ping hangs for me. See below for details:

Test setup:

SK-AM64B eth1 <--> Ethernet switch <---> enp3s0 Host Ubuntu PC

SK-AM64B eth0 <--> (another device since I do not have another interface on my Host Ubuntu PC - purpose is just to get the link status to be connected)

Even without the Ethernet switch connection, this step seems to fail. I checked that a ping from the host to the SK-AM64B works fine when using the non-multicast IP address that has been assigned to the eth1 port. Is there any step I'm missing that enabled your setup to work for this step?

Another question I have: does your eth0 to enp6s0 connection have an IP address on each interface or is it just a link connection?

Hi Daolin,

It will not work with Ethernet Switch (unless we enable multicast switching on it), so I suggest you check with direct connection.

Daolin Qiu said:

I tested with and without ip address on eth0 link. This does not matter.

Did you enable ICMP echo for broadcasts as given below?

sysctl -w net.ipv4.icmp_echo_ignore_broadcasts=0

I believe most likely this will be the reason.

Edit: I cross checked the ping argument it is indeed capital "-I", and ping fails without this option specified. Here is the log from my device (note that the response is still unicast from the unicast ip).

Yep, as you can see from the log I shared in my previous response, I did ensure the ICMP echo was enabled.

One thing I'm suspecting in relation to this multicast issue you are observing is simply the test topology you are using. While not directly related, when both Ethernet ports in Dual-MAC mode on the DUT (device under test) get connected directly to another device's two Ethernet ports, and the IP addresses of both ports on the DUT are configured for the same subnet, there would be issues in being able to ping between the two devices. This is related to the ARP packet being a broadcast packet causing, in some cases, finding the MAC address for the wrong ethernet interface. In this case, since the ARP broadcast would return the wrong MAC address, every ping reply would have the incorrect destination MAC address leading to lost ping packets.

For this reason, we recommend not connecting the devices like you have show in this block diagram. Instead, could you try testing this multicast case by using a different device connected to eth0 and eth1 of the AM64x device? For example, keep the Ubuntu PC connected to eth0 and send the mutlicast packets from PC to the AM64x device, and for eth1, connect to another known working PC or EVM, ensuring no IP address is configured.

Hi,

The multicast and the PTP issue was originally observed on the topology you suggested, this is just my test setup. Even in case of PTP we tried it on both topologies and it fails on all of them. We already tested PTP as reported sometime ago.

1. We tested this in two topologies as given below (Blue box is the Device in test), all logs in this thread are based on topo 2.

Topo 1:

Topo 2:

Nevertheless I will share the fresh logs with AM64-SK running latest SDK using Topo1.

Thanks for the reminder about the two different topologies. My main worry was that the topology 2 would be causing the issues as I described in my previous response. My question was if this multicast specific test (not the PTP test as you have done before) can be tested on topology 1 to isolate any potential issues related to topology 2.

Hi Daolin,

I have tested everything again and i can reproduce the issue consistently with SK-AM64B running latest SDK. I made a screencast of multicast ping to show how the devices interact when the issue is observed.

Let me know if you need any further information.

Edit 1: I made an interesting observation:

When the Multicast ping is working

1. If I physically disconnect and reconnect eth1 the ping resumes

2. If I physically disconnect and reconnect eth0 the ping stops and remains stopped.

Edit 2: Also I have tested everything swapping eth0 to eth1 and the behavior are same.

Hi Dipal,

Update: I was finally able to recreate the same multicast specific issue (issue was the device I had connected to eth1 on SK-AM62B was not on the same IP address subnet, this had to be configured statically)

While trying to debug further into the problem, I noticed that by also adding eth0 on SK-AM62B to join the same multicast group (ip addr add 224.10.10.10/24 dev eth0 autojoin), ping from device connected to eth1 on SK-AM62B did not fail.

I'm still trying to understand if getting multicast packet reception to work, does all linked up interfaces on the receiving device (in this case SK-AM64B) need to join the multicast group being used? If that is the case, perhaps the requirement is to ensure all linked up interfaces need to join the multicast group.

If that is not the case, another thing to note is that right at link of an interface, even if no IP address has been configured, there will be Ethernet traffic passed through. For example, the linked up eth0 interface in this test case, no IP address is configured but there is already active traffic initiated in an attempt to acquire an IP address. This can be seen by the nonzero rx_good_frames from ethtool -S eth0 upon simply link up. Perhaps this would a reason why the multicast ping would stop.

Daolin Qiu said:
I tested it out and see similar results to your log. For the ethtool drop counters, I notice these increment as long as there is a link up event, even if PTP was not running. Below is some information I could find on portmask drop and ale drop from the AM64x TRM. I don't think these are a PTP specific issue.

Daolin Qiu said:

As for the ale_drop and rx_port_mask_drop, as indicated by these snippets of the TRM I shared several responses back, they would increment when the packet destination address doesn't match the source address and number of packets that was dropped by ALE due to not being sent to any destination port, respectively. One thing to note, is that even if multicast ping wasn't being tested, and simply linking up an interface with no IP address configured on the same subnet as the connected interface, these counters would increment as well. For example, simple connection of eth1 SK-AM62B with enp8s0 on your setup, when these interfaces have no IP address configured, you would see these counters increment. As soon as IP address is configured, the counters would stop incrementing. At least this was the behavior I observed on my setup.

Below is a breakdown of the steps I took to recreate the issue

Test topology: "Host" eth0 <keep connected> eth1 SK-AM64B eth0 <keep disconnected> eth0 "Another known working device"
1. SK-AM64B is the DUT
2. "Host" can be any known working device NOT connected to the internet and NOT running a DHCP server
  1. I used a TMDS64EVM that I had handy
3. "Another known working device" can be any known working device NOT connected to the internet and NOT running a DHCP server and NOT the same device as "Host"
  1. I used a different TMDS64EVM that I had handy
Set static IP address on "Host" eth0
1. ip addr add 192.168.1.25/24 dev eth0
Start ping to multicast address on "Host" eth0
1. ping -I enp3s0 224.10.10.10
Set static IP address on DUT eth1
1. ip addr add 192.168.1.20/24 dev eth1
Join multicast address on DUT eth1
1. ip addr add 224.10.10.10/24 dev eth1 autojoin
Disable ignore broadcasts on DUT
1. sysctl -w net.ipv4.icmp_echo_ignore_broadcasts=0
Immediately after step 6, the "Host" should show ping packets sent through (multicast working)
1. You must ensure the "Host" eth0 has an IP address on same subnet as DUT eth1
Link up eth0 between DUT and "Another known working device" (either connect the cable or use ip link set dev eth0 up)
Observe that ping on "Host" stops and see that ale_drop and rx_port_mask_drop counters from ethtool -S eth1 on DUT increment

Is it not possible for you to simply also add eth0 to the same multicast group to ensure multicast works (and eventually PTP works)?

Thanks for the update, its good to know that you were able to recreate the issue.

Daolin Qiu said:

We have tried this already (for both PTP and normal Multicast).

Normal Multicast See Step 4:

Dipal Zambare said:
The resolution remains same, one of the following steps can resume the ping responses

Enable multicast "ip link set dev eth1 multicast on"

Force link up again (even though it is already up) "ip link set dev eth1 up"

Enable promiscus mode: "ip link set dev eth1 multicast on"

Configure static group membership (needed on both eth0 and eth1) "ip maddr add 01:00:5e:0a:0a:0a dev eth0" and "ip maddr add 01:00:5e:0a:0a:0a dev eth1"

PTP, see "I still need to configure it for both interfaces even though i am running PTP on one interface only"

I feel there is still something missing / can be improved on how this is handled by the TI drivers.

For PTP case we may still be able to configure the static group on both interfaces, but for normal multicast applications it wont' be feasible as both ports may want to subscribe to different groups.

Thanks for clarifying this. I've went ahead and filed a bug on the normal multicast issue since I was able to reproduce it and it appears that the issue is more likely a bug rather than a use-case issue. Our software developer who will be working on this is out of office this coming week so I anticipate there will be a delay in root causing the issue and providing a fix.

I'm currently looking into a way to dump out all the CPSW ALE entries to see if the ALE was registering the multicast address and port correctly. The fact that ale_drop and rx_port_mask_drop counters increment indicates that the multicast (destination) address was not found for some reason.

Currently it looks like "ethtool -d <interface name>" is a way to dump the CPSW registers including the ALE registers but seem to dump all the ALE entries.

Hi Daolin,

Thanks for the update, feel free to get back if you need any more Information.

Just to clarify further on normal multicast use case, generally the application is written by the customers. The multicast groups to join and the associated interfaces are decided by the application developer. The same application can be used on multiple devices, so it wont be possible to modify the application to subscribe to the same groups on all interfaces. Furthermore the applications do want to subscribe to different groups on different interfaces.

Update:

I was able to manually read a given ALE entry using devmem2 and the CPSW_ALE_TBLCTL (address 0x0803E020), CPSW_ALE_TBLW2 (address 0x0803E032), CPSW_ALE_TBLW1 (address 0x0803E038), CPSW_ALE_TBLW0 (address 0x0803E03C) registers. You can read more about these registers in the AM64x TRM.

By examining these registers before and after the link status changes on the "other" port, I noticed that the ALE entry for the multicast address changes from entry type "address entry" to a "free entry" (you can find more information about the entry types in the AM64x TRM). However, the root cause for this change in ALE entry type still needs to be tracked down, and I would need work with our software developer to do so. As I mentioned, the developer is out of office this week so there will be a delay in finding a fix.

Hi Dipal,

Here is what our developer found:

There is a bug or it might be an expected behaviour (yet to decide) in CPSW driver, since ALE table is a common resources for all the interfaces (both eth0 and eth1 in this case), whenever we bring down other interfaces it flushes out the multicast entries for other interfaces too which is not correct and that's why we are seeing this issue while working with PTP or normal multicast traffic.

Workaround for now:

Delete the multicast entry: ip addr del 224.10.10.10/24 dev eth1 autojoin and add it again: ip addr add 224.10.10.10/24 dev eth1 autojoin will resolve the issue, for PTP we need to synchronize the clocks again.

We'll update when/if we find a fix for this (still need to determine internally if this is a bug or expected behavior based on our ALE table design).

This is minimal example to reproduce the issue so we know the group address.

Unfortunately I don't think this is possible in real use case as the groups to join are decided by the end user applications, at a system level we can't configure them statically as each application will need to join different groups or even same application can join different groups at different times.

It can work for PTP as we know the addresses we are going to use.
