AM6422: AM6422 RSTP convergence test issue

DU WEI

Part Number: AM6422
Other Parts Discussed in Thread: TMDS64EVM

Hello,

Problem Description:RSTP convergence test does not meet the time requirement, with occasional convergence times exceeding 20s.

Test Description:The DUT is connected to switches to form a ring network, with RSTP enabled (using the userspace program mstpd 0.1.0). A PC uses ICMP to test RSTP convergence time.

Test Topology:PC - Switch 1 --(eth0) DUT1(eth1) -- (eth0)DUT2(eth1) -- (eth0)DUT3 (eth1)-- Switch 2 -- Switch 1

Test Steps and Observed Issues:

The DUT device is AM6422, with eth0 and eth1 configured in CPSW Switch mode.

When Switch 2 is powered on, DUT2 eth1 negotiates to the Alternate port state.

When Switch 2 is powered off, DUT2 eth1 negotiates to the Designated port state.

During the transition from Switch 2 power-on to power-off, the PC-to-DUT3 ping convergence time occasionally exceeds 20s.

Problem Investigation:
After Switch 2 is powered off, port mirroring enabled on Switch 1 captures a large number of ICMP request packets from the PC pinging DUT3. However, when DUT1 captures packets on eth0 using tcpdump, these ICMP requests are not observed.

Question:Is it possible that the ALE FDB is not flushed, causing ICMP requests to be dropped before the FDB entries age out?

Additional Information:
The mstpd 0.1.0 logs show that when an RSTP topology change occurs, it calls/sys/class/net/eth0/brport/flush to clear the bridge FDB. This ultimately calls am65_cpsw_switchdev_event_work with SWITCHDEV_FDB_DEL_TO_DEVICE. However, since the FDB entry is not added_by_user, the function returns directly without calling the final cpsw_ale_del_ucast.

Hello,

Thanks for providing the SDK version you are using.

Can you provide the specific commands/script you are using to setup RSTP?

What specific steps/script did you use to configure the DUT devices into CPSW switch mode?

DU WEI said:
The mstpd 0.1.0 logs show that when an RSTP topology change occurs, it calls/sys/class/net/eth0/brport/flush to clear the bridge FDB.

Can you share the contents of the mstpd logs?

Is it possible for you to do a sanity check on this perhaps by manually forcing an fdb flush?

# On each DUT, after Switch 2 power-off:

bridge fdb flush dev eth0 # Or your bridge interface (e.g., br0)

# Monitor if ping convergence improves immediately

Hello，

1. RSTP test script

PC run a script to continued ping all duts with 20 ms timout, during testing power on and off switch2 by a relay auto

2. CPSW switch mode script :

devlink dev param set platform/8000000.ethernet name switch_mode value true cmode runtime
interfac config script:
config device 'br_lan_device'
option name 'br-lan'
option type 'bridge'
list ifname 'eth0'
list ifname 'eth1'
option stp '1'

config interface 'lan'
option device 'br-lan'
option proto 'static'
option netmask 'xx'
option gateway 'xx'
option auto '1'
option ipaddr 'xx

3. DUT1 mstpd logs：

Jul 15 07:02:30 aug mstpd[581]: MSTP_OUT_flush_all_fids: br-lan:eth0:0 Flushing forwarding database
Jul 15 07:02:30 aug mstpd[581]: set_if_up: Port eth0 : up

4. bridge fdb flush command not support on my system, I just try to remove added_by_user check. It seems work, no exceeding 20s.

Hi Du Wei,

Apologies for the delayed response.

In order to verify if this is an issue with the driver and your workaround is the solution to the problem, I would need some time to reproduce the problem. To do this 1. can this issue be reproducible on TMDS64EVM? 2. is there a simpler topology than the one described that can reproduce the problem?

Hello Daolin,

Current TMDS64EVM is not available.

Please refer the following simple topology to reproduce this problem:

Ring Network link

SW - DUT1 - DUT 2 -- DUT3 - SW

RSTP topology

SW: root bridge

DUT 2(Alternate Port) -- DUT3: DUT2 eth1 port is Alternate Port connect to DUT3

Test step

1. ping DUT1 on DUT3, DUT1 eth 0 study DUT3 MAC, please refer picture 1.1

2. PC continuous ping DUT3 ， please refer picture 1.2 about the first 4 ping request

3. Unplug cable between DUT3 and SW, ping timeout about 30 times， refer 1.2

4. the DUT1 eth 1 study DUT3 MAC and ping restore， please refer picture 1.3

Log：

DUT1 ALE dump log and eth0 packets drop in ale dump and drop log.txt

Hi Du Wei,

DU WEI said:
SW: root bridge

Is the SW absolutely necessary? Is using just 3 DUT (for example TMDS64EVM) possible?

Also, maybe I missed this but was there a specific setup guide you were using from the TI SDK documentation to setup RSTP? Is there a specific user space application or setup script you are using to set up RSTP? It was mentioned a script was used for pinging but not clear any configuration needed to set up RSTP. I see you mentioned MSTPD logs which indicate some sort of daemon was used.

Hello Daolin,

We use openwrt uci tool to setup rstp. It equivalents to below commands. The mstpd veriosn is 0.1.0

ip link set dev eth0 down

ip link set dev eth1 down

sleep 1

ip link set dev eth0 up

ip link set dev eth1 up

sleep 2

devlink dev param set platform/8000000.ethernet name switch_mode value true cmode runtime

sleep 1

ip link add name br0 type bridge

sleep 1

ip link set dev eth0 master br0

ip link set dev eth1 master br0

ip link set dev br0 type bridge stp_state 2

ip link set dev br0 up

bridge vlan add dev br0 vid 1 self

bridge vlan add dev br0 vid 1 pvid untagged self

ip addr add 192.168.1.10/24 dev br0

sudo mstpd
sudo mstpctl setforcevers br0 rstp
sudo mstpctl addbridge br0

Hello Daolin,

SW is necessary. PC needs connect SW to ping DUTs.

I add some debug log to trace this issue. You can refer it.

BPDU TC occurs, mstpd will call flush. The debug log added in am65-cpsw-switchdev.c shows cpsw_ale_del_ucast is not called.

Thanks for sending the setup details. I will see what I can do to try and reproduce the problem.

If you don't hear from me by Wednesday next week, please kindly ping this thread.
