  1. Version number (if the issue is upgrade related, specify which version was installed before as well); : ROS 7.0beta2
  2. Router’s model; : RB4011iGS+
  3. Steps to reproduce the issue :
  4. Bridge a PPPOE client into a Huawei EchoLife EG8245H5 modem/ONT/GPON
  5. Wait for couple of minutes/hours, ether10 will flap/disconnect by itself
  6. Configuration export (use ‘/export hide-sensitive’ command);

  1. Any additional information that would help troubleshoot the issue (screenshots, debug logs, etc.).

What i have done on my side is changing the UTP Cat6 cable to brand new cable & connector, the ether10/port flapping changing from every 20 Minutes into hours.
From past testing, this issue also happened with 6.45.6 or 6.46beta55

2

I have S+RJ10 attached into SFP+ port, before my power adapter is only 24 V 1.5 Ampere, after changing the power Adapter into 24 V 2.5 Ampere, the ether10 link is stable, now the link is up for more than 1d 06:14:00.

But the uptime only achievable by using ROS 6.45.6, using ROS 7.0beta3 is stuck with mentioned port flapping above, even it’s on hours or minutes for port flapping to happened.

Still not stable in v7.0beta5!, causing PPPOE-Client to disconnecting frequently, especially in high traffic.
