Port bounces up and down once after reboot: X670G2-48x-4q

Port bounces up and down once after reboot: X670G2-48x-4q

After reboot of the switch some port are bouncing up and down one time. We don't see any reason for this and it's causing traffic loss for us.

11/16/2016 13:19:22.61 Port 49 link UP at speed 40 Gbps and full-duplex
11/16/2016 13:19:20.21 Port 10 link UP at speed 10 Gbps and full-duplex
11/16/2016 13:19:20.21 Port 9 link UP at speed 10 Gbps and full-duplex
11/16/2016 13:19:20.58 Port 9 link down - Local fault
11/16/2016 13:19:21.49 Port 10 link down - Local fault
11/16/2016 13:19:24.75 Port 10 link UP at speed 10 Gbps and full-duplex
11/16/2016 13:19:24.75 Port 9 link UP at speed 10 Gbps and full-duplex
11/16/2016 13:19:33.11 Port 49 link down - Local fault
11/16/2016 13:19:35.93 Port 49 link UP at speed 40 Gbps and full-duplex

Is this some known behaviour or do anyone have a idea what could cause such behaviour.

If you wonder we are running test activitys within mobile networks and this is part of some testcases.

Hi
I have the same problem again, the bouncing ports are:
1.isc ports connected to peer switch;
2.the ports connected to HP GEN7 Host (EXSI).

(No STP running.)

Is it maybe because the extreme switch port is 10G FULL DUPLEX, and EXSI side is AUTO-Negotiation?

Thanks.

Have you been able to resolve this problem?
