We have changed cables, switch but the behaviours occur.
All ideas are welcome.
Best regards.

Hi Friend,
Can you confirm what is connected to fa0/29,34 and 38 interfaces? Only these interfaces flap or any other interfaces also?
Can you also update "sh run interface fa0/29" from your switch?
Regards,
Ankur

Hello,
Thank you for you answer.
It takes on random interfaces.
We have changed the switch and behaviours occur again.
I have upgraded the version to the last.
On the older switch, it affects the giga interface :
Oct 10 06:14:40.498: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/1, changed state to down Oct 10 06:14:43.806: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/1, changed state to up
This interface is connected to another switch (backbone switch !)
The show run for this interface is :
interface FastEthernet0/29
switchport access vlan 5
switchport mode access
spanning-tree portfast
spanning-tree bpduguard enable
!
Thank you
