My customer has a problem with flapping ports.
I 05/09/05 07:53:34 ports: port C6 is now off-line
I 05/09/05 07:53:37 ports: port C6 is now on-line
I 05/09/05 07:55:29 ports: port D3 is now off-line
I 05/09/05 07:55:31 ports: port D3 is now on-line
... and the same for almost all interfaces.
There are two switches connected together: 4000m and 4140gl.
Some vlans are configured.
The firmware is current on both.
All the links are configured for 100FDx on both sides.
LACP was disabled on all interfaces.
Does anybody have and idea what can cause that problem?
Thanks in advance for help !

Re: Flapping ports on 4000m and 4140gl switches
It occurs on all ports whether connected to Intel, Realtek and Broadcom NICs, so I'm pretty confident that it's a switch issue.
However, HP believes it to be driver problems or faulty cabling...
With all the different types of NICs and driver versions we have, I'm pretty sure that there would have been a couple of computers that didn't exhibit this problem, but there isn't...

Thanx for your reply.
Did you finally found the clue?
What was it?
Or do you still have the problem.
Do you think replacing the switch will solve the problem?
Best Regards,
Wojtek

Re: Flapping ports on 4000m and 4140gl switches
One cause was marginal jumpers. The patch cords were over-crimped, resulting in the contacts being too deep between the insulating spacers. This caused the spring pressure on the contacts to be diverted to the spacers instead. I have been replacing them whenever I encounter the toggles.
The second cause I attribute to drivers and power management settings. I had a few PCs toggling and when I updated the drives and turned off power management, they ceased to toggle.
