Ethernet interfaces randomly resets

[jac_nor]

Hi,

I have an issue, I'm running PA-200 with PAN-OS ver. 6.0.12

I'm running Palo in Virtual Wire mode Eth1/1 is untrusted zone and Eth1/2 is trusted zone.

My problem is that from unknown reason the interfaces randomly just freeze (LEDs are going off) and after few seconds interfaces are back. But the problem the traffic in network is already interrupted.

The problem is that system log doesn't say much. You can see it Yourself.

Any ideas ??

Best Regards, Jacek

Have tested / swap the Ethernet cables?

Try other interfaces on the PA-200?  

Try other interface on the network device?

Try these one at a time and see if that helps.

Yes I did try other cables.

Also Yes different network devices were connected to those ports.

So the only thing I didn't tried is to make virtual wire on eth1/3 and eth1/4.

Probably I will try that, but also I plan to move to PAN-OS 6.1.x series.

try disabling link state pass through for a while to help make sure which interface is flapping, then try switching that interface to a different physical interface to see if it stays up
