3750X duplicate IP error

HI

I have just moved to the 3750X switch and have connected it to a 6509E. From the beginning I was having OSPF encryption errors, followed by flood warnings, LSA issue's, duplicate IP's which is baffling me. There are no IP's which match on either switch however the 3750X was continually power recycling causing the interfaces drop continually.

Even after disconnecting from the 6509 the 3750X continue to behave in the same manner. Could there be some issue with this switch?

3750X duplicate IP error

Hello!

1) Are you able to console to the switch? If so,what logs are you seeing? Is the POST getting completed.?

2) Have you tried connecting another power cable to switch or tried to boot it up from another power socket?

Regards.

Hi

Thanks for your quick reply.

I have tried another cable with the same affect, just keeps rebooting. I managed to console to the switch but within the logs I get the system restart message with all the mentioned errors followed by reboot and so on..

On the odd occassion the device remains active for 2-3 mins and then falls over again repeating all the errors.

Hi,

Now, if you totally isolate the 3750X, does it keep on rebooting? We need to make sure that the 3750x is OK at the hardware level.

Yes I isolated the 3750X and it continues to do the same thing.

This could be a hardware issue with the switch.

Please raise an RMA
