Hi everyone.

I swapped X2 transciever from "faulty" TenGigabitEthernet4/5 X2 socket to TenGigabitEthernet4/3:

As you can see the errors are magically disappeared.

So, I assum that TenGigabitEthernet4/5 X2 hole is defective. How can I confirm that using CLI?

Hi,

You should see link flaps or any errors related to te4/5 or module 4 under "show log" output. You could also check diagnostics of the module using :

"show diagnostics result module 4" and "show diagnostics events"

Regards,

you can check the status of the port asic to see if you are dropping packets

Hi,

Please clear the counters once and see if they are incrementing again.

If they are incrementing:

1. Check logs to see if anything is wrong with the affected interface.

2. And is there any performance issue beacuse of these errors.

If not, then this could be a cosmetic bug.

Hope that helps.

Cheers

Sweta

P.S. Please rate the answer if it was useful.

Thanks guys,

Whole WS-X6708-10GE card was changed to a new one and all errors dissapered after this operation. Card with errors returned back to Cisco partner for testing. Waitng for.
