error on the trunk link

[Mohd Khairul Nizam]

why do i receive a lot of error on the trunk interface ? 

[chrihussey]

Either a bad SFP or fiber would be the logical assumptions.

Appears to be in the SWMYCJNEO-02 transmit to the SLMYCJNEO-02 receive direction. Check the light levels on either side with the "sh int Gx/x/x transceiver detail" if available.

1- Replace fiber jumpers on one side then the next.

2- Replace the SFP on the SWMYCJNEO-02 side.

3- Replace the SFP on the SLMYCJNEO-02 side.

4- Test the infrastructure fibers between switches and / or move to a new pair.

Hope this helps

meaning it always layer 1 issue, nothing to do with configuration itself

will it effect any slowness or connectivity issues?

[chrihussey]

It's more than likely a physical issue or bad SFP. That would be the first thing to look at. Yet anything is possible. If you want you can post the interface configurations on both sides.

i have post the configuration on both end on the 1st posting

Nothing out of the ordinary there. Check the fiber and SFPs as originally stated.

Yup, i have a swap a new SFP unit and no more error.
Thanks.
