Thanks. The other side is showing no LINEPROTODOWN at all!

Hello,
Is it a fiber or a copper port? Is it possible to test the connection using a proper testing equipment? Also, if you connect the link into a different port, does that port behave in the same way?
I also recommend checking the interface counters on both sides of the link to see if there are any transmission errors that would suggest a problem with the medium.
Best regards,
Peter

Hi!
Thanks!
Its fiber.
Actually i see not CRC Errors. Only Symbol errors every now and then. I will try to connect them to a different port.
Actually i had the same problems with another port i moved from 2/0/6 to 2/0/8
whis was fine and AFTER that the problems startet with the other 2 ports 2/0/1 2/0/2
:-(

You my have a cross fibre - try swapping over the connections

This means swapping the fibres?
Is this some kind of Cross Talk?
