Hi guys,

On a specific switch with a specific NIC the port keeps going up and
down every couple seconds ( tried on 4 different ports), if I take the
comp to another switch it works perfect.

Any Idea what may cause this ?

Thanks,
Dan

Are the switch ports configured identical?

What is the switch model?
Can you post a 'show port' or 'show interface' output (depending if
switch is IOS or CatOS based)?

Can you tell what is the scurrent status of Switch port.
Is it in any VLAN or ??

There can be many reasons for switch port going up and down.

Hi,

I would check the Speed and the Duplex settings on the switch and the
desktop/servers.
