Yes. Either change both to auto neogotiate or change the router to full duplex.

If you want to auto-negotiate then set the router interface to auto-negotiate ie. get rid of the "duplex half" statement.


I would do as Andrew suggested though - set both to 10full.

If you are setting the router interface to full duplex then do the same on the switch port.

Yes, traffic will be disrupted when you make the change. Probably best to do it out of hours.

It's more of quick interruption in traffic forwarding rather than full downtime. About 1 min per change should be more than enough.
