An Ethernet interface that shows the interface up but the line protocol down is frequently because of problems with connecting the interface. Is this interface connected to something? If so what is it connected to? Can you check and verify that the cable on each end is well and firmly connected? What happens if you disconnet and reconnecct both ends of the connection?
Are you using the correct type of cable (straight through or crossover)? What happens if you change to the other type of cable?
Perhaps there is a problem with the cable that you are connecting with. What happens if you replace this cable with another cable of the same type?
