Hi,


I have an interface that generates CRCs and Errors,

This interface has the following configurations and is connected to an
RPM-PR (7200 router)

Cat-3524#sh run int FAstEthernet 0/2

interface FastEthernet0/2

end



The adjacent interface on the RPM has the following configurations :

MCE#sh run int FastEthernet 1/1

     0 babbles, 0 late collision, 0 deferred
     0 lost carrier, 0 no carrier
     0 output buffer failures, 0 output buffers swapped out

in my humble experience, i should try to 

1) have the same duplex on both, which i think i have.
2) change cable, also done

Whats my next step ?
