Do you see packets input increasing? If you have LDP adj over that interface can be a cosmetic issue (sounds strange, but...) That interface is in Half Duplex, i would fix forcing it too.

[sravan2211]

Yes,I can see the packets increasing on input and output of the interface of the secondary link.

The primary having the Full duplex and the secondary having the half-duplex. - will this need to be changed? please advice.

Hi,

Auto-nego is not working properly because of a fault cable or different vendors on each side, i would force it to 1000-full
