Are you positive you have the DLCI assignments the same as in the 3COM router you replaced?
What do 'show frame map' and 'show frame pvc' look like? Do you have any PVCs that are UNUSED/INACTIVE? On the remote side that is UP/DOWN, do you see any incoming packets at all or does it think the interface is up simply because DTR is high? What does show interface show on the remote side? Equal numbers of LMI enquiries sent compared to stats received? Thanks, John >>> "Bob Timmons" 1/17/02 10:35:42 AM >>> On S5/1 I get UP/UP. On S5/1.4, I get UP/UP on our side and UP/UP on the remote side. On S5/1.3 I get Down/Down on our side and Up/Down on their side. > What do you mean, specifically?
