No link between 7206 and 15454

We are having trouble connecting a 7206 to a Cerent 454 over mutlimode fibe between WS-5484 SX GBIC's on the devices.

The sh int g0/3 on the 7206 shows line up and protocol down. Sh contr 0/3 shows the link down with no carrier. Even with the fiber pulled, the "sh int" command shows the line up.

Any insight into why the show int command appears wrong, and we can't get the link up?

Thanks!

The issue is due to the encapsulation mismatch problems on the two ends or the issue may be due to the keepalive mismatch.

Check the show running configuration for the keep alives configured on the interface.
