Troubleshooting steps taken:
1.User has another device with the matching hardware as well as software and SFP is working fine on another router
2.moved working sfp to this router, it stops working on this device
3.cable has been swapped.
4.changed the remote end to a different port and port still not coming up
5.default interface on both ends. still no go.
6.removed the vrf configuration and tried again. no go
7.Asked the user to connect the devices back to back. no go
8.verified that the code is compatible with the SFP - GLC-TE.
9.checked the duplex and speed settings, which are configured fine.
10.Replaced SFP on the port, still facing the same issue
11. Device has been RMAed and still the same issue persists.
