Hi All,
I have issues with Nexus 5548 ports 1000Gb ports. They go down after sometime with the error " Link not connected " while the links are connected. When i move the connections to other ports they work but after a while the go down again with the same error. I can confirm that is currently down was working and its currently connected. Has anyone seen the error before?
Kindly see the output from the interface thats currently down below:
VNX_NEXUS# sho interface eth1/11

You've got a line fault.

Hi Leo,
What confuses me is that the connection was working. I used the correct cable and the port type as well. How do i resolve this?

Describe this link. Fibre/Copper?
What kind of fibre? SR/LH?
