i have a cisco nexus 5000 and i connect to it a fex (model: N2K-C2232PP-10GE).
I have 3 ports in the fex with there error messege of "sfp validation failed". I saw in many sites that the soltuion is to pull out the sfp, then set the port's speed to 1000 and inerst back the sfp. I did it, and also shut/no shut the port, and check it with several sfp, and the error not change.
When i pulled out the sfp , the port not shows as empty (no messege that not sfp inside), and still there was a messege of validation failed. After put other sfp and pull it out again, the port shows as empty(but after inerst it back the error shows again). Also the ports are bliking in orange lights.
The sfp i use is FET-10G (cisco sfp).
Does anybody know what can be the problem?
Kindly make sure you have the below command configured on that interface::
"switchport mode fex-fabric"
