How do I get past "SFP Validation Failed" on a SFP-GE-T transceiver on a Nexus 5548UP?

  • 772

I inserted a SFP-GE-T (Gigabit RJ-45) transceiver in my Nexus 5548UP and I got "access down" "SFP Validation Failed" in show interface.

According to the Cisco Gigabit Ethernet Transceivers Compability Matrix the SFP-GE-T is compatible with the 5548UP.

    Configure the port as speed 1000 before inserting the SFP-GE-T transceiver.

    If you have the transceiver inserted already, remove it and then set speed 1000 on the port. Upon re-insertion the SFP should come up :)
