Cisco Nexus ERROR MSG - SFP Validation Failed

I came across the other day when I was bringing up a new connection on a Cisco 3548 Nexus.

"SFP validation failed"

This happens when the speed is set on an interface and the SFP does not support it. To fix it get into interface config mode and type.

 switchport host
 no speed
 no duplex
 no shut

Many more articles to come so ....
