While trying to connect Nexus 2224TP to Nexus 56128 switch,
using 10G-SFP-SR instead of 10G FET due to distance issue, I got transceiver

To solve this error simply configure on the port mode

Thanks so much for posting this information. As it was working fine at 5k switch & it wasnt for another so I was assuming something wrong with the non working switch. Even support team was ready to replace the 5K switch but before I request for an RMA I got this informaiton & saved my lot of time :)
