Question: is down (sdp timeout/sfp mismatch)?
Answer: Symptom: SDP Timeout / SFP Mismatch error is seen on interface when trying to bring up FEX fabric ports in a port channel on N7K. This occurs only sometimes when FEX fabric port configurations are changed or re-applied to the ports on the N7K. After this bug appears the ports cannot be brought back to an "up" state.
