Correct Answer: ABC
Explanation/Reference:
Explanation:
The switch and CNA exchange capability information and configuration values. The Cisco Nexus devices support the following capabilities:
FCoE — If the CNA supports FCoE capability, the switch sends the IEEE 802.1p CoS value to be used with FCoE packets.
Priority Flow Control (PFC) — If the adapter supports PFC, the switch sends the IEEE 802.1p CoS values to be enabled with PFC.
Priority group type-length-value (TLV).
Ethernet logical link up and down signal.
FCoE logical link up and down signal for pre-FIP CNAs.
