6.4 DCBX commands
6.4.1 show lldp dcbx interface ethernet interface_number
The show lldp dcbx interface ethernet interface_number command is used to verify DCBX is
operational and in sync with the connected CNA. The local DCBx TLVs Transmitted field is ErPFi,
confirming ETS, PFC, and FCoE TLVs are transmitted to the CNA. (Refer to the table at the top of the
command output).
Note: TLV stands for type, length, and value. Groups of type, length, and value fields, transmitted in Link
Layer Discovery Protocol (LLDP) frames, are commonly referred to as TLVs.
The ETS TLV transmits the bandwidth allocation , the PFC TLV enables priority flow control, and the FCoE
TLV assigns the dot1p priority value to FCoE traffic.
