DCBx Prerequisites and Restrictions
The following prerequisites and restrictions apply when you congure DCBx operation on a port:
• DCBx requires LLDP in both send (TX) and receive (RX) modes to be enabled on a port interface. If multiple DCBx peer ports are
detected on a local DCBx interface, LLDP is shut down.
• The CIN version of DCBx supports only PFC, ETS, and FCOE; it does not support iSCSI, backward congestion management
(BCN), logical link down (LLD), and network interface virtualization (NIV).
