Dcbx Prerequisites And Restrictions; Dcbx Configuration Procedure - Dell Force10 S4810P Configuration Manual

DCBx Prerequisites and Restrictions

The following prerequisites and restrictions apply when you configure DCBx operation on a port:
• DCBx requires LLDP in both send (TX) and receive (RX) mode to be enabled on a port interface
(

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 (LLDF), and network interface virtualization
(NIV).

DCBx Configuration Procedure

To configure an S4810 or S4820Tfor DCBx operation in a data center network, you must:
1. Configure ToR- and FCF-facing interfaces as auto-upstream ports.
2. Configure server-facing interfaces as auto-downstream ports.
3. Configure a port to operate in a configuration-source role.
4. Configure ports to operate in a manual role.
To verify the DCBx configuration on a port, use the
Configure DCBx operation at the interface level on a switch or globally on the switch.
Prerequisite: DCBx requires LLDP to be enabled to advertise DCBx TLVs to peers. For more
