OS10 supports DCBX versions CEE and IEEE2.5.
If ETS and PFC are enabled, DCBX advertises ETS configuration, ETS recommendation, and PFC configuration. When you
configure application-specific parameters such as FCoE or iSCSI to be advertised, DCBX advertises the respective
Application Priority TLVs.
A DCBX-enabled port operates only in a manual role. In this mode, the port operates only with user-configured settings and
does not autoconfigure with DCB settings that are received from a DCBX peer. When you enable DCBX, the port advertises
its PFC and ETS configurations to peer devices but does not accept external, or propagate internal, DCB configurations.
NOTE: OS10 does not support autoupstream and autodownstream DCBX port roles. Hence, DCBX-enabled port
autoconfiguration is not supported.
DCBX detects a misconfiguration on a peer device when DCB features are not compatibly configured with the local switch.
NOTE: Misconfiguration detection is feature-specific because some DCB features support asymmetric (nonidentical)
configurations.
Verify DCBX configuration
Verify the DCBX, PFC, and ETS configurations on an interface, using the appropriate commands.
