DCBx guidelines

DCBx is only supported on the 8325 switch series.

DCBx is disabled by default.

LLDP must be enabled on the interfaces supporting DCBx.

DCBx is only supported on physical interfaces and not on management or logical interfaces, similar to how LLDP behaves.

ArubaOS-CX supports only the IEEE 802.1Qaz 2011 version of DCBx with an OUI of 0x0080c2.

ArubaOS-CX advertises DCBx with 'willing bit' set to 0 in all TLVs. This tells the peer that the switch is not willing to change its configuration to match the peer's configuration.

When a peer switch does not support IEEE DCBx, a misconfiguration error will be displayed in the show dcbx interface output.
