Описание (Description)

Data Center Bridging eXchange (DCBX) is a protocol used by DCB devices to exchange configuration information with directly connected peers. The Linux DCBX object is a 1-byte bitfield of flags that configure whether DCBX is implemented in the device or in the host, and which version of the protocol should be used. dcb dcbx is used to access the per-port Linux DCBX object.

There are two principal modes of operation: in host mode, DCBX protocol is implemented by the host LLDP agent, and the DCB interfaces are used to propagate the negotiate parameters to capable devices. In lld-managed mode, the configuration is handled by the device, and DCB interfaces are used for inspection of negotiated parameters, and can also be used to set initial parameters.

Параметры (Parameters)

When used with dcb dcbx set, the following keywords enable the
       corresponding configuration. The keywords that are not mentioned
       on the command line are considered disabled. When used with show,
       each enabled feature is shown by its corresponding keyword.

       host
       lld-managed
              The device is in the host mode of operation and,
              respectively, the lld-managed mode of operation, as
              described above. In principle these two keywords are
              mutually exclusive, but dcb dcbx allows setting both and
              lets the driver handle it as appropriate.

       cee
       ieee   The device supports CEE (Converged Enhanced Ethernet) and,
              respecively, IEEE version of the DCB specification.
              Typically only one of these will be set, but dcb dcbx does
              not mandate this.

       static indicates the engine supports static configuration. No
              actual negotiation is performed, negotiated parameters are
              always the initial configuration.

Примеры (Examples)

Put the DCB engine into the "host" mode of operation, and use
       IEEE-standardized DCB interfaces:

       # dcb dcbx set dev eth0 host ieee

       Show what was set:

       # dcb dcbx show dev eth0
       host ieee
