dcbd - Data Center Bridging capabilities exchange daemon  


dcbd [-h] [-v] [-d] [-f filename]  


Executes the Data Center Bridging (DCB) capabilities exchange protocol on DCB capable Ethernet interfaces in order to exchange DCB configuration with the peer device.

Major functions of dcbd include:
- retrieving and storing DCB configuration to a configuration file
- configuring the DCB settings of the network driver based on the operation of the DCB capabilities exchange protocol
- detecting and reacting to link up and link down events on network ports
- supporting the following DCB features: Priority Groups, Priority Flow Control, FCoE and FCoE Logical Link Status.
- providing an interface for client applications to query and configure DCB features. Events are also generated on the client interface when the operational state or configuration of a feature changes.

dcbd supports the versions of the DCB capabilities exchange protocol described here:

version 1

and here:

version 2

See dcbtool for information on how to configure which version of the protocol dcbd executes.



dcbd has the following command line options:
show usage information
-f filename
use the specified file as the configuration file instead of the default file: /etc/sysconfig/dcbd/dcbd.conf dcbd expects the directory of the configuration file to exist, but if the configuration file does not exist, then a default configuration file will be created.
run dcbd as a daemon
show dcbd version
