NAME

       dcbd - Data Center Bridging capabilities exchange daemon

SYNOPSIS

       dcbd [-h] [-v] [-d] [-f filename]

DESCRIPTION

       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
              <http://download.intel.com/technology/eedc/dcb_cep_spec.pdf>

       and here:

       version 2
              <http://www.ieee802.org/1/files/public/docs2008/az-wadekar-dcbx-capability-exchange-discovery-
              protocol-1108-v1.01.pdf>

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

OPTIONS

       dcbd has the following command line options:

       -h     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.

       -d     run dcbd as a daemon

       -v     show dcbd version
