       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
       - 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:

       -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
