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
