## DESCRIPTION



           **dpauxmon** is an extcap tool that can capture DisplayPort AUX
           channel data from linux kernel drivers using the generic netlink
           interface.
    
           Supported interfaces:
    
            1. dpauxmon
    


## OPTIONS



           --help
               Print program arguments.
    
           --version
               Print program version.
    
           --extcap-interfaces
               List available interfaces.
    
           --extcap-interface=<interface>
               Use specified interfaces.
    
           --extcap-dlts
               List DLTs of specified interface.
    
           --extcap-config
               List configuration options of specified interface.
    
           --capture
               Start capturing from specified interface and save it in place
               specified by --fifo.
    
           --fifo=<path to file or pipe>
               Save captured packet to file or send it through pipe.
    
           --interface_idt=<interface id>
               The interface for capture.
    


## EXAMPLES



           To see program arguments:
    
               dpauxmon --help
    
           To see program version:
    
               dpauxmon --version
    
           To see interfaces:
    
               dpauxmon --extcap-interfaces
    
           Only one interface (dpauxmon) is supported.
    
           **Example output**
    
               interface {value=dpauxmon}{display=DisplayPort AUX channel capture}
    
           To see interface DLTs:
    
               dpauxmon --extcap-interface=dpauxmon --extcap-dlts
    
           **Example output**
    
               dlt {number=275}{name=dpauxmon}{display=DisplayPort AUX channel monitor DLT}
    
           To see interface configuration options:
    
               dpauxmon --extcap-interface=dpauxmon --extcap-config
    
           **Example output**
    
               dpauxmon --extcap-interface=dpauxmon --extcap-config
               arg {number=0}{call=--interface_id}{display=Interface Id}
                   {type=unsigned}{tooltip=The Interface Id}
                   {required=true}
    
           To capture:
    
               dpauxmon --extcap-interface=dpauxmon --fifo=/tmp/dpauxmon.pcap --capture --interface_id 0
