NAME

       pmc - PTP management client

SYNOPSIS

       pmc [ -2 | -4 | -6 | -u ] [ -b boundary-hops ] [ -d domain-number ] [ -i interface ] [ -s uds-address ] [
       -t transport-specific-field ] [ -v ] [ -z ] [ command ] ...

DESCRIPTION

       pmc  is  a  program which implements a PTP management client according to IEEE standard 1588. The program
       reads from the standard input or from the command line actions specified by name and management ID, sends
       them over the selected transport and prints any received replies. There are three actions supported:  GET
       retrieves the specified information, SET updates the specified information and CMD (or COMMAND) initiates
       the specified event.

       By default the management commands are addressed to all ports. The TARGET command can be used to select a
       particular clock and port for the subsequent messages.

       Command help can be used to get a list of supported actions and management IDs.

OPTIONS

       -2     Select the IEEE 802.3 network transport.

       -4     Select the UDP IPv4 network transport. This is the default transport.

       -6     Select the UDP IPv6 network transport.

       -u     Select the Unix Domain Socket transport.

       -b boundary-hops
              Specify the boundary hops value in sent messages. The default is 1.

       -d domain-number
              Specify the domain number in sent messages. The default is 0.

       -i interface
              Specify  the  network  interface.  The  default  is  /var/run/pmc.$pid  for the Unix Domain Socket
              transport and eth0 for the other transports.

       -s uds-address
              Specifies the address of the server's UNIX domain socket.  The default is /var/run/ptp4l.

       -t transport-specific-field
              Specify the transport specific field in sent messages as a hexadecimal  number.   The  default  is
              0x0.

       -h     Display a help message.

       -v     Prints the software version and exits.

       -z     The  official  interpretation  of  the  1588 standard mandates sending GET actions with valid (but
              meaningless) TLV values. Therefore the pmc program  normally  sends  GET  requests  with  properly
              formed  TLV  values.  This  option  enables  the  legacy  option of sending zero length TLV values
              instead.
