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.
