NAME
       pmc - PTP management client

SYNOPSIS
       pmc  [  -2 | -4 | -6 | -u ] [ -b boundary-hops ] [ -d domain-number ] [
       -i interface ] [ -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.

       Command help can be used to get a list of supported actions and manage‐
       ment 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  for
	      the  Unix	 Domain Socket transport and eth0 for the other trans‐
	      ports.

       -t transport-specific-field
	      Specify the transport specific field in sent messages as a hexa‐
	      decimal 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 send‐
	      ing GET actions with valid (but meaningless) TLV values.	There‐
	      fore  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.

MANAGEMENT IDS
       CURRENT_DATA_SET

       TIME_STATUS_NP

       NULL_MANAGEMENT
