DESCRIPTIONpmc 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.
