#
# Default configuration for sfptpd
#

#
# Generic Configuration
#

# Specify the PTP Synchronization Module. Can also be specified on the command
# line using the -m option.
sync_mode ptp

# Specify the interface to use. Can also be specified on the command line using
# the -i option.
interface eth0

# Specify whether messages are sent to the syslog, stderr or to a file. By default
# messages are sent to stderr.
message_log syslog

# Specify whether stats logging is enabled and whether stats are sent to stdout
# or to a file
stats_log off

# Configure sfptpd to run as a daemon
daemon

# whether to use a lock file to stop multiple simultaneous instances of the
# daemon. Enabled by default.
# lock off

# Specify how the clocks are controlled. By default clocks are stepped and
# slewed as necessary. Possible values are:
#    slew-and-step     Allow clock stepping as required
#    step-at-startup   Only allow the clock to be stepped at startup
#    no-step           Never step the clock
#    no-adjust         Do not make any adjustment to the clocks
#    step-forward      Only step the clock forward
# clock_control slew-and-step

# Specifies whether to use saved clock frequency corrections when disciplining
# clocks. Enabled by default.
# persistent_clock_correction on

# Specifies set of interfaces on which general receive packet timestamping should
# be enabled. Specify by interface name or MAC address or use * to enable receive
# timestamping on all interfaces that support it.
# timestamping_interfaces 00:0f:53:01:7b:fc eth33 *

# Specifies whether to disable timestamping on exit. This affects all interfaces
# specified with timestamping_interfaces as well as the interface selected for PTP.
# The default setting is on.
# timestamping_disable_on_exit on

# Specifies the trace level if the application has been built with trace enabled.
# Default is 0, no trace.
# trace_level 0

#
# PTP Configuration
#

# Specify PTP Slave mode
ptp_mode slave

# Specify PTP stats logging level. Generally not needed, recommend stats_log
# in preference.
# ptp_stats off

# Enable dump of each received PTP packet in detail - produces lots of output!
# ptp_pkt_dump

# Enable logging of PPS measurements and set the PPS propagtion delay
# ptp_pps_log
# pps_delay 0

# Specify threshold in nanoseconds for master-to-slave and slave-to-master
# delay measurements above which measurements are discarded.
# ptp_delay_discard_threshold 1000000

# TX and RX transmission latencies in nanoseconds - use to correct for network
# asymmetry.
ptp_tx_latency 0
ptp_rx_latency 0

# Specify the PTP network mode - conventional multicast or hybrid
ptp_network_mode hybrid

# TTL value. Default is 64.
# ptp_ttl 64

# Configures how PTP handles the UTC offset valid flag. The specification is
# ambigious in its description of the meaning of the UTC offset valid flag
# and this has resulted in varying different implementations. In most
# implementations, if the UTC offset valid flag is not set then the UTC offset
# is not used but in others, the UTC offset valid is an indcation that the
# master is completely confident that the UTC offset is correct. Various
# options are supported:
#    default  If UTCV is set use the UTC offset, otherwise do not use it
#    ignore   Do not used the UTCV flag - always apply the indicated UTC offset
#    prefer   Prefer GMs that have UTCV flag set above those that don't
#    require  Do not accept GMs that do not set UTCV
# ptp_utc_valid_handling default

# Use to modify the PTP domain in the range 0..255. Default is 0.
# ptp_domain 0

# Configure PTP management message support. Disabled by default. Possible
# values are:
#    disabled   Management messages disabled
#    read-only  Only requests to read information (GET) will be accepted
# ptp_mgmt_msgs disabled

# Access Control Lists
# This feature restricts the set of network addresses from which PTP will listen
# to timing and management messages. The control uses a permit and deny list
# and the option to specify the order in which the lists are evaluated. There are
# separate controls for timing and management messages.
# Each list should be a series of network address in the format a.b.c.d/x where
# a.b.c.d specifies the subnet and x the mask - to specify a single IP address
# a mask of 32 should be specified.
# When enabled, each time that a PTP message is received, the source IP address
# of the incoming message is matched against the permit and deny lists and the
# message is allowed or discarded accordingly.
# The network addresses in each list should be separated with spaces or commas e.g.
#       192.168.1.0/24 192.168.4.0/24 172.10.11.1/32 or
#       192.168.1.0/24,192.168.4.0/24,172.10.11.1/32
#
# ptp_timing_acl_permit 172.16.128.48/32 172.16.128.47/32
# ptp_timing_acl_deny 172.16.128.0/21
# ptp_timing_acl_order permit-deny
#
# ptp_mgmt_acl_permit 10.10.1.1/32 10.12.1.0/24
# ptp_mgmt_acl_deny 172.0.0.0/8
# ptp_mgmt_acl_order deny-permit

# The Announce receipt timeout in multiples of the announce interval.
# ptp_announce_timeout 6

# The Sync Packet receipt timeout in multiples of the sync packet interval.
# ptp_sync_pkt_timeout 6

# The Delay Request in interval in 2^number seconds. If specified for a
# PTP slave, this overrides the value communicated to the slave from the
# master.
# ptp_delayreq_interval 0

# The Delay Response receipt timeout 2^number seconds. Default is -2 (250ms).
# ptp_delayresp_timeout -2

# The maximum number of foreign master records a node is enable to store
# simultaneously.
# ptp_max_foreign_records 16

# Specifies whether to use hardware filtering of received PTP packets against
# the parent UUID. Default is on.
# ptp_uuid_filtering on

# Specifies whether to use hardware filtering of received PTP packets against
# the selected PTP domain number. Default is on.
# ptp_domain_filtering on

# Set PTPD debug message level. Defaults to 0 (off).
