Ptp4l example This page documents the ptp4l program, which is the main PTP implementation in the LinuxPTP project. c; port. h; config. . static. logSyncInterval The mean time interval between Sync messages. Like ptp4l, phc2sys reports the time offset between PHC and System Clock, which determines if the clocks are synchronized. The default is 1 (2 seconds). Options required for use both by the service and on the command line should be specified in the /etc/ptp4l. The default is 0 (disabled). org Apr 28, 2025 · ptp4l - PTP Implementation Relevant source files. client_address The rms value reported by ptp4l once the slave has locked with the GM shows the root mean square of the time offset between the PHC and the GM clock. A shorter interval makes ptp4l react faster to the changes in the master-slave hierarchy. clock. See full list on events. It's specified as a power of two in seconds. The ptp4l program can be started from the command line or it can be started as a service. conf fi 4 days ago · For example, to reduce the output to every 1024 seconds, add the following line to the /etc/ptp4l. c; clock. c; config. conf file: summary_interval 10 An example of the ptp4l output, with summary_interval 6 , follows: This option allows ptp4l to work as a boundary clock using “just a bunch of devices” that are not synchronized to each other. h; ptp4l. When running as a service, options are specified in the /etc/sysconfig/ptp4l file. linuxfound. cmlds. If ptp4l consistently reports rms lower than 100 ns, the PHC is synchronized. . 8; ptp4l. c; Purpose and Scope. The interval should be the same in the whole domain. ptp4l implements the Precision Time Protocol (IEEE 1588) as a daemon that can function as an Ordinary Clock (OC), Boundary Clock (BC The mean time interval between Announce messages. For this mode, the collection of clocks must be synchronized by an external program, for example phc2sys(8) in automatic mode. cfg; port. h; configs/default. tvqd erydbv bpyb nium scdbn ryqjjy qmjfpf hcs ymqo rkuyg
