ptp

The ptp command is used to manage SMPTE ST 2110 Precision Time Protocol parameters. PTP keeps all clocks in a given ST 2110 network in sync.

Note

SMPTE ST 2110 must be licensed on the encoder, and the encoder personality set to ST 2110.

Synopsis

ptp get [config]
ptp set [parameter=value]

Actions

Action	Description
get	Displays the PTP configuration information.
set	Configures the PTP settings. A series of one or more parameter=value pairs can be specified at once. See Parameters below.

Parameters

Parameter	Default	Description/Values
`domainnumber`	127	Specifies the domain number for each clock using PTP in the domain network. Values can be: 0-127
`announceinterval`	0.25	The interval of time (in seconds) between the dispatch of IEEE 1588-2008 Announce messages. Values can be: 0.125, 0.25, 0.5, 1, or, 2 secs
`announcereceipttimeout`	3	Specifies the number of announce receipts received before the function times out and announce messages stop being sent. Values can be: 2-10
`syncinterval`	0.125	The interval of time (in seconds) between the dispatch of IEEE 1588-2002 Sync messages. Values can be: 0.0078125, 0.015625, 0.03125, 0.0625, 0.125, 0.25, 0.5, 1, or, 2 secs
`delaymechanism`	automatic	Sets the type of delay mechanism used, either automatic, end-to-end, or peer-to-peer. Values can be: automatic, e2e, p2p

Examples

# ptp get

Returns the current ptp configuration:
