PTP Terms
• Domain – a collection of one or more PTP subdomains. A subdomain is a logical grouping
of 1588 clocks that synchronize to each other using the PTP protocol, but that are not
necessarily synchronized to PTP clocks in another PTP subdomain. Subdomains provide
a way of implementing disjoint sets of clocks, sharing a common network, but maintaining
independent synchronization within each set.
• Announce interval – specifies the time for sending announce messages. The range is from 0
to 4 seconds; the default is 2 seconds.
• Sync interval – the time for sending synchronization messages. The range is from -1 to 1
seconds; the default is 1 second.
• Delay request interval – specifies the time recommended to the member devices to send delay
request messages when the port is in the master state. The range is -1 second to 6 seconds.
The default is 5 (32 seconds).
