PTP Configuration
To configure PTP follow these instructions. Figure C.36 illustrates the PTP configuration page.
Choices for the Delay Mechanism include either P2P (Peer to Peer) or E2E (End to End). Protocol
choices include UDP IPv4, UDP IPv6 or Layer 2. Figure C.36 shows the Advanced settings, which
can be hidden using the Hide Advanced button.

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).
