Context config>system>ptp
Description This command configures the PTP domain.
The no form of the command reverts to the default configuration. The default value is dependent upon
the configured profile, as detailed below.
Note some profiles may require a domain number in a restricted range. It is up to the operator to ensure
the value aligns with what is expected within the profile.
Domain cannot be changed unless PTP is shutdown. If the PTP profile is changed, the domain is
changed to the default domain for the new PTP profile.
Default 0 — profile ieee1588-2008
4 — profile g8265dot1-2010 or
24 — profile g8275dot1-2014
Parameters domain — The PTP domain.
Values 0 to 255 for ieee1588-2008
0 to 255 for g8265dot1-2010
24 to 43 for g8275dot1-2014

Context config>system>ptp
Description This command configures the announce message interval used for both unicast and multicast
messages.
For unicast messages, it defines the announce message interval that is requested during unicast
negotiation to any peer. This controls the announce message rate sent from remote peers to the local
node. It does not affect the announce message rate that may be sent from the local node to remote peers.
Remote peers may request an announce message rate anywhere within the acceptable grant range.
For multicast messages, used on PTP Ethernet ports, this configures the message interval used for
Announce messages transmitted by the local node.
This value also defines the interval between executions of the BMCA within the node.
The announce-interval cannot be changed unless the PTP is shut down.
Note: In order to minimize BMCA driven reconfigurations, the IEEE recommends that the announce-
interval should be consistent across the entire 1588 network.
Default 1 (1 packet every 2 seconds) for ieee1588-2008 or
