3.

Specify a delay measurement
mechanism for a BC or OC.

ptp delay-mechanism { e2e | p2p }

By default, the delay measurement
mechanism depends on the PTP

standard.

Configuring the port type for a TC+OC

All ports on a TC+OC (E2ETC+OC or P2PTC+OC) are TCs by default. This command allows you to

configure one of the ports as an OC. This task is applicable to E2ETC+OCs and P2PTC+OCs only.
When a TC+OC is synchronizing time to a downstream clock node through a TC, do not enable an OC
to synchronize time from the downstream clock node. Otherwise, time synchronization might be affected.
To configure the port type for a TC+OC as OC:

By default:

The interval is 2

1

seconds if the

PTP standard is IEEE 1588

Version 2.

The interval is 2

0

seconds if the

PTP standard is IEEE 802.1AS.

Specifying the number of announcement intervals before the
receiving node stops receiving announce messages

A master node periodically sends announce messages to the member nodes. If a member node does not
receive any announce message from the master node within the specified interval, it considers the master

node invalid.
