By default, two-step mode is used.
Specifying a delay measurement mechanism for a BC or an
OC
PTP defines two transmission delay measurement mechanisms: Request_Response and Peer Delay. Ports
on the same link must share the same delay measurement mechanism. Otherwise, they cannot
communicate with one another.
BCs and OCs do not have a default delay measurement mechanism. You must specify a delay
measurement mechanism for them.
The delay measurement mechanism is Request_Response for E2ETCs and E2ETC+OCs and Peer Delay
for P2PTCs and P2PTC+OCs. You cannot change these default settings.
This task is applicable only to BCs and OCs.
If the PTP standard is IEEE 802.1AS, only Peer Delay mode is supported.

By default, the delay measurement
mechanism might vary depending
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 feature allows you to
configure one of the ports as an OC. This task is applicable only to E2ETC+OCs and P2PTC+OCs.
When a TC+OC is synchronizing time to a downstream clock node through a TC, do not enable an OC
to synchronize with the downstream clock node. Otherwise, time synchronization might be affected.
