Ethernet interface view.
3.
Specify a delay measurement
mechanism for a BC or OC.

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:
Step
1.
Enter system view.
2.
Enter Layer 2 Ethernet
interface view or Layer 3
Ethernet interface view.
3.
Configure the port type for a
TC+OC as OC.
