Specifying A Delay Measurement Mechanism For A Bc Or An Oc; Configuring The Port Type For A Tc+Oc - H3C SR6600-X Configuration Manual

Step
1. Enter system view.
2. Enter Layer 3 Ethernet
interface view.
3. Configure the mode for
carrying timestamps.
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.
To specify a delay measurement mechanism for a BC or an OC:
Step
1. Enter system view.
2. Enter Layer 3 Ethernet
interface view.
3. Specify a delay measurement
mechanism for a BC or an
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 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.
To configure the port type for a TC+OC as OC:
Step
1. Enter system view.
2. Enter Layer 3 Ethernet
interface view.
