Configuring The Role Of A Ptp Port; Configuring The Mode For Carrying Timestamps - H3C SR6600-X Configuration Manual

Step
2. Configure the priority for the
specified clock for GM
election through BMC.

Configuring the role of a PTP port

Typically the master/member relationships are automatically specified through BMC. This task allows
you to manually configure the master/member relationships among clock nodes. The ptp force-state
command is available only after you configure the ptp active force-state command.
Follow these guidelines when you configure the role of a PTP port:
Only one subordinate port is allowed to be configured for a device.
•
• This task is also applicable to an OC that operates in slave-only mode.
To configure the PTP port role on an OC, BC, E2ETC+OC, or P2PTC+OC:
Step
1. Enter system view.
2. Enter Layer 3 Ethernet
interface view.
3. Configure the role of the PTP
port.
4. Quit interface view.
5. Activate the port role
configuration.

Configuring the mode for carrying timestamps

Timestamps can be carried in either of the following modes:
Single-step mode—In single-step mode, the Sync message in the Request_Response and Peer Delay
•
mechanisms, and the Pdelay_Resp message in the Peer Delay mechanism carry the sending time of
the messages.
• Two-step mode—In two-step mode, the Sync message in the Request_Response and Peer Delay
mechanisms, and the Pdelay_Resp message in the Peer Delay mechanism do not carry the sending
time of the messages. The sending time is carried in other messages.
To configure the mode for carrying timestamps for every clock node:
Command
ptp priority clock-source { local |
tod0 | tod1 } { priority1 pri1-value
| priority2 pri2-value }
Command
system-view
interface interface-type
interface-number
ptp force-state { master | passive |
slave }
quit
ptp active force-state
122
Remarks
By default:
•
If the PTP profile is IEEE 1588
version 2, the default value for
both priority 1 and priority 2 is
128.
•
If the PTP profile is IEEE
802.1AS, the default value is
246 for priority 1 and 248 for
priority 2.
