Configuring the correction date of the UTC

This task allows you to adjust the UTC at the last minute (23:59) of the specified date.
To configure the correction date of the UTC:

Step Command

Remarks

1.

Enter system view.

system-view

N/A

2.

Configure the correction date
of the UTC.

ptp utc { leap59-date |
leap61-date } date

By default, the correction date of
the UTC is not configured.
This command takes effect only on

the GM.

Configuring the parameters of the Bits clock

Clock nodes in a PTP domain exchange announce messages through BMC to elect a GM. They compare

the parameters in the announce messages in the following sequence: priority 1, time class, time accuracy,
and priority 2. If all these parameters are the same, the clock node with a smaller port ID (consisting of

clock number and port number) wins.
To configure the clock parameters

Step Command

Remarks

1.

Enter system view.

system-view

N/A

2.

Configure priority 1 of the
clock.

ptp priority clock-source { bits1 |
bits2 | local } priority1 pri1-value

Optional.
The default is 128.

3.

Configure the parameters of

the Bits clock.

ptp clock-source { bits1 | bits2 }
{ accuracy acc-value | class
class-value | time-source ts-value }

By default, the time accuracy is
254, the time class is 248, and the

attribute value is 160 for the Bits

clock.

4.

Configure the time accuracy
of the Bits clock.

ptp clock-source { bits1 | bits2 }
accuracy acc-value

Optional.
The default is 254.

5.

Configure priority 2 of the
clock.

ptp priority clock-source { bits1 |
bits2 | local } priority2 pri2-value

Optional.
The default is 128.

6.

Configure the attribute value

of the Bits clock.

ptp clock-source { bits1 | bits2 }
time-source ts-value

Optional.
The default is 160.

Configuring a priority of the clock

Step Command

2.

Configure priority 1 of the
clock.

ptp priority clock-source { bits1 |
bits2 | local } { priority1 pri1-value

| priority2 pri2-value }

By default:
