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.
