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

2.
Configure priority 1 of the
clock.
ptp
priority
clock-source
{
bits1
|
bits2
|
local
}
priority1
pri1-value
Optional.
The default is 128.
3.

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

}
By default, the time accuracy is
254, the time class is 248, and the
attribute value is 160 for the BITS
clock.
