Function
Sets the adaptive clocking configuration
to the default settings.
Specifies the time period during initial
start of adaptive clocking during which
packet samples that are experiencing
the least delay through the network are
collected. These samples are used for
aggressive state calculations.
Specifies the time period during normal
adaptive clocking during which packet
samples that are experiencing the least
delay through the network are collected.
These samples are used for maintenance
state calculations.
Specifies the number of packets per
minute, which, when reached, causes the
adaptive clocking algorithm to change
from aggressive state to maintenance
state. Lower values result in longer
switchover times with a clock value
closer to the remote clock.
Specifies how quickly the clocking
corrects to the buffer set point while in
maintenance state.
Specifies a cap for frequency
acceleration, which constrains the
frequency adjustments to the adaptive
clock.
Specifies a cap for frequency velocity,
which constrains the frequency velocity
of the adaptive clock.
Specifies the buffer error rate required
to change the adaptive clocking
algorithm state from maintenance to
aggressive.
