The aluPtpPortDSLogAnnoInterval represents the mean time interval
between successive Announce messages. The interval is specified as
the logarithm to the base 2 of the time interval in seconds. For
example the default value of 1 corresponds to an Announce interval of
2 seconds.
The default value of aluPtpPortDSLogAnnoInterval depends on the value
of aluPtpClockProfile. The defaults and the allowed ranges are
defined in the below table:
aluPtpClockProfile | default | range
---------------------------------------
'ituTelecomFreq (1)'| 1 | -3..4
'ieee1588-2008 (2)' | 1 | -3..4
'g8275dot1-2014 (3)'| -3 | -3..4
'g8275dot2-2016 (4)'| 1 | -3..4
For ordinary slave and boundary clocks utilizing unicast negotiations,
this is the rate at which a ptp-port will request Announce messages
from the remote PTP clock.
The aluPtpPortDSLogAnnoInterval it also determines how often the Best
Master Clock Algorithm (BMCA) is run. For example on an ordinary clocks
with the aluPtpPortDSLogAnnoInterval set to 3, the BMCA would be run
once every 8 seconds. On boundary clocks the ptp-port with the smallest
aluPtpPortDSLogAnnoInterval would be used to determine how often the
BMCA is run.
