The value of aluPtpClockProfile specifies the conformance of the PTP system to either the default IEEE 1588-2008 behavior, or one of the ITU-T profiles. When aluPtpClockProfile is modified, several other objects are changed to the corresponding default value for the new profile. The following objects are affected: aluPtpClockDomain aluPtpClockUseNodeTime aluPtpClockAdminFreqSource aluPtpClockPriority1 aluPtpPortDSLogAnnoInterval aluPtpPortDSLogSyncInterval The new values for aluPtpClockUseNodeTime and aluPtpClockAdminFreqSource also depend on the values of aluPtpClockType and aluPtpClockSlaveOnly. This object can not be modified if aluPtpClockType is set to 'endToEndTransparent (3)'. When the aluPtpClockType is set to 'endToEndTransparent (3)' aluPtpClockProfile is 'unknown (0)'. This object can only be modified if aluPtpClockAdminState is set to 'outOfService (3)', otherwise an 'inconsistentValue' error is returned.
