SMU Install Questions:
----------------------
1- Console/error messages during SMU activation/deactivation?  Please specify the safe messages to ignore
PTP session with remote PTP server will flap, and the PTP servo will re-lock after ptp_ctrlr process restart.

RP/0/RP0/CPU0:Sep 20 14:31:38.724 UTC: ptp_ctrlr[1084]: %PLATFORM-PTP-6-SERVO_EVENTS : PTP Servo state transition from state FREERUN to state FREQ_LOCKED 
RP/0/RP0/CPU0:Sep 20 14:32:00.647 UTC: sdr_instmgr[1205]: %INSTALL-INSTMGR-2-OPERATION_SUCCESS : Install operation 6 finished successfully
RP/0/RP0/CPU0:Sep 20 14:34:58.748 UTC: ptp_ctrlr[1084]: %PLATFORM-PTP-6-SERVO_EVENTS : PTP Servo state transition from state FREQ_LOCKED to state PHASE_LOCKED 
RP/0/RP0/CPU0:Sep 20 14:35:01.295 UTC: ptp_ctrlr[1084]: %L2-PTP-6-CLOCK_CLASS_CHANGED : Advertised clock class changed. Old clock class: 165. New clock class: 6

2- Are there any side effects to this SMU that require workaround? (for example AAA SMU requiring exit out of current session and reconnecting after install).  If so what?
NA

SMU Caveats:
NA
