ntpDesiredAcc OBJECT-TYPE SYNTAX INTEGER (0..2147483647) MAX-ACCESS read-only STATUS current

DESCRIPTION

“The desired (worst case time) accuracy in microseconds that the time server will attempt to steer to. This variable is related to ntpEstError. Should ntpEstError be greater than ntpDesiredAcc, the NTP alarm condition will be set (ntpSysLeap will be equal to 3). Note: outgoing NTP packets will have their leap indicator field set to ntpSysLeap.”

::= { ntp 5 }

ntpEstErr OBJECT-TYPE

SYNTAX INTEGER (0..2147483647) MAX-ACCESS read-only STATUS current

DESCRIPTION

“The current estimated (time) error in microseconds of the time server. This variable is related to ntpEstError. Usually, this value is small and constant for a given type of time server. However, when primary synchronization is lost, this value will slowly increase with time as the time server’s oscillator flywheels away from true time. Should ntpEstError be greater than ntpDesiredAcc, the NTP alarm condition will be set (ntpSysLeap will be equal to 3).

Note: a primary time server’s outgoing NTP packets will have its leap indicator field set to ntpSysLeap.”

::= { ntp 6 }

ntpSysLeap OBJECT-TYPE SYNTAX INTEGER

{

noLeapWarningAndTimeIsSynchronized(0),

lastMinuteHas61SecondsAndTimeIsSynchronized (1),

lastMinuteHas59SecondsAndTimeIsSynchronized (2),

alarmConditionAndLossOfTimeSynchronization (3)

}

MAX-ACCESS read-only STATUS current

DESCRIPTION

“This is a status code indicating normal operation, a leap second to be inserted in the last minute of the current day, a leap second to be deleted in the last second of the day or an alarm condition indicating the loss of timing synchronization. Note: a primary time server’s outgoing NTP packet will have its leap indicator field set to ntpSysLeap.”
