DESCRIPTION

"The deprecated 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 (0..3)

MAX-ACCESS read-only

STATUS deprecated

DESCRIPTION

"This is a status code indicating normal operation, a leap second to

be inserted in the last minute of the deprecated 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."

::= { ntp 7 }

ntpSysHostMode OBJECT-TYPE

SYNTAX INTEGER (0..7)

MAX-ACCESS read-only

STATUS deprecated

DESCRIPTION

"The value of this variable indicates the mode that the host is

operating in. Note: this is the value of the time server's outgoing

NTP packet mode field."

::= { ntp 8 }

ntpSysStratum OBJECT-TYPE

SYNTAX INTEGER (1..255)

MAX-ACCESS read-only

STATUS deprecated

DESCRIPTION

"This is an integer that ranges from 1 to 255 indicating the stratum

level of the local clock. Note: a primary time server sets outgoing NTP

packets stratum field and ntpSysStratum to 1."

::= { ntp 9 }

ntpSysPoll OBJECT-TYPE

SYNTAX INTEGER (6..10)

MAX-ACCESS read-only

STATUS deprecated

DESCRIPTION

"When the time server is in NTP broadcast mode, this is an integer

indicating the maximum interval between successive NTP messages, in

seconds to the nearest power of two. For example a value of 6 means

2^6 or 64 seconds. Note: a primary time server's outgoing NTP packet
