SYNTAX INTEGER (-127..127)
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"This integer indicates the ultimate precision of the
synchronizing clock, in seconds, to the nearest power of two. Note: A
primary time server's outgoing NTP packet will have its precision
field set to ntpSysPrecision."
::= { ntp 11 }
ntpSysRootDelay OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"This raw 32 bit number represents a signed fixed point 32-bit
number. This is the total round-trip delay to the primary
synchronization clock source, in seconds, with the fraction point
between bits 15 and 16. Note that this variable can take on both
positive and negative values, depending on clock precision and skew.
Note: A primary time server's outgoing NTP packet will have its root
delay field set to ntpSysRootDelay."
::= { ntp 12 }
ntpSysRootDisp OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"This raw 32-bit number represents a signed 32-bit fixed-point
number. This is the maximum error relative to the primary reference
source, in seconds, with fraction point between bits 15 and 16. Only
positive values greater than zero are possible. Note: A primary time
server's outgoing NTP packet has its root dispersion field set
to ntpSysRootDisp."
::= { ntp 13 }
ntpSysRefClockIdent OBJECT-TYPE
SYNTAX DisplayString (SIZE (0..4))
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"This is a four byte ASCII string that identifies the particular reference
clock. In the case of stratum 0 (unspecified) or stratum 1 (primary
reference), this is a four-octet, left-justified, zero-padded ASCII
string. While not enumerated as part of the NTP specification, the
following are suggested ASCII identifiers:
