ntpSysRootDelay OBJECT-TYPE

SYNTAX Counter

MAX-ACCESS read-only

STATUS current

DESCRIPTION

“This is a raw 32 bit number representing a signed fixed point 32-bit

number indicating 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 Counter

MAX-ACCESS read-only

STATUS current

DESCRIPTION

“This is a raw 32 bit number representing a signed 32-bit fixed-point

number indicating 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 will have 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 identifying 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:
