juniNtpSysClockRootDispersion

Module: Juniper-System-Clock-MIB

OID (symbolic): Juniper-System-Clock-MIB::juniNtpSysClockRootDispersion

OID (numeric): 1.3.6.1.4.1.4874.2.2.56.2.1.5

Node type: OBJECT-TYPE

Type: JuniNtpClockUnsignedTime

Access: read-only

Description: This indicates the maximum error relative to the primary reference source at the root of the synchronization subnet, in seconds. Only positive values greater than zero are possible.

What is juniNtpSysClockRootDispersion?

The maximum error relative to the primary reference source at the root of the NTP synchronization subnet, in seconds, per its DESCRIPTION, always a positive value. A growing root dispersion indicates the overall accuracy of the router's time is degrading even if it's still nominally synchronized.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.56.2.1.5
snmpwalk -v2c -c public <target> Juniper-System-Clock-MIB::juniNtpSysClockRootDispersion

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.56.2.1.5.1
snmpget -v2c -c public <target> Juniper-System-Clock-MIB::juniNtpSysClockRootDispersion.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> juniNtpSysClockRootDispersion.1
