Description: This attribute represents the offset, scaled, logarithmic representation of the grandmaster clock variance. See Section 7.6.3.5 in [IEEE 1588].
What is docsRphyPtpCcapParentDataSetGmQualityOffset?
This OID reports the scaled logarithmic variance of the current grandmaster clock, per IEEE 1588 section 7.6.3.5, one of the quality metrics used during master selection. It's mainly useful for detailed PTP diagnostics rather than day-to-day monitoring.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4491.2.1.32.1.2.3.11 snmpwalk -v2c -c public <target> DOCS-RPHY-PTP-MIB::docsRphyPtpCcapParentDataSetGmQualityOffset
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.4491.2.1.32.1.2.3.11.1 snmpget -v2c -c public <target> DOCS-RPHY-PTP-MIB::docsRphyPtpCcapParentDataSetGmQualityOffset.1
