Description: This attribute is the offset, scaled, logarithmic representation of the clock variance. See Section 7.6.3.5 in [IEEE 1588].
What is docsRphyPtpCcapDefaultDataSetQualityOffset?
This OID is the scaled logarithmic representation of the CCAP clock's variance, per IEEE 1588 section 7.6.3.5, used alongside class and accuracy to rank clock quality during grandmaster selection. Admins would examine this value only when deep-diagnosing PTP master-selection behavior rather than in routine monitoring.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4491.2.1.32.1.2.1.8 snmpwalk -v2c -c public <target> DOCS-RPHY-PTP-MIB::docsRphyPtpCcapDefaultDataSetQualityOffset
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.4491.2.1.32.1.2.1.8.1 snmpget -v2c -c public <target> DOCS-RPHY-PTP-MIB::docsRphyPtpCcapDefaultDataSetQualityOffset.1
