Module: DOCS-RPHY-PTP-MIB

OID (symbolic): DOCS-RPHY-PTP-MIB::docsRphyPtpCcapParentDataSetGmQualityClass

OID (numeric): 1.3.6.1.4.1.4491.2.1.32.1.2.3.9

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-only

Description: This attribute is the clock class for the grandmaster clock. The clock class attribute of an ordinary or boundary clock denotes the traceability of the time or frequency distributed by the grandmaster clock. See section 7.6.2.4 in [IEEE 1588].

What is docsRphyPtpCcapParentDataSetGmQualityClass?

This OID reports the clock class of the current grandmaster clock, indicating how traceable its time or frequency source is (per IEEE 1588 section 7.6.2.4). Admins use this to judge the trustworthiness of the timing source actually feeding this CCAP's PTP hierarchy.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4491.2.1.32.1.2.3.9
snmpwalk -v2c -c public <target> DOCS-RPHY-PTP-MIB::docsRphyPtpCcapParentDataSetGmQualityClass

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4491.2.1.32.1.2.3.9.1
snmpget -v2c -c public <target> DOCS-RPHY-PTP-MIB::docsRphyPtpCcapParentDataSetGmQualityClass.1
