Module: DOCS-RPHY-PTP-MIB
OID (symbolic): DOCS-RPHY-PTP-MIB::docsRphyPtpCcapTimePropertiesTimeSource
OID (numeric): 1.3.6.1.4.1.4491.2.1.32.1.2.4.8
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: This attribute represents the source of time used by the grandmaster clock. See Table 7 in [IEEE 1588]. If the time source of the grandmaster clock is unknown, the CCAP Core MUST set the TimeSource value to INTERNAL_OSCILLATOR (0xA0).
What is docsRphyPtpCcapTimePropertiesTimeSource?
This OID reports a code (0-255, per IEEE 1588 Table 7) identifying what time source feeds the grandmaster clock, such as GPS or an internal oscillator; if unknown, the CCAP core reports INTERNAL_OSCILLATOR (0xA0). Admins check this to confirm the grandmaster is locked to a real external reference like GPS rather than free-running on its own oscillator.
