tnPtpSystemFrequencyReference
Module: TROPIC-PTP-MIB
OID (symbolic): TROPIC-PTP-MIB::tnPtpSystemFrequencyReference
OID (numeric): 1.3.6.1.4.1.7483.2.2.4.9.1.1.1.1.2
Node type: OBJECT-TYPE
Type: Integer32
Access: read-create
Description: This parameter determines the frequency reference for the PTP clocks in the card. It is intended to be managed by the System Operator.
This parameter is valid when the tnPtpSystemClockMode = 1/2/3/6/7/8
0: the local PTP clock uses the physical layer frequency reference, and this clock is syntonized with the PTP master. 1: the local PTP clock uses the physical layer frequency reference, but this clock is' unsyntonized with the PTP master. 2: the local PTP clock uses the packet layer frequency reference which is recovered from the PTP.
What is tnPtpSystemFrequencyReference?
Chooses where this card's local PTP clock gets its frequency reference from: the physical layer clock unsyntonized with the PTP master, the same physical layer clock but syntonized to the master, or the packet-layer frequency recovered from PTP itself. It only applies when the card is running as an Ordinary or Boundary Clock, and choosing packet-recovered frequency is typically needed when no independent physical-layer timing reference is available.
