Precision Time Protocol (PTP)

  • Support for Precision Time Protocol (PTP) G.8275.2 enhanced profile over LAG with IPv4, IPv6 or mixed mode unicast traffic (MX10K-LC2101 on MX10008)—Starting in Junos OS Release 23.4R1, the MX10K-LC2101 line card on MX10008 platform supports the PTP G.8275.2 enhanced profile. This is based on Partial Timing Support (PTS) using unicast PTPoIPv4 and PTPoIPv6. The G.8275.2 enhanced profile complies with the performance requirements for T-BC-P/T-TSC-P node types as specified in the ITU-T G.8273.4 specification. This feature provides you flexibility to relax the frequency and phase offsets required for a lock by configuring the frequency-lock-threshold and phase-lock-threshold configuration knobs respectively. In addition, it helps relax the maximum phase offset to adjust in phase-aligned state by configuring the phase-adjust-threshold knob in the PTP configuration.
