Precision Time Protocol (PTP)

  • Support for Synchronous Ethernet over LAG support (ACX7024, ACX7100-32C, and ACX7100-48L)—Starting in Junos OS Evolved Release 23.4R1, ACX7100-32C, ACX7100-48L, and ACX7024the listed ACX Series routers support Synchronous Ethernet over a Link Aggregation Group (LAG). You can now define a LAG while configuring the Synchronous Ethernet clock source on these routers.

  • Support for G.8275.1 over LAG and Synchronous Ethernet over LAG (ACX7509)—Starting in Junos OS Evolved Release 23.4R1, the ACX7509 router supports G.8275.1 profile over link aggregation group (LAG) and Synchronous Ethernet over LAG with the following ITU recommendations:

    • G.8262/G.8262.1—Specifies timing characteristics of Synchronous Ethernet equipment clock (ECC).

    • G.8264—Describes the Ethernet Synchronization Message Channel (ESMC).
