    hybrid (ACX Series)

    Syntax

    hybrid;

    Hierarchy Level

    [edit protocols ptp slave]

    Release Information

    Statement introduced in Junos OS Release 12.3X54 for ACX Series routers.

    Description

    Configure hybrid mode. When you configure hybrid mode, the following processes take place.

    • The best of the configured PTP time sources is selected by the PTP Best Master Clock Algoritm (BMCA).
    • The best of configured chassis synchronization sources is selected by the synchronization source selection algorithm.
    • During the boot-up process, if valid sources are configured at the [edit chassis synchronization] hierarchy level and chassis synchronization mode in free-running mode, valid PTP source available case, system continues to operate in hybrid mode ( In this case, chassis synchronization is in free-run mode, whereas PTP is in locked mode). When both primary and secondary frequency sources fail, system still works under hybrid mode ( In this case, chassis synchronization is in hybrid mode and PTP is in locked mode).

    Note: ACX Series routers support only the hybrid statement in the [edit protocols ptp slave] configuration stanza . Unlike MX Series routers, the synchronous-ethernet-mapping option is not supported as a substatement at the [edit protocols ptp slave hybrid] hierarchy level. If you enable hyrbid mode, you must also configure the Synchronous Ethernet options at the [edit chassis synchronization] hierarchy level. The clock source IP address and interfaces you configure at the [edit protocols ptp slave unicast-mode] hierarchy level function as Synchronous Ethernet mapping settings.
