When the 2M ring does not trace the source, the output action ("clock bits { bits0 | bits1 | bits2 } lti-action-2mbps { send-dnu | send-ais }") of the BITS port is valid only when the BITS signal type is set to 2mbps. |

In the port extension scenario, the inter-device clock synchronization solution supports only physical-layer clock synchronization and 1588v2 time synchronization. |

NetEngine 8000 F2A/NetEngine 8000 F1A |
O/E converters do not support synchronous Ethernet or PTP time synchronization. The frequency/time synchronization performance cannot be met. When planning the clock/time topology, do not deploy the clock/time source on an interface with an O/E conversion module. Instead, use an optical module or an electrical interface. |

NetEngine 8000 F2A/NetEngine 8000 F1A |
The clock source with an abnormal frequency offset can participate in clock source selection again only when frequency offset detection is enabled and the frequency offset switching function is enabled. |
