Configuring a Clock Source ID to Prevent Timing Loops

Configuring a Clock Source ID to Prevent Timing Loops

Context

Timing loops occur if the clock signals sent from a clock source are received by the sender. To address this issue, configure clock IDs. In extended SSM mode, the higher four bits of the S1 bytes are used to transmit the clock source ID.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run clock id id source source

    The ID of a clock source is set.

    The default ID of a clock source is 0.

  3. (Optional) Run clock no-id-out { bits0 | bits1 }

    The BITS0 or BITS1 interface is disabled from sending the ID of the clock source.

  4. (Optional) Run interface interface-type interface-number

    The interface view is displayed.

  5. (Optional) Run clock no-id-out

    The interface is disabled from sending the ID of the clock source.
