Setting a Mapped SSM Quality Level of a UNK Clock Source

Setting a Mapped SSM Quality Level of a UNK Clock Source


Unknown (UNK) indicates that the SSM quality level of a clock source is unknown. The clock source with the SSM quality level UNK cannot participate in clock source selection. If this clock source needs to be permitted, map it to a valid SSM quality level.


  1. Run system-view

    The system view is displayed.

  2. Run clock map unk { dnu | prc | sec | ssua | ssub }

    The clock source with the SSM quality level UNK is mapped to an SSM quality level.

    By default, no SSM quality level is mapped to a clock source with the SSM quality level UNK.

  3. Run commit

    The configuration is committed.
