Configuring the Clock Mode

Configuring the Clock Mode

Context

A POS interface supports the following clock modes:

  • master: uses the internal clock signal.
  • slave: uses the line clock signal.
  • system: uses the MPU clock signal.

When the POS interfaces of the router and a remote device are directly connected, set the clock mode of one end to master and that of the peer end to slave. When the POS interface of a device is connected to the SONET or SDH network, set the clock mode of the POS interface to slave because the SONET or SDH network clock has a higher accuracy than the POS interface.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface pos interface-number

    The POS interface view is displayed.

  3. Run clock { master | slave | system }

    The clock mode is set for the POS interface.

    By default, the clock mode of a POS interface is slave.
