Set Clocking to Internal


You set clocking to internal because there is no external clock source in a loopback connection.


To configure clocking to internal, follow these steps:

  1. In configuration mode, go to the following hierarchy level:
    [edit]user@host# edit interfaces interface-name
  2. Configure the clocking to internal:
    [edit interfaces interface-name]user@host# set clocking internal
  3. Verify the configuration:
    user@host# show

    For example:

    [edit interfaces t1-1/3/0]user@host# show clocking internal;
  4. Commit the change:
    user@host# commit

    For example:

    [edit interfaces t1-1/3/0]user@host# commit commit complete


This command saves the clocking change to the configuration database, activates the configuration on the router, and exits configuration mode.
