Set Clocking to Internal

Purpose

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

Action

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

Meaning

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