Changing the clock setting using Device Manager

Before you can pass traffic using the Passport 8672ATME Module with its installed MDA, you must change the clock setting.

Note: The Passport 8672ATME Module supports only Ethernet ELANs.

Note: If you are connecting one Passport 8672ATME Module directly to another Passport 8672ATME Module without going through the SONET cloud, the clock mode at both ends of the circuit may be free-running, but only one end of this circuit may be configured as loop-timed.

To change the clock setting using Device Manager:

1. Highlight the port.
2. Choose Edit > Port.

The Port dialog box opens with the Interface tab displayed.

3. Click the ATM tab.
4. To set the clock setting, in the ClockSource section, click loopTimed or freeRunning.
5. Click Apply.
