To configure the router in hybrid mode, you must:
Configure Synchronous Ethernet options at the
1.
level:
Configure the
auto-select
from a free-run local oscillator or from an external qualified clock.
When the router is configured with the
two best upstream clock sources. It then uses the clock recovered from one of the
sources to lock the chassis clock. If an upstream clock with acceptable quality is
not available or if the router is configured in free-run mode, the router uses the
internal oscillator.
Configure the
esmc-transmit
synchronization] hierarchy level.
Configure one or more interfaces at the
as Synchronous Ethernet sources as needed.
Configure PTP options at the
2.
Configure hybrid mode options at the
3.
The following example requires you to navigate various levels in the configuration
hierarchy. For instructions on how to do that, see Using the CLI Editor in Configuration
Mode.

To quickly configure hybrid mode on the ge-1/2/3.0 interface with the clock source IP
address as 2.2.2.2, copy the following commands, paste them in a text file, remove any
line breaks, and then copy and paste the commands into the CLI.
