Example: Configure Synchronous Ethernet

CLI Quick Configuration

To quickly configure synchronization on the aforementioned routers, copy the following commands, paste them in a text file, remove any line breaks, and then copy and paste the commands into the CLI.

set chassis synchronization clock-mode auto-select
set chassis synchronization network-type option-1
set chassis synchronization quality-mode-enable
set chassis synchronization selection-mode configured-quality
set chassis synchronization switchover-mode revertive
set chassis synchronization hold-interval configuration-change 1 restart 1 switchover 1
set chassis synchronization esmc-transmit interfaces ge-2/0/0
set chassis synchronization source external-a priority 2 quality-level prc request force-switch
set chassis synchronization interfaces ge-2/0/0 priority 1 quality-level prc request force-switch wait-to-restore 1

Procedure

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 in the CLI User Guide.

To configure Synchronous Ethernet, perform the following tasks:

1. Configure the clock mode, network type, quality mode, selection mode, and switchover mode.

   content_copy zoom_out_map

   [edit chassis synchronization]
   user@host# set clock-mode auto-select network-type option-1 quality-mode-enable selection-mode configured-quality switchover-mode revertive
   

2. Configure the hold interval for configuration change, restart interval, and the switchover interval in seconds.

   content_copy zoom_out_map

   [edit chassis synchronization]
   user@host# set hold-interval configuration-change 1 restart 1 switchover 1
   

3. Configure the interfaces for transmitting ESMC.

   content_copy zoom_out_map

   [edit chassis synchronization]
   user@host# set esmc-transmit interfaces ge-2/0/0
   

4. Configure the source node with its quality level, priority, and request type.

   content_copy zoom_out_map

   [edit chassis synchronization]
   user@host# set source external-a priority 2 quality-level prc request force-switch
   

5. Configure the interfaces with priority, quality level, request type, and time to restore the interface to default.

   content_copy zoom_out_map

   [edit chassis synchronization]
   user@host# set interfaces ge-2/0/0 priority 1 quality-level prc request force-switch wait-to-restore 1
   

Results

Display the results of the configuration:

user@host# show chassis
synchronization {
    clock-mode auto-select;
    esmc-transmit {
        interfaces ge-2/0/0;
    }
    hold-interval {
        configuration-change 1;
        restart 1;
        switchover 1;
    }
    network-type option-1;
    quality-mode-enable;
    selection-mode configured-quality;
    switchover-mode revertive;
    source {
        external-a {
            priority 2;
            quality-level prc;
            request force-switch;
        }
        interfaces ge-2/0/0 {
            priority 1;
            quality-level prc;
            request force-switch;
            wait-to-restore 1;
        }
    }
}
