Example: Configure Hybrid Mode and ESMC Quality-Level Mapping on MX240 Router

CLI Quick Configuration

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.

[edit]
set protocols ptp slave hybrid
set protocols ptp slave hybrid synchronous-ethernet-mapping
set protocols ptp slave hybrid synchronous-ethernet-mapping clock-source 2.2.2.2 interface ge-1/2/3.0
set protocols ptp slave convert-clock-class-to-quality-level

Step-by-Step Procedure

To configure hybrid mode on an MX240 router with mapping of the PTP clock class to the ESMC quality level, perform the following steps:

1. Configure the convert-clock-class-to-quality-level option on the timeReceiver at the [edit protocols ptp slave] hierarchy level.

   content_copy zoom_out_map

   [edit protocols ptp slave]
   user@host# set convert-clock-class-to-quality-level
   

2. Configure hybrid mode on the timeReceiver.

   content_copy zoom_out_map

   [edit protocols ptp slave]
   user@host# edit hybrid
   

3. Configure the Synchronous Ethernet mapping option, IP address of the timeTransmitter clock as 2.2.2.2, and the interface ge-1/2/3.0 for hybrid mode on the timeReceiver.

   content_copy zoom_out_map

   [edit protocols ptp slave hybrid]
   user@host# set synchronous-ethernet-mapping clock-source 2.2.2.2 interface ge-1/2/3.0
   

Results

Display the results of the configuration of hybrid mode with the mapping of the PTP clock class to the ESMC quality level:

[edit protocols ptp slave]
user@host# show
convert-clock-class-to-quality-level
hybrid {
    synchronous-ethernet-mapping {
        clock-source 2.2.2.2 {
        interface  ge-1/2/3.0;
        }
    }
}

CLI Quick Configuration

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

[edit]
set protocols ptp slave hybrid
set protocols ptp slave hybrid synchronous-ethernet-mapping
set protocols ptp slave hybrid synchronous-ethernet-mapping clock-source 2.2.2.2 interface ge-1/2/3.0
set protocols ptp slave clock-class-to-quality-level-mapping quality-level prc clock-class 80

Step-by-Step Procedure

To configure hybrid mode with a user-defined mapping of the PTP clock class to the ESMC quality level on an MX240 router, perform the following steps:

1. Configure the quality-level option for the clock-class-to-quality-level-mapping statement on the timeReceiver at the [edit protocols ptp slave] hierarchy level and then configure the clock-class option for the set quality level if you want to manually override the mapping of the ESMC quality level to the clock class.

   content_copy zoom_out_map

   [edit protocols ptp slave]
   user@host# set clock-class-to-quality-level-mapping quality-level prc clock-class 80
   

2. Configure hybrid mode on the timeReceiver.

   content_copy zoom_out_map

   [edit protocols ptp slave]
   user@host# edit hybrid
   

3. Configure the Synchronous Ethernet mapping option, IP address of the timeTransmitter clock as 2.2.2.2 , and the interface ge-1/2/3.0 for hybrid mode on the timeReceiver.

   content_copy zoom_out_map

   [edit protocols ptp slave hybrid]
   user@host# set synchronous-ethernet-mapping clock-source 2.2.2.2 interface ge-1/2/3.0
   

Results

Display the results of the configuration of hybrid mode with a user-defined mapping of the PTP clock class to the ESMC quality level:

[edit protocols ptp slave]
user@host# show
clock-class-to-quality-level-mapping {
    quality-level prc {
        clock-class 80;
    }
}
hybrid {
    synchronous-ethernet-mapping {
        clock-source 2.2.2.2 {
        interface ge-1/2/3.0;
        }
    }
}

Purpose

Verify the current mode of operation of the timeReceiver.

Action

In operational mode, enter the run show ptp hybrid command to display the current configuration and current mode of operation of the timeReceiver.

In operational mode, enter the run show ptp hybrid config command to display the PTP source to Synchronous Ethernet interface mappings.

In operational mode, enter the run show ptp hybrid status command to display the current hybrid mode operational status.

Meaning

The output displays the current configuration and current mode of operation of the timeReceiver. For information about the run show ptp hybrid operational command, see show ptp hybrid.

Purpose

Verify the quality level change on the transmit side of the router.

Action

In operational mode, enter the run show synchronous-ethernet esmc transmit detail command to display the ESMC transmit interface details.

Meaning

The output displays the ESMC SSM quality level transmitted out of various Ethernet interfaces. For information about the run show synchronous-ethernet esmc transmit detail operational command, see show synchronous-ethernet esmc transmit.

Purpose

Verify the global information parameters after mapping of the PTP clock class to the ESMC quality level in hybrid mode by enabling the convert-clock-class-to-quality-level option.
