Configuring the Port Speed on the JNP10K-LC1201 by Using New Port Profile Configuration
This topic describes the JNP10K-LC1201 line card, the guidelines for configuring the port speed and how to configure the port speed using the new port profile configuration.
Understanding New Port Profile Configuration
The JNP10K-LC1201 line card is a fixed-configuration line card with 36 built-in ports. The ports on the JNP10K-LC1201 support multiple port speeds. The default port speed is 400Gbps for all ports. Each JNP10K-LC1201provides a maximum bandwidth of 14.4Tbps.
On the JNP10K-LC1201, you can choose to configure all 36 ports with the following port speeds:
40 Gbps, 100 Gbps, 400 Gbps
Table 1 summarizes the Packet Forwarding Engine mapping and the supported port speeds.

PIC | Port Number | Port Speed Supported | Optics Supported |
|---|---|---|---|
PIC 0 | 0-35 | 4x10-Gigabit Ethernet 1x40-Gigabit Ethernet 4x25-Gigabit Ethernet 8x25-Gigabit Ethernet 2x50-Gigabit Ethernet 1x100-Gigabit Ethernet 2x100-Gigabit Ethernet 4x100-Gigabit Ethernet 1x400-Gigabit Ethernet |
Note: By default, all the active ports operate in 400-Gigabit Ethernet mode. |
Starting in Junos OS Evolved Release 20.1R2, we now support a new port profile configuration to configure port speeds on the JNP10K-LC1201 line card. You can now configure the port speed on the JNP10K-LC1201 line card by using the port profile configuration commands in the [edit interfaces] hierarchy. To streamline the configuration, the new port profile configuration commands are migrated from the [edit chassis] hierarchy to the [edit interfaces] hierarchy for the JNP10K-LC1201 line card.
Guidelines for Configuring the Port Speed Using new Port Profile Configuration
This topic describes the guidelines to consider when configuring rate selectability using the new port profile configuration:
On non-channelized interfaces, the prefix et- is used irrespective of the speed configured. If you do not configure the speed, by using the optional speed command, default speed is assigned to the interface.
On channelized interfaces, the prefix et- is used irrespective of the speed configured. All channelized interfaces have the same speed. You cannot configure an individual speed for each channelized interface. You can configure the number of channelized interfaces by using the number-of-sub-ports command.
You can configure the active physical ports in a PIC. By default, all the physical ports in an interface are active. To control the number of interfaces created on a physical port in a PIC, use the unused command. If you configure a port as unused, no interfaces (channelized or non-channelized) are created for that port.
When you change the speed of the port, or change the number-of-sub-ports per port, or configure or remove the number-of-sub-ports, the interfaces will be deleted and re-created for that port.
If you have not configured the port profile for a specific port and the port is active, interfaces are created for the port with default speed based on the platform or FPC. You can control the number of interfaces created by using the unused command.
Interfaces are created irrespective of the physical presence of optics. If the plugged in optics does not match the interface speed, the interfaces are marked down.
You can configure port profiles in the command line interface without the physical presence of an FPC. If an invalid port profile configuration is detected while booting a FPC, an alarm is generated. Also, the default port profile is selected for that PIC. Also, if the port profile configuration is changed while the FPC is up and running, and the new configuration is invalid, an alarm is generated. The existing port profile configured continues to be used for that PIC.
Configuring Port Speed on JNP10K-LC1201 by using New Port Profile Configuration
In earlier releases, you configured the port speed by using the interface commands in the port profile configuration which was part of the [edit chassis] hierarchy. You can now configure the port speed on the JNP10K-LC1201 line card by using the port profile configuration commands in the [edit interfaces] hierarchy.
To configure the port speed for non-channelized interfaces on JNP10K-LC1201 :
- In configuration mode, navigate to the [edit interfaces interface-name] hierarchy level.[edit ]user@host# edit interfaces interface-name
For example:
[edit ]user@host# edit interface et-1/0/3 - To indicate the speed at which the ports operate, configure
the speed statement for the desired interfaces. Values
supported are 10 Gbps, 25 Gbps, 40 Gbps, 50 Gbps, 100 Gbps, and 400
Gbps.[edit interfaces interface-name]user@host# set speed (10g | 25g | 40g | 50g| 100g | 400g)
For example:
[edit interfaces et-1/0/3]user@host# set speed 100g - (Optional) To control the number of interfaces created
on a physical port, use the unused statement. If you configure
a port as unused, no interfaces are created for that port irrespective
of the port profile configuration for that port.[edit]user@host# set interfaces interface-name unused
For example:
[edit]user@host# set interfaces et-2/0/3 unusedNo interfaces (channelized or non-channelized) are created on port 3 of the JNP10K-LC1201 line card installed in the FPC slot 2.
To configure the port speed for channelized interfaces on JNP10K-LC1201:
- In configuration mode, navigate to the [edit interfaces interface-name] hierarchy level.[edit ]user@host# edit interfaces interface-name
For example:
[edit ]user@host# edit interface et-1/0/3 - To indicate the speed at which the ports operate, configure
the speed statement for the desired interfaces. Values
supported are 10 Gbps, 25 Gbps, 40 Gbps, 50 Gbps, 100 Gbps, and 400
Gbps.[edit interfaces interface-name]user@host# set speed (10g | 25g | 40g | 50g| 100g | 400g)
For example:
[edit interfaces et-1/0/3]user@host# set speed 100g - To specify the number of interfaces per port that you
want to configure, use the number-of-sub-ports statement. [edit interfaces interface-name]user@host# set number-of-sub-ports number-of-sub-ports
For example:
[edit interfaces et-1/0/3]user@host# set number-of-sub-ports 4In Step 2 and Step 3, you have configured 4x100GE channelized interfaces.
- (Optional) To control the number of interfaces created
on a physical port, use the unused statement. If you configure
a port as unused, no interfaces are created for that port irrespective
of the port profile configuration for that port.[edit]user@host# set interfaces interface-name unused
For example:
[edit]user@host# set interfaces et-2/0/4 unusedNo interfaces (channelized or non-channelized) are created on port 4 of the JNP10K-LC1201 line card installed in the FPC slot 2.
