Configuring Port Speed on PTX10K-1201 line card to Enable Different Port Speeds

 

Rate selectability enables you to configure the port speed either at the port level or at the PIC level. To configure all ports to operate at the same speed, configure rate selectability at the PIC level, in which case you cannot configure the speed of individual ports. To configure rate selectability at the PIC level, use the pic-mode statement and specify the port speed. To configure different port speeds for each port, configure rate selectability at the port level, in which case only the ports that are configured are enabled. To configure rate selectability at the port level, use the speed statement to specify the speed of individual ports. This topic describes how to configure port speeds at the port level and at the PIC level.

Configuring Port Speed on PTX10K-1201 line card at PIC Level

To configure all ports to operate at the same speed, configure rate selectability at the PIC level. When you configure rate selectability at the PIC level, all the ports of the PIC that support the configured speed operate at that speed. The PTX10K-LC1201 line card supports port speeds of 10 Gbps, 25 Gbps, 40 Gbps, 50 Gbps, 100 Gbps, 200 Gbps, and 400 Gbps.

To configure rate selectability at the PIC level:

  1. In configuration mode, navigate to the [edit chassis fpc fpc-slot pic pic-number] hierarchy level.

    For example:

  2. Configure the pic-mode pic-speed statement to set the operating speed for the PIC. All ports of the PIC that support the configured speed operate at the configured speed. Values for the pic-speed option are 10 Gbps, 25 Gbps, 40 Gbps, 50 Gbps, 100 Gbps, 200 Gbps, and 400 Gbps.

    For example:

  3. Verify the configuration.
  4. Commit your configuration changes.

In this example, you have configured all ports on the line card with port speed of 200 Gbps.

Configuring Port Speed on PTX10K-LC1201 line card at Port Level

To configure different port speeds for each port, you configure rate selectability at the port level. Configuring rate selectability at the port level provides you the flexibility of operating individual ports of the PIC at different supported speeds.

To configure rate selectability at the port level:

  1. In configuration mode, navigate to the [edit chassis fpc fpc-slot pic pic-number] hierarchy level.

    For example:

  2. To indicate the speed at which the ports operate, configure the speed statement for the desired ports. Values supported are 10 Gbps, 25 Gbps, 40 Gbps, 50 Gbps, 100 Gbps, 200 Gbps, and 400 Gbps. You can also specify the number of sub ports that you wish to configure.

    For example:

  3. Verify the configuration.
  4. Commit your configuration changes.

In this example, you have configured port 0 to operate at 4x10 Gbps speed.

Note

When you configure the port speed and number of sub ports, the configured values override the default port speed for the transceiver. If you try to configure a port speed that is not supported by the transceiver, the port will be disabled.
