Configure Port Speed at Chassis Level

Learn how to configure port speed at PIC level and port level in chassis hierarchy.

Configure Port Speed at PIC Level

To configure port speed 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 statement to set the operating speed for the PIC's ports. According to your requirements, you can choose from the options 10G, 40G, or 100G.

    For example:

  3. (Optional) To prevent oversubscription, you can choose to configure the number of ports that operate at the mode that is configured in Step 2.

    For example:

  4. Verify the configuration.

  5. Commit your configuration changes.

Configure Port Speed at 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. According to your requirements, you can choose the 10g, 40g, or 100g speed options.

    For example:

  3. Verify the configuration.

    You can verify the 40-Gbps and 100-Gbps ports configured as 10-Gbps by using the show interfaces terse command.

  4. Commit your configuration changes.

Configuration Steps

Details

Example

Channelize Individual Port: Configure an individual port to operate at a specific channel speed. Specify a port number and channel speed.

[edit chassis fpc fpc-slot pic pic-slot]

user@host# set port port-number channel-speed speed

To configure an individual 40-Gigabit Ethernet (et) port to operate as 10-Gigabit Ethernet (xe) ports, specify a port number and channel speed.

[edit chassis fpc 0 pic 0] user@host# set port 3 channel-speed 10g

Channelize Block of Ports: Channelize a block of ports. Specify a port range and channel speed.

[edit chassis fpc fpc-slot pic pic-slot]

user@host# set port-range port–range-low port-range-high channel-speed speed

To configure ports 0 through 3 on PIC 0 to operate as 50-Gigabit Ethernet ports:

[edit chassis fpc 0 pic 0] user@host# set port-range 0 3 channel-speed 50g

Configure Speed per Quad: Configure port speeds only per quad (group of 4 ports) and not individually. Specify the speed for the first port of the quad ports. All ports operate at a single speed within the quad.

[edit chassis fpc fpc-slot pic pic-slot]

user@host# set port port–number speed speed

To configure ports 4 through 7 to operate as 25-Gigabit Ethernet ports, you must configure port 4 to operate as 25-Gigabit Ethernet ports.

[edit chassis fpc 0 pic 0]

user@host# set port 4 speed 25g

Configure Speed on an Individual Port

[edit chassis fpc fpc-slot pic pic-slot]

user@host# set port port–number speed speed

[edit chassis fpc 0 pic 0]

user@host# set port 3 speed 25g
