Configure Port Speed at Chassis Level and Interface Level

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

Step 1: To indicate the speed at which the ports operate, configure the speed statement for the desired interfaces.

user@host# set speed (10G | 25G | 40G | 50G| 100G | 400G)

For example:

[edit interfaces et-1/0/3] user@host# set speed 100g

For example:

[edit interfaces et-1/0/3] user@host# set speed 100g

Step 2: To configure the speed for a group of ports.

[edit ] user@host# wildcard range set interfaces interface-name speed speed

For example:

[edit ] user@host# wildcard range set interfaces et-1/0/[0-5] speed 100g

[edit ] user@host# wildcard range set interfaces interface-name speed speed

For example:

[edit ] user@host# wildcard range set interfaces et-1/0/[7-12] speed 100g

Step 3: To specify the number of interfaces you want to configure per port.

Not applicable

[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 4

In this example, in Step 1 and Step 2, you configure 4x100GE channelized interfaces.

Step 4: (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 unused

In this example, no interfaces (channelized or non-channelized) are created on port 3 of the line card installed in the FPC slot 2.

[edit] user@host# set interfaces interface-name unused

For example:

[edit] user@host# set interfaces et-2/0/4 unused

In this example, no interfaces (channelized or non-channelized) are created on port 4 of the line card installed in the FPC slot 2.

Step 5: Verify the configuration.

et-x/y/z { speed 100g;

unit 0 { ... } ... unit N { ... } } ... et-x/y/z { unused;

et-x/y/z { speed 100g; number-of-sub-ports 4;

et-x/y/z:0 { unit 0{ ... } }

et-x/y/z:1 { unit 0{ ... } }

et-x/y/z:2 { unit 0{ ... } }

et-x/y/z:3 { unit 0{ ... } }

... et-x/y/z:6 { unused;

Step 6: Commit the configuration.
