This topic provides you with information about how to configure port speed in port level and PIC level at chassis and interface hierarchy.

Configure Port Speed - PIC Level

To configure the operating port speed in the PIC level at chassis heirarchy, follow these steps:

In the [edit chassis] fpc fpc-slot pic pic-number hierarchy level, configure the port speed using the set pic-mode pic-speed command.
```
[edit chassis fpc 0 pic 0]
user@host# set pic-mode 100g
```
Configure the number of active physical ports that operate at the configured speed.
```
[edit chassis fpc 0 pic 0]
user@host# set number-of-ports 4
```
Specify the number of logical interfaces you want to create on a physical port.
```
[edit chassis fpc 0 pic 1]
user@host# set number-of-sub-ports 4
```
Specify the port number that you want to power off.
```
[edit chassis fpc 0 pic 1]
user@host# set port 2 unused 
```

Verify the configuration.

content_copy zoom_out_map
[edit chassis fpc 0 pic 0]
user@host# show 
pic-mode 100G;
number-of-ports 4;

Commit the configuration.
```
[edit chassis fpc 0 pic 0]
user@host# commit
```

Configure Port Speed - Port Level

To configure the operating port speed in the port level at chassis hierarchy, follow these steps:

In the [edit chassis] fpc fpc-slot pic pic-number hierarchy level, configure the port speed using the set port port-number speed (10g | 40g | 100g) command.
```
[edit chassis fpc 0 pic 0]
user@host# set port 0 speed 40g
set port 0 speed 100g
```
Specify the number of logical interfaces you want to create on a physical port.
```
[edit chassis fpc 0 pic 1]
user@host# set number-of-sub-ports 4
```
Specify the port number that you want to power off.
```
[edit chassis fpc 0 pic 1]
user@host# set port 2 unused 
```

Verify the configuration.

content_copy zoom_out_map
[edit chassis fpc 0 pic 0]
user@host# show port 0 {
    speed 40g;
}
port 1 {
    speed 100g;
}
[edit chassis fpc 0 pic 1]
user@host# show 
port 1 {  
number-of-sub-ports 4;
}

Commit the configuration.
```
[edit chassis fpc 0 pic 0]
user@host# commit
```

Configure Port Speed for Non-Channelized Interfaces

To configure the operating port speed for non-channelized interface at the interface hierarchy, follow these steps:

To specify the port speed, in the [edit interface interface-name hierarchy level, configure the speed value using the set speed (10g | 25g | 40g | 50g | 100g | 400g) command.
```
[edit interfaces et-1/0/3]
user@host# set speed 100g
```
To configure the speed for a group of ports, in the [edit wildcard range interface interface-name hierarchy level, configure the speed value using the set speed (10g | 25g | 40g | 50g | 100g | 400g) command.
```
[edit wildcard range set interfaces et-1/0/[0-5]
user@host# set speed 100g
```
To control the number of interfaces created on a physical port, use the unused statement.
```
[edit interfaces et-2/0/3]
user@host# set unused 
```
Note:
In this example, no interfaces (channelized or non-channelized) are created on port 3 of the line card installed in the FPC slot 2.

Verify the configuration.

content_copy zoom_out_map
[edit interfaces]
user@host# et-x/y/z { 
    speed 100g;
    unit 0 { 
        ...
    } 
    ... 
    unit N {
        ... 
    }
}
...
et-x/y/z { 
unused;
}

Commit the configuration.
```
[edit interfaces et-1/0/3]
user@host# commit
```

Configure Port Speed for Channelized Interfaces

To configure the operating port speed for channelized interface at the interface hierarchy, follow these steps:

To specify the port speed, in the [edit interface interface-name hierarchy level, configure the speed value using the set speed (10g | 25g | 40g | 50g | 100g | 400g) command.
```
[edit interfaces et-1/0/3]
user@host# set speed 100g
```
To configure the speed for a group of ports, in the [edit wildcard range interface interface-name hierarchy level, configure the speed value using the set speed (10g | 25g | 40g | 50g | 100g | 400g) command.
```
[edit wildcard range set interfaces et-1/0/[7-12]
user@host# set speed 100g
```
To specify the number of interfaces you want to configure per port.
```
[edit interfaces et-2/0/3]
user@host# set number-of-sub-ports 4
```
Note:
In this example, in Step 1 and Step 2, you configure 4x100GE channelized interfaces.
To control the number of interfaces created on a physical port, use the unused statement.
```
[edit interfaces et-2/0/4]
user@host# set unused 
```

Verify the configuration.

content_copy zoom_out_map
[edit interfaces]
user@host# 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;
}

Commit the configuration.
```
[edit interfaces et-1/0/3]
user@host# commit
```
