Setting the Bandwidth Value for an Ethernet Interface

The current bandwidth value for an Ethernet interface can be set and communicated to higher-level protocols such as OSPF.

Enter the configure terminal command to access global configuration mode.
```
device# configure terminal
```

Enter the interface ethernet command to configure an Ethernet interface and enter interface configuration mode.
```
device(config)# interface ethernet 1/1/1
```

Enter the bandwidth command and specify a value to set the bandwidth value on the interface.
```
device(config-if-e1000-1/1/1)# bandwidth 2000
```

This example sets the bandwidth to 2000 kbps on a specific Ethernet interface.

device# configure terminal
device(config)# interface ethernet 1/1/1
device(config-if-e1000-1/1/1)# bandwidth 2000

The bandwidth specified in this example results in the following OSPF cost, assuming the auto-cost is 100:

OSPF cost is equal to ((100 * 1000) + (2000 - 1)/ 2000) = 50
