To view and set status of a network interface, you can use `mii-tool` utility.

To view status of interfaces:

```
mii-tool

```

simply displays status of all interfaces.

Sample output is as below:eth0:

```
negotiated 100baseTx-FD, link ok
eth1: 100 Mbit, half duplex, no link

```

To set one interface to a value by using force, you can usethe command below:

```
mii-tool -F <media> <device>

```

where _media_ is one of 100baseT4, 100baseTx-FD,100baseTx-HD, 10baseT-FD, 10baseT-HD and _device_ is the interface name such as _eth0_ or _eth1_

Example:

```
mii-tool -F 100baseTx-FD eth0

```

sets interface eth0 to 100baseTx-FD without autonegotiation.
