| 9 | !!DESCRIPTION | ||
| 10 | |||
| 3 | CraigBox | 11 | This utility checks or sets the status of a network interface's Media Independent Interface (MII) unit. Most fast ethernet adapters use an MII to autonegotiate link speed and duplex setting. |
| 1 | perry | 12 | |
| 3 | CraigBox | 13 | Most intelligent network devices use an autonegotiation protocol to communicate what media technologies they support, and then select the fastest mutually supported media technology. The __-A__ or __--advertise__ options can be used to tell the MII to only advertise a subset of its capabilities. Some passive devices, such as single-speed hubs, are unable to autonegotiate. To handle such devices, the MII protocol also allows for establishing a link by simply detecting either a 10baseT or 100baseT link beat. The __-F__ or __--force__ options can be used to force the MII to operate in one mode, instead of autonegotiating. The __-A__ and __-F__ options are mutually exclusive. |
| 1 | perry | 14 | |
| 3 | CraigBox | 15 | The default short output reports the negotiated link speed and link status for each interface. If an interface or interfaces are not specified on the command line, then __mii-tool__ will check any available interfaces from __eth0__ through __eth7__. |

| 17 | !!OPTIONS | ||
| 18 | |||
| 3 | CraigBox | 19 | ; __-v__, __--verbose__ : Display more detailed MII status information. If used twice, also display raw MII register contents. |
| 20 | ; __-V__, __--version__ : Display program version information. | ||
| 21 | ; __-R__, __--reset__ : Reset the MII to its default configuration. | ||
| 22 | ; __-r__, __--restart__ : Restart autonegotiation. | ||
| 23 | ; __-w__, __--watch__ : Watch interface(s) and report changes in link status. The MII interfaces are polled at one second intervals. | ||
| 24 | ; __-l__, __--log__ : Used with __-w__, records link status changes in the system log instead of printing on standard output. | ||
| 25 | ; __-F__ ''media'', __--force=__''media'' : Disable autonegotiation, and force the MII to either__100baseTx-FD__, __100baseTx-HD__, __10baseT-FD__, or __10baseT-HD__ operation. | ||
| 26 | ; __-A__ ''media,...'', __--advertise=__''media,...'' : Enable and restart autonegotiation, and advertise only the specified media technologies. Multiple technologies should | ||
| 27 | be separated by commas. Valid media are __100baseT4__, __100baseTx-FD__, __100baseTx-HD__, __10baseT-FD__, and __10baseT-HD__. | ||
