For replacement check \fBethtool\fB. + +.SH DESCRIPTION +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. +.PP +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 \fB\-A\fR or +\fB\-\-advertise\fR 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 \fB\-F\fR +or \fB\-\-force\fR options can be used to force the MII to operate in +one mode, instead of autonegotiating. The \fB\-A\fR and \fB\-F\fR +options are mutually exclusive. +.PP +The default short output reports the negotiated link speed and link +status for each interface. +.SH OPTIONS +.TP +\fB\-v\fR, \fB\-\-verbose\fR +Display more detailed MII status information. If used twice, also +display raw MII register contents. +.br +\fBAlert:\fR If used three times, will force reading all MII +registers, including non standard ones. It's not guaranteed any +valid answer from PHY while PHY communication can even hang. +With driver e1000e will fail while reading register 0x07. +.TP +\fB\-V\fR, \fB\-\-version\fR +Display program version information. +.TP +\fB\-R\fR, \fB\-\-reset\fR +Reset the MII to its default configuration. +.TP +\fB\-r\fR, \fB\-\-restart\fR +Restart autonegotiation. +.TP +\fB\-w\fR, \fB\-\-watch\fR +Watch interface(s) and report changes in link status. The MII +interfaces are polled at one second intervals. +.TP +\fB\-l\fR, \fB\-\-log\fR +Used with \fB\-w\fR, records link status changes in the system log +instead of printing on standard output. +.TP +\fB\-F\fI media\fR, \fB\-\-force=\fImedia\fR +Disable autonegotiation, and force the MII to either \fB100baseTx-FD\fR, +\fB100baseTx-HD\fR, \fB10baseT-FD\fR, or \fB10baseT-HD\fR operation. +.TP +\fB\-A\fI media,...\fR, \fB\-\-advertise=\fImedia,...\fR +Enable and restart autonegotiation, and advertise only the specified +media technologies.
