리눅스 mii-tool 매뉴얼

mii-tool은 랜카드의 상태를 보는 툴인데..

광은 볼 수 가 없습니다.

광은 ethtool 로 봐야 합니다.

NAME
       mii-tool - view, manipulate media-independent interface status

SYNOPSIS
       mii-tool  [-v, --verbose] [-V, --version] [-R, --reset] [-r, --restart] [-w, --watch] [-l, --log] [-A, --adver-
       tise=media,...]  [-F, --force=media] [interface ...]

NOTE
       This program is obsolete. Valid media are only 100baseT4, 100baseTx-FD,100baseTx-HD, 10baseT-FD and  10baseT-HD
       ethernet cards. For replacement check ethtool.

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.

       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 exclu-
       sive.

       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.

OPTIONS
       -v, --verbose
              Display more detailed MII status information.  If used twice, also display raw MII register contents.

       -V, --version
              Display program version information.

       -R, --reset
              Reset the MII to its default configuration.

       -r, --restart
              Restart autonegotiation.

       -w, --watch
              Watch interface(s) and report changes in link status.  The MII  interfaces  are  polled  at  one  second
              intervals.

       -l, --log
              Used with -w, records link status changes in the system log instead of printing on standard output.

       -F media, --force=media
              Disable autonegotiation, and force the MII to either 100baseTx-FD, 100baseTx-HD, 10baseT-FD, or 10baseT-
              HD operation.

       -A media,..., --advertise=media,...
              Enable and restart autonegotiation, and advertise only the specified media technologies.  Multiple tech-
              nologies should be separated by commas.  Valid media are 100baseT4, 100baseTx-FD, 100baseTx-HD, 10baseT-
              FD, and 10baseT-HD.
