Solarisのデータリンク確認コマンド

SolarisのNICをDuplex Fullにしたり、100M固定化するには大抵nddコマンドを使います(ドライバによって異なるのでドライバのmanページを見るのが確実)。

実際の動作状態をみるにはdladmコマンドを使います。

# dladm show-dev
hme0            link: unknown   speed: 100   Mbps       duplex: full
qfe0            link: unknown   speed: 0     Mbps       duplex: unknown
qfe1            link: unknown   speed: 0     Mbps       duplex: unknown
qfe2            link: unknown   speed: 0     Mbps       duplex: unknown
qfe3            link: unknown   speed: 0     Mbps       duplex: unknown

# dladm show-link
hme0            type: legacy    mtu: 1500       device: hme0
qfe0            type: legacy    mtu: 1500       device: qfe0
qfe1            type: legacy    mtu: 1500       device: qfe1
qfe2            type: legacy    mtu: 1500       device: qfe2
qfe3            type: legacy    mtu: 1500       device: qfe3

上のhme0にはndd等で何か設定したわけではないので、実際の動作状態が表示されていることになります。

でも、Solaris 10からはmanページがなくなってます 😕
