我是在VirtualBox中安裝Solaris 10，原本設定一個網卡，後來因為測試需要，
所以又增加了兩個網卡，開機後只有原來的網卡可以使用，新增的網卡全都無法使用。
bash-3.00# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
e1000g0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 10.10.1.100 netmask ffffff00 broadcast 10.10.1.255
ether 8:0:27:4:b7:5b
先檢查有沒有抓到網卡，底下顯示有識別到新的網卡
bash-3.00# dmesg |grep mac

利用dladm查詢網卡的狀態，三張網卡都是up。
bash-3.00# dladm show-dev
e1000g0 link: up speed: 1000 Mbps duplex: full
e1000g1 link: up speed: 1000 Mbps duplex: full
e1000g2 link: up speed: 1000 Mbps duplex: full
直接加入e1000g1
bash-3.00# ifconfig e1000g1 plumb

上面看的出來新的網卡並沒有IP，接著可以直接設定IP給它，不過開機後就會消失了。
bash-3.00# ifconfig e1000g1 10.10.1.101 netmask 255.255.255.0
增加IP的設定到/etc內，檔案名稱為hostname.<介面名>，例如：e1000g0 --> hostname.e1000g0
新增文字檔hostname.e1000g1，並加入IP如下：
10.10.1.101
再新增文字檔hostname.e1000g2，並加入IP如下：
10.10.1.102
這樣重開機後就不用重設IP了
所以又增加了兩個網卡，開機後只有原來的網卡可以使用，新增的網卡全都無法使用。
