這裡我們可以看到ent0 和ent1 是在一個C4插槽下兩個介面，ent2，ent3是在插槽C5上的兩個介面。
下面是真是740 後面拓撲圖
可以確定的 我介面網線的介面為 黃色介面 C6-T3，C4-T1，C5-T1

那我們可以確定en0
inet 12.12.12.1 netmask 0xffffff00 broadcast 12.12.12.255
inet 169.254.19.124 netmask 0xffff8000 broadcast 169.254.127.255
是在ent0介面上也即是在 c4-t1上
En2
inet 172.16.160.15 netmask 0xffffff00 broadcast 172.16.160.255
inet 172.16.160.10 netmask 0xffffff00 broadcast 172.16.160.255
tcp_sendspace 65536 tcp_recvspace 65536 rfc1323
是在ent2介面上，也就是在c5-t1上
那麼我還有個en6 的ip 不知道是在哪個網路卡介面上，由於我剩下最後一根網線是接在C6-T3上的，那麼很明顯
en6:
flags=1e080863,c0
inet 13.13.13.1 netmask 0xffffff00 broadcast 13.13.13.255
inet 169.254.254.158 netmask 0xffff8000 broadcast 169.254.255.255
這個ip是在C6-T3上
我們可以證實一下

剩下的只有ent4，ent5，ent6，ent7 這些介面顯然在c6槽位從上到下 四個介面
先查一下ent4

由於系統預設的en6 和ent6 對應的，所有我們可以確定en6 的ip在ent6上，這也是真是情況相符合。
