ifconfig 與 ip 指令的替代關係

ifconfig
--------

• 看 ip，直接下不用帶參數

eth0      Link encap:Ethernet  HWaddr 08:00:27:83:0B:8D
          inet addr:10.0.2.15  Bcast:10.0.2.255  Mask:255.255.255.0

• 看封包狀況，直接看，不用帶參數

          RX packets:45 errors:0 dropped:0 overruns:0 frame:0
          TX packets:39 errors:0 dropped:0 overruns:0 carrier:0

• 設定臨時 IP   

ifconfig eth0:0 192.168.56.201/24



ip
-------

• 看 ip，參數 address   

[root@localhost ~]# ip address
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 08:00:27:83:0b:8d brd ff:ff:ff:ff:ff:ff
    inet 10.0.2.15/24 brd 10.0.2.255 scope global eth0

• 看封包狀況，用參數 -s link

    RX: bytes  packets  errors  dropped overrun mcast  
    9626       92       0       0       0       0    

• 設定臨時 IP   

ip address add 192.168.56.201/24  dev eth0 label eth0:0
