AIX Study之--AIX網卡組態管理（ent0、en0、et0）
1、查看AIX系統網卡資訊:
[root@aix211 /]#lsdev |grep et 

en0        Available 1L-08         Standard Ethernet Network Interfaceen1        Available 14-08         Standard Ethernet Network Interfaceen2        Defined   1D-08         Standard Ethernet Network Interfaceent0       Available 1L-08         10/100 Mbps Ethernet PCI Adapter II (1410ff01)ent1       Available 14-08         10/100 Mbps Ethernet PCI Adapter II (1410ff01)ent2       Available 1D-08         10/100 Mbps Ethernet PCI Adapter II (1410ff01)et0        Defined   1L-08         IEEE 802.3 Ethernet Network Interfaceet1        Defined   14-08         IEEE 802.3 Ethernet Network Interfaceet2        Defined   1D-08         IEEE 802.3 Ethernet Network Interface

由此可以看出：

ent1之類的是物理網卡的裝置名稱，en0或是et0是網路介面名(邏輯上的)，enx(x是一個數字，代表第幾塊網卡)是標準乙太網路介面，et0是IEEE 802.3乙太網路介面。

en0是Ethernet II protocal interface

et0是802.3 protocal interface 

ent0是Hardware device interface

2、查看網卡屬性：

3、查看網卡配置:

[root@aix211 /]#lscfg -vpl en0[root@aix211 /]#lscfg -vpl et0[root@aix211 /]#lscfg -vpl ent0  ent0             U0.1-P1/E2  10/100 Mbps Ethernet PCI Adapter II (1410ff01)    10/100 Mbps Ethernet PCI Adapter II:        Network Address.............000255CF1406        ROM Level.(alterable).......SCU015        Product Specific.(Z0).......A5204205        Hardware Location Code......U0.1-P1/E2  PLATFORM SPECIFIC  Name:  ethernet    Node:  ethernet@1    Device Type:  network    Physical Location: U0.1-P1/E2

Physical Location的位置可以判斷網卡是否是插在PCI介面上的

--- 可以看出，ent2是插在pci插槽上
物理裝置和邏輯裝置

1、物理裝置是指以某種方式與電腦系統相連的實際硬體。例如顯示器、終端、磁帶機等。

2、邏輯裝置是使用者或應用程式訪問物理裝置的介面，使用者或應用程式通過邏輯裝置來訪問物理裝置。

3、在很多情況下，一個物理裝置會對應多個邏輯裝置

查看物理裝置：[root@aix211 /]#lsdev -Cc adapter

ent2    Available 1D-08    10/100 Mbps Ethernet PCI Adapter II (1410ff01)
fcs0    Available 1n-08    FC Adapter
