1、查看AIX系統(tǒng)網(wǎng)卡信息：

[root@aix211 /]#lsdev |grep et?

1 2 3 4 5 6 7 8 9

en0????????Available?1L-08?????????Standard?Ethernet?Network?Interface en1????????Available?14-08?????????Standard?Ethernet?Network?Interface en2????????Defined???1D-08?????????Standard?Ethernet?Network?Interface ent0???????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?Interface et1????????Defined???14-08?????????IEEE?802.3?Ethernet?Network?Interface et2????????Defined???1D-08?????????IEEE?802.3?Ethernet?Network?Interface

由此可以看出：

ent1之類的是物理網(wǎng)卡的設(shè)備名，en0或是et0是網(wǎng)絡(luò)接口名(邏輯上的)，enx(x是一個(gè)數(shù)字，代表第幾塊網(wǎng)卡)是標(biāo)準(zhǔn)以太網(wǎng)接口，et0是IEEE 802.3以太網(wǎng)接口。

en0是Ethernet II protocal interface

et0是802.3 protocal interface?

ent0是Hardware device interface

2、查看網(wǎng)卡屬性：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

3、查看網(wǎng)卡配置:

1 2 3 4 5 6 7 8 9 10 11 12 13 14

[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(wǎng)卡是否是插在PCI接口上的

[root@aix211 /]#lsslot -c pci

1 2 3 4 5 6 7

#?Slot??????Description?????????????????????????Device(s) U0.1-P2-I1??PCI-X?capable,?64?bit,?133MHz?slot??Empty??? U0.1-P2-I2??PCI-X?capable,?64?bit,?133MHz?slot??Empty???

U0.1-P2-I6??PCI-X?capable,?64?bit,?133MHz?slot??Empty

[root@aix211 /]#lscfg -vpl ent2

1 2 3 4 5 6 7 8 9 10

?ent2?????????????U0.1-P2-I5/E1??10/100?Mbps?Ethernet?PCI?Adapter?II?(1410ff01) ??????10/100?Mbps?Ethernet?PCI?Adapter?II: ????????Part?Number.................09P5023 ????????FRU?Number..................09P5023 ????????EC?Level....................H10971A ????????Manufacture?ID..............YL1021 ????????Network?Address.............000255AF8DAD ????????ROM?Level.(alterable).......SCU004 ????????Product?Specific.(Z0).......A5204205 ????????Hardware?Location?Code......U0.1-P2-I5/E1

--- 可以看出，ent2是插在pci插槽上

物理設(shè)備和邏輯設(shè)備

1、物理設(shè)備是指以某種方式與計(jì)算機(jī)系統(tǒng)相連的實(shí)際硬件。例如顯示器、終端、磁帶機(jī)等。

2、邏輯設(shè)備是用戶或應(yīng)用程序訪問(wèn)物理設(shè)備的界面，用戶或應(yīng)用程序通過(guò)邏輯設(shè)備來(lái)訪問(wèn)物理設(shè)備。

3、在很多情況下，一個(gè)物理設(shè)備會(huì)對(duì)應(yīng)多個(gè)邏輯設(shè)備
