◆◆實驗拓撲◆◆

◆◆實驗需求◆◆

1、C1與C3屬于vlan10，C2與C4屬于vlan20

2、SW1與SW2之間使用LACP模式鏈路捆綁，活動接口為2個

3、SW1與R1之間進行鏈路捆綁

4、VLAN 10 與 VLAN 20 通過DHCP自動獲取IP地址

5、在R1上配置單臂路由使全網(wǎng)互通

vlan10 IP：192.168.10.0/24

vlan20 IP：192.168.20.0/24

SW1配置：

system-view //進入系統(tǒng)視圖

[SW1]vlan batch 10 20 //創(chuàng)建vlan

[SW1]inter e0/0/1 //進接口

[SW1-Ethernet0/0/1]port hybrid pvid vlan 10 //為進來的數(shù)據(jù)包加vlan10標簽

[SW1-Ethernet0/0/1]port hybrid untagged vlan 10 //將接口以untagged方式加入vlan10

[SW1-Ethernet0/0/1]quit

[SW1]inter e0/0/2

[SW1-Ethernet0/0/2]port hybrid pvid vlan 20

[SW1-Ethernet0/0/2]port hybrid untagged vlan 20

[SW1-Ethernet0/0/2]quit

[SW1]lacp priority 100 //配置系統(tǒng)優(yōu)先級為100

[SW1]inter eth-trunk 1 //進入eth-trunk 1

[SW1-Eth-Trunk1]mode lacp-static //設(shè)置為lacp模式

[SW1-Eth-Trunk1]max active-linknumber 2 //設(shè)置活動接口為2

[SW1-Eth-Trunk1]port hybrid tagged vlan 10 20 //將接口以tagged方式加入到vlan10和vlan20,設(shè)置中繼

[SW1-Eth-Trunk1]quit

[SW1]interface e0/0/10 //進接口

[SW1-Ethernet0/0/10]eth-trunk 1 //將接口加入eth-trunk

[SW1-Ethernet0/0/10]lacp priority 100 //設(shè)置接口優(yōu)先級為100，默認為32768

[SW1-Ethernet0/0/10]inter e0/0/11

[SW1-Ethernet0/0/11]eth-trunk 1

[SW1-Ethernet0/0/11]inter e0/0/12

[SW1-Ethernet0/0/12]eth-trunk 1

[SW1-Ethernet0/0/12]quit

[SW1]interface Eth-Trunk 2 //進入eth-trunk 2

[SW1-Eth-Trunk2]trunkport GigabitEthernet 0/0/1 0/0/2 //將接口加入到eth-trunk中

[SW1-Eth-Trunk2]port hybrid tagged vlan 10 20 //將接口以tagged方式加入到vlan10和vlan20

SW2配置:

system-view

[SW2]vlan batch 10 20

[SW2]inter e0/0/3

[SW2-Ethernet0/0/3]port hybrid pvid vlan 10

[SW2-Ethernet0/0/3]port hybrid untagged vlan 10

[SW2-Ethernet0/0/3]quit

[SW2]interface e0/0/4

[SW2-Ethernet0/0/4]port hybrid pvid vlan 20

[SW2-Ethernet0/0/4]port hybrid untagged vlan 20

[SW2-Ethernet0/0/4]quit

[SW2]interface Eth-trunk 1

[SW2-Eth-Trunk1]mode lacp-static

[SW2-Eth-Trunk1]max active-linknumber 2

[SW2-Eth-Trunk1]trunkport Ethernet 0/0/10 to 0/0/12

[SW2-Eth-Trunk1]port hybrid tagged vlan 10 20

通過display eth-trunk 1 查看端口信息，發(fā)現(xiàn)優(yōu)先級高的e0/0/10,e0/0/11接口被選中為活動接口優(yōu)先級低的未被

◆◆在SW1上關(guān)閉一個端口SW1◆◆

[SW1]interface e0/0/10

[SW1-Ethernet0/0/10]shutdown

會發(fā)現(xiàn)0/0/10接口關(guān)閉了以后 0/0/12接口自動補上了

R1配置：

system-view

[R1]dhcp enable

[R1]interface Eth-Trunk 1 //進入eth-trunk 1

[R1-Eth-Trunk1]undo portswitch //轉(zhuǎn)換三層口，默認eth-trunk是二層口路由是三層端口要把接口轉(zhuǎn)換成三層接口才可以捆綁

[R1-Eth-Trunk1]trunkport GigabitEthernet 0/0/1 0/0/2 //將接口加入eth-trunk

[R1]interface Eth-Trunk 1.10 //進入子接口

[R1-Eth-Trunk1.10]dot1q termination vid 10 //封裝dot1q，設(shè)置為vlan10的網(wǎng)關(guān)

[R1-Eth-Trunk1.10]ip address 192.168.10.1 24 //配置接口IP

[R1-Eth-Trunk1.10]arp broadcast enable //開啟ARP廣播

[R1-Eth-Trunk1.10]dhcp select interface //采用接口地址池的DHCP功能

[R1-Eth-Trunk1.10]inter eth-trunk 1.20

[R1-Eth-Trunk1.20]dot ter vid 20

[R1-Eth-Trunk1.20]ip add 192.168.20.1 24

[R1-Eth-Trunk1.20]a b e

[R1-Eth-Trunk1.20]dhcp sel int

用PC自動獲取DHCP

C2獲取

C3獲取

C4獲取

C1去測試，全網(wǎng)互通
