cisco的三層交換上怎麼給不同vlan配置不同的dhcp呀

1樓：匿名使用者

三層交換機的配置：

configure terminal

vlan 10

vlan 20

vlan 30 //建立vlan 10,20,30

inte***ce vlan 10

ip add 192.168.10.1 255.255.255.0 //vlan10的閘道器地址192.168.10.1

exit

ip dhcp excluded-address 192.168.10.1 //將閘道器地址從地址池中剔除

ip dhcp pool vlan10 //配置dhcp地址池，名字vlan10

***work 192.168.10.0 255.255.255.0 //定義dhcp地址池的地址範圍

default-router 192.168.10.1 //定義該地址池的閘道器地址

dns-server 211.0.0.2 //配置dns伺服器

inte***ce vlan 20

ip add 192.168.20.1 255.255.255.0 //vlan20的閘道器地址192.168.20.1

exit

ip dhcp excluded-address 192.168.20.1 //將閘道器地址從地址池中剔除

ip dhcp pool vlan20 //配置dhcp地址池，名字vlan20

***work 192.168.20.0 255.255.255.0 //定義dhcp地址池的地址範圍

default-router 192.168.20.1 //定義該地址池的閘道器地址

dns-server 211.0.0.2 //配置dns伺服器

inte***ce vlan 30

ip add 192.168.30.1 255.255.255.0 //vlan30的閘道器地址192.168.30.1

exit

ip dhcp excluded-address 192.168.30.1 //將閘道器地址從地址池中剔除

ip dhcp pool vlan30 //配置dhcp地址池，名字vlan30

***work 192.168.30.0 255.255.255.0 //定義dhcp地址池的地址範圍

default-router 192.168.30.1 //定義該地址池的閘道器地址

dns-server 211.0.0.2 //配置dns伺服器

inte***ce f0/1 //假設f0/1連線一個二層交換機

switchport mode trunk //配置trunk模式

switchport trunk native vlan 10 //配置本徵vlan

exit //另一個埠配置類似

ip routing //開啟三層功能

其中連線三層交換機f0/1埠的二層交換機配置如：

conf t

vlan 10

vlan 20

vlan 30

inte***ce f0/1

switchport access vlan 10 //假設f0/1連線vlan10，其他幾個vlan埠配置類似

int f0/24 //假設f0/24連線三層交換機

switchport mode trunk

switchport trunk native vlan10 //配置本徵vlan，需要與三層交換機上的對應埠的本徵vlan一致

exit

//另一個交換機類似

//主機ip用自動獲取

2樓：

首先建立四個vlan，10、

20、30、40，10、20、30做不同的閘道器，40做dhcp伺服器閘道器，介面地址配置為10.130.100.

0/24,10.130.101.

0/24,10.130.102.

0/24,10.129.0.

1/24,dhcp伺服器可以配置地址10.129.0.

2/24，然後在vlan介面下面新增一條ip helper-address 10.129.0.

2就可以了，dhcp伺服器裡面建立三個作用域，分別是把三個網段的地址新增進去就可以了！

具體的地址怎麼安排分配就看你有多少臺pc，要怎麼來分了！

3樓：

可以用dhcp伺服器嗎？可以的話用iphelper就異常簡單了
