交換機(jī)上的DHCP+vlan多IP網(wǎng)段配置

1、-. z.有關(guān)交換機(jī)為vlan指定地址的DHCP的配置在三層交換交換上劃分多個(gè)VlAN，并為Vlan指定不同的網(wǎng)段的配置。此處講解的是多個(gè)iP網(wǎng)段的DHCP不同配置方法，根本配置此處略。第一種情況例子：如圖實(shí)施步驟：配置dns如圖：2、創(chuàng)立VLANSwitch#conf tEnter configuration mands, one per line.

6、ndSwitch(config)ip dhcp e*cluded-address 192.168.10.100 192.168.10.254 排除DHCP分配的地址圍Switch(config)ip dhcp e*cluded-address 192.168.20.100 192.168.20.254 Switch(config)ip dhcp e*cluded-address 192.168.30.100 192.168.30.254 驗(yàn)證、查看主機(jī)獲取情況如圖、查看3主機(jī)獲取情況如圖第二、三種情況此兩種情況合并一起講解了。具體配置：如圖連接設(shè)備在兩層交換機(jī)配置VLAN，步驟如上。配置效勞器

7、的IP地址：如下列圖配置三層交換機(jī)：配置文件如圖!ip dhcp pool vlan10 default-router 192.168.10.254 此處為vlan10的IP地址ip dhcp pool vlan20default-router 192.168.20.254 此處為vlan20的IP地址ip dhcp pool vlan30dns-server 192.168.1.250 此處為vlan30的IP地址啟動(dòng)端口三層功能具體配置文件interface FastEthernet0/22 此接口為vlan10自動(dòng)獲取IP地址啟用路由no switchportip address 192.168.10.254 255.255.255.0 此為vlan10的IP地址相當(dāng)以網(wǎng)關(guān)interface FastEthernet0/23 此接口為vlan10自動(dòng)獲取IP地址啟用路由 no switchportip address 192.168.30.254 255.255.255.0 此為Vlan30的IP地址相當(dāng)以網(wǎng)關(guān)interface FastEthernet0/24 此接口
