在思科三层交换机DHCP的基本配置
1、修改三层交换机名为DHCP
DHCP#
2、显示vlan 并创建vlan 10 vlan 20 vlan 30 vlan 40
DHCP#VLAN Database
DHCP(vlan)#vlan 10
VLAN 10 added:
Name: VLAN0010
DHCP(vlan)#vlan 20
VLAN 20 added:
Name: VLAN0020
DHCP(vlan)#vlan 30
VLAN 30 added:
Name: VLAN0030
DHCP(vlan)#vlan 40
VLAN 40 added:
Name: VLAN0040
DHCP(vlan)#exit
APPLY completed.
Exiting....
3、配置思科三层交换 启用路由 把
f0/1放入vlan10
f0/2放入vlan20
f0/3放入vlan30
f0/4放入vlan40
DHCP#conf t
Enter configuration commands, one per line. End with CNTL/Z.
DHCP(config)#ip routing
DHCP(config)#int f0/1
DHCP(config-if)#switchport access vlan 10
DHCP(config-if)#int f0/2
DHCP(config-if)#switchport access vlan 20
DHCP(config-if)#int f0/3
DHCP(config-if)#switchport access vlan 30
DHCP(config-if)#int f0/4
DHCP(config-if)#switchport access vlan 40
DHCP(config-if)#exit
DHCP(config)#int vlan 10
DHCP(config-if)#ip address 10.0.0.10 255.0.0.0
DHCP(config-if)#no sh
DHCP(config-if)#int vlan 20
DHCP(config-if)#ip address 20.0.0.10 255.0.0.0
DHCP(config-if)#no sh
DHCP(config-if)#int vlan 30
DHCP(config-if)#ip address 30.0.0.10 255.0.0.0
DHCP(config-if)#no sh
DHCP(config-if)#int vlan 40
DHCP(config-if)#ip address 40.0.0.10 255.0.0.0
DHCP(config-if)#no sh
DHCP(config-if)#exit
4、配置dhcp ,配置排除的IP地址
DHCP(config)#ip dhcp pool v1
DHCP(dhcp-config)#network 10.0.0.0
DHCP(dhcp-config)#default-router 10.0.0.10
DHCP(dhcp-config)#dns-server 202.106.0.20
DHCP(dhcp-config)#exit
DHCP(config)#ip dhcp excluded-address 10.0.0.1 10.0.0.20
DHCP(config)#ip dhcp pool v2
DHCP(dhcp-config)#network 20.0.0.0
DHCP(dhcp-config)#default-router 20.0.0.10
DHCP(dhcp-config)#dns
DHCP(dhcp-config)#dns-server 202.106.0.20
DHCP(dhcp-config)#exit
DHCP(config)#ip dhcp excluded-address 20.0.0.1 20.0.0.20
DHCP(config)#ip dhcp pool v3
DHCP(dhcp-config)#network 30.0.0.0
DHCP(dhcp-config)#default-router 30.0.0.10
DHCP(dhcp-config)#dns-server 202.106.0.20
DHCP(dhcp-config)#exit
DHCP(config)#ip dhcp excluded-address 30.0.0.1 30.0.0.20
DHCP(config)#ip dhcp pool v4
DHCP(dhcp-config)#network 40.0.0.0
DHCP(dhcp-config)#default-router 40.0.0.10
DHCP(dhcp-config)#dns-server 202.106.0.20
DHCP(dhcp-config)#exit
DHCP(config)#ip dhcp excluded-address 40.0.0.1 40.0.0.20
DHCP(config)#exit
DHCP#sh ip int br
