步骤：
第一步
首先打开SW1，配置它vlan信息
SW1#conf t
Enter configuration commands, one per line.
SW1#vlan database
SW1(vlan)#vlan 10 name ccna
VLAN 10 added:
Name: ccna
SW1(vlan)#vlan 20 name ccnp
VLAN 20 added:
Name: ccnp
SW1(vlan)#exit
APPLY completed.
Exiting....
SW1#conf t
Enter configuration commands, one per line.
SW1(config)#int f0/1
SW1(config-if)#switchport access vlan 10
SW1(config-if)#int f0/2
SW1(config-if)#switchport access vlan 20
SW1(config-if)#int f0/0
SW1(config-if)#switchport mode trunk
*Mar
第二步
对DHCPServer的配置
DHCPServer#conf t
Enter configuration commands, one per line.
DHCPServer(config)#int f0/0
DHCPServer(config-if)#no shutdown
*Mar
*Mar
DHCPServer(config-if)#int f0/0.10
DHCPServer(config-subif)#encapsulation dot1Q
10
DHCPServer(config-subif)#ip add 192.168.10.1 255.255.255.0
DHCPServer(config-subif)#int f0/0.20
DHCPServer(config-subif)#encapsulation dot1Q 20
DHCPServer(config-subif)#ip add 192.168.20.1 255.255.255.0
DHCPServer(config-subif)#exit
DHCPServer(config)#service dhcp
DHCPServer(config)#ip dhcp pool vlan_10
DHCPServer(dhcp-config)#network 192.168.10.0 /24
DHCPServer(dhcp-config)#dns-server 8.8.8.8
DHCPServer(dhcp-config)#lease 0 10 30
DHCPServer(dhcp-config)#default-router 192.168.10.1
DHCPServer(dhcp-config)#ip dhcp pool vlan_20
DHCPServer(dhcp-config)#network 192.168.20.0 /24
DHCPServer(dhcp-config)#dns-server 8.8.8.8
DHCPServer(dhcp-config)#lease 0 2
DHCPServer(dhcp-config)#default-router 192.168.20.1
DHCPServer(dhcp-config)#exit
DHCPServer(config)#ip dhcp excluded-address 192.168.10.1 192.168.10.10
DHCPServer(config)#ip dhcp excluded-address 192.168.20.1 192.168.20.6
DHCPServer(config)#end
DHCPServer#show ip dhcp pool
Pool vlan_10 :
Utilization mark (high/low)
Subnet size (first/next)
Total
addresses
Leased
addresses
Pending
event
1 subnet is currently in the pool :
Current index
192.168.10.1
Pool vlan_20 :
Utilization mark (high/low)
Subnet size (first/next)
Total
addresses
Leased
addresses
Pending
event
1 subnet is currently in the pool :
Current index
192.168.20.1
DHCPServer#
第三步
对PC1、PC2的配置
PC1#conf t
Enter configuration commands, one per line.
PC1(config)#no ip routing
PC1(config)#no ip do lo
PC1(config)#int f0/0
PC1(config-if)#ip add dhcp
PC1(config-if)#no shutdown
*Mar
*Mar
*Mar
PC1(config-if)#end
PC1#show ip int b
Interface
FastEthernet0/0
PC2
PC2#conf t
Enter configuration commands, one per line.
PC2(config)#no ip routing
PC2(config)#no ip do lo
PC2(config)#int f0/0
PC2(config-if)#ip add dhcp
PC2(config-if)#no shutdown
PC2(config-if)#end
*Mar
*Mar
*Mar
PC2#show ip int b
Interface
FastEthernet0/0
第四步
我们可以对它们之间能否通信进行测试
PC2#ping 192.168.20.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.20.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 20/231/1028 ms
PC2#ping 192.168.10.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.10.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 16/32/56 ms
PC2#ping 192.168.10.11
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.10.11, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 20/38/60 ms
PC2#
它们之间能通信，实验成
