：在cisco 3745路由器上配置dhcp

NAT-SERVER# config t
NAT-SERVER(config)# ip dhcp pool F03
NAT-SERVER(dhcp-config)# network 192.168.103.0 255.255.255.0
NAT-SERVER(dhcp-config)# dns-server 211.98.2.4
NAT-SERVER(dhcp-config)# default-router 192.168.103.1
NAT-SERVER(dhcp-config)# exit
NAT-SERVER(config)#ip dhcp excluded-address 192.168.103.1 192.168.103.10 (保留IP地址段。不用于DHCP分配)

察看dhcp配置：
NAT-SERVER#show running-config
