第十一期 小型企业自动分配IP地址和不同网段通信

实验目的：
1.DHCP自动分配地址
2.Vlan间通信
实验步骤：

1. 在两台二层交换机上创建vlan【sw1?vlan10 sw2?vlan20】并将三个端口加入相应的vlan中
   [sw1]vlan 10
   [sw1-vlan10]q
   [sw1-GigabitEthernet0/0/1]undo sh
   Info: Interface GigabitEthernet0/0/1 is not shutdown.
   [sw1-Ethernet0/0/1]port link-type acc//选择access模式
   [sw1-Ethernet0/0/1]port def vlan 10 //加入vlan10
   其他端口同理【sw2上只是把vlan10换成vlan20】
2. 配置三层交换机：
   创建vlan10、2
   将vlan10/20加入端口【access模式】
   配置vlanIP：
   [dhcp-Vlanif10]undo sh
   Info: Interface Vlanif10 is not shutdown.
   [dhcp-Vlanif10]
   [dhcp-Vlanif10]
   [dhcp-Vlanif10]ip add 192.168.10.254 255.255.255.0
   [dhcp-Vlanif20]ip add 192.168.20.254 255.255.255.0
   创建地址池:
   [dhcp]ip pool vlan-10
   Info:It‘s successful to create an IP address pool.
   [dhcp-ip-pool-vlan-10]network 192.168.10.0 mask 255.255.255.0
   [dhcp-ip-pool-vlan-10]gateway-list 192.168.10.254
   [dhcp]ip pool vlan-20
   Info:It‘s successful to create an IP address pool.
   [dhcp-ip-pool-vlan-20]network 192.168.20.0 mask 255.255.255.0
   [dhcp-ip-pool-vlan-20]gateway-list 192.168.20.254
   开启DHCP功能，端口开启DHCP全局：
   [dhcp]dhcp enable
   Info: The operation may take a few seconds. Please wait for a moment.done.
   [dhcp-Vlanif10]dhcp select global
   [dhcp-Vlanif20]dhcp select global
   配置完成
   3.验证、测试、保存
