———–总体规划设计
1.思科核心交换g 7/8————连接———-华三 g1/0/19口
2.两端配置trunk模式
3.华三创建vlan,access模式
4.地下室，1-8，vlan41;9-16,vlan42。
————-思科核心交换4507R端配置

Switch#conf t
——————-第一步：创建vlan,并进入vlan虚接口添加各自IP地址，此IP地址就是DHCP的网关地址。
Switch(config)#vlan 41 –创建vlan 41/20
Switch(config)#vlan 42
—-三层交换机已开启路由，没做此步骤；Switch(config)#ip routing –开启路由
Switch(config)#int vlan 41 –进入vlan，设置对应IP/子网
Switch(config-if)#ip add 192.168.41.1 255.255.255.0
Switch(config-if)#no shut
Switch(config-if)#int vlan 42
Switch(config-if)#ip add 192.168.42.1 255.255.255.0
Switch(config-if)#no shut
————————————————
—————-第二步：创建vlan41的地址池和vlan 42的地址池,创建DHCP地址池；
Switch(config)#ip dhcp vlan 41
network 192.168.41.0 255.255.255.0
default-router 192.168.41.1
dns-server 172.16.2.6 172.16.2.10
exit
Switch(config)#ip dhcp vlan 42
network 192.168.42.0 255.255.255.0
default-router 192.168.42.1
dns-server 172.16.2.6 172.16.2.10
exit
————————–第三步：将三层交换机的级联口设置为trunk模式，并允许vlan 41和42通过，默认是允许所有通过。
interface g 7/8
—–没做此步骤操作switchport trunk encapsulation dot1q //封装协议
switchport mode trunk
switchport trunk allowed vlan 41-42 //允许通过的vlan标签，必须是一个范围，不然，后面的会覆盖前面的，导致后面的vlan可以获得IP，前面的获得失败。
