配置DHCP交换机服务
[DHCP]dhcp enable #打开dhcp功能
[DHCP]vlan batch 10 20 #创建两个vlan vlan 10和 vlan 20
[DHCP]ip pool vlan10 #t添加一个名为vlan10的地址池
[DHCP-ip-pool-vlan10]gateway-list 172.16.100.254 #配置网关
[DHCP-ip-pool-vlan10]network 172.16.100.0 mask 255.255.255.0 #配置地址段
[DHCP-ip-pool-vlan10]excluded-ip-address 172.16.100.1 172.16.100.100 #配置IP排除范围
[DHCP-ip-pool-vlan10]lease day 5 #配置dhcp租约有效期为5天
[DHCP-ip-pool-vlan10]dns-list 223.5.5.5 #配置DNS
[DHCP]ip pool vlan20
[DHCP-ip-pool-vlan20]gateway-list 172.16.110.254
[DHCP-ip-pool-vlan20]lease day 5
[DHCP-ip-pool-vlan20]dns-list 180.76.76.76
分配vlanif10接口
[DHCP]interface Vlanif10 #进入vlanif10接口
[DHCP-Vlanif10]ip address 172.16.100.254 255.255.255.0 #配置接口IP
[DHCP-Vlanif10]dhcp select global #
[DHCP-Vlanif10]quit
[DHCP]interface Vlanif20
[DHCP-Vlanif20]ip address 172.16.110.254 255.255.255.0
[DHCP-Vlanif20]dhcp select global
[DHCP-Vlanif20]quit
给两个部门的dhcp配置trunk
[DHCP]interface GigabitEthernet 0/0/1
[DHCP-GigabitEthernet0/0/1]port link-type trunk
[DHCP-GigabitEthernet0/0/1]port trunk allow-pass vlan 10
[DHCP-GigabitEthernet0/0/1]quit
[DHCP]interface GigabitEthernet 0/0/2
[DHCP-GigabitEthernet0/0/2]port link-type trunk
[DHCP-GigabitEthernet0/0/2]port trunk allow-pass vlan 20
配置接入层交换机
[SW2-dev]dhcp enable #打开dhcp功能
[SW2-dev]vlan batch 10 #创建vlan10
[SW2-dev]interface Ethernet 0/0/1 进入接口
[SW2-dev-Ethernet0/0/1]port link-type trunk 配置接口为trunk
[SW2-dev-Ethernet0/0/1]port trunk allow-pass vlan 10 #配置允许vlan10可以通过
[SW2-dev-Ethernet0/0/1]quit
[SW2-dev]interface Ethernet 0/0/2
[SW2-dev-Ethernet0/0/2]port link-type access #配置接口类型为access
[SW2-dev-Ethernet0/0/2]port default vlan 10 #配置接口属于vlan10
同理，运维部门的交换机配置同上。
