华为S7706交换机设置 DHCP

1.登陆S7706核心交换机后

1.建立新的VLAN
vlan 156
vlan 157

2.为VLAN 156 VLAN157分别设置DHCP的POOL（也就是需要分配的地址）

ip pool vlan156
 gateway-list 10.10.156.1
 network 10.10.156.0 mask 255.255.255.0
 excluded-ip-address 10.10.156.2 10.10.156.50
 excluded-ip-address 10.10.156.249 10.10.156.254
 lease day 0 hour 23 minute 0
 dns-list 202.106.0.20 114.114.114.114

 ip pool vlan157
 gateway-list 10.10.157.1
 network 10.10.157.0 mask 255.255.255.0
 excluded-ip-address 10.10.157.2 10.10.157.50
 excluded-ip-address 10.10.157.249 10.10.157.254
 lease day 0 hour 23 minute 0
 dns-list 202.106.0.20 114.114.114.114
 
 
 3.设置vlan156 VLAN157的网关和启用DHCP服务
 
interface Vlanif156
 ip address 10.10.156.1 255.255.255.0
 dhcp select global
 

 
 interface Vlanif157
 ip address 10.10.157.1 255.255.255.0
 dhcp select global

2.登陆5720s接入交换机

1.设置上联端口为TRUK（我的上联口是GigabitEthernet0/0/49）

interface GigabitEthernet0/0/49
 port link-type trunk
 port trunk allow-pass vlan 2 to 4094

####################
思科交换机命令
interface GigabitEthernet0/49
 switchport mode trunk
####################

2.建立vlan
vlan 156
vlan 157

3.将端口加入vlan
interface GigabitEthernet0/0/45
 port link-type access
 port default vlan 156


##############
思科交换机命令
interface FastEthernet0/45
 switchport access vlan 156
 switchport mode access

快速端口
 spanning-tree portfast
