H3C三层交换机作为DHCP服务器，那么其中DHCP服务器要怎么配置呢?下面yjbys小编为大家分享最新交换机作为DHCP服务器的配置实例，希望对同学们学习DHCP服务器配置有所帮助!
DHCP采样UDP链接方式，服务器端口为67，客户机端口为68.
实验环境(H3C ENSP)
一、配置要点
a：在路由器上配置DHCPserver
第一步：(系统视图)开启DHCP ：DHCP enable
第二步：(进入接口视图)为与客户端相连的`端口配置ip地址
第三步：(系统视图)建立DHCP地址池 :ip pool aaa
第四步：(pool模式下)配置network网段、Gateway-list网关、
dns-list DNS服务器地址、excluded-ip-address需要排除的ip地址
第五步：进入接口模式，在接口中启动DHCP动态分配：dhcp select globle
第六步：将客户端的dhcp启动即可
实例：
路由器配置：
#
sysname Huawei
#
dhcp enable
#
ip pool aaa
gateway-list
network mask
excluded-ip-address
dns-list
#
aaa
authentication-scheme default
authorization-scheme default
accounting-scheme default
domain default
domain default_admin
local-user admin password cipher OOCM4m($F4ajUn1vMEIBNUw#
local-user admin service-type http
#
firewall zone Local
priority 16
#
interface Ethernet0/0/0
ip address
dhcp select global
#
interface Ethernet0/0/1
#

#

#
interface Serial0/0/2

#
interface Serial0/0/3

#
interface GigabitEthernet0/0/0
#
interface GigabitEthernet0/0/1
#
interface GigabitEthernet0/0/2
#
interface GigabitEthernet0/0/3
#
wlan
#
interface NULL0
#
user-interface con 0
user-interface vty 0 4
user-interface vty 16 20
#
return
b：在三层交换机中为不同vlan配置不同DHCPserver
第一步：在三层交换机上建好vlan并分配好端口
第二步：(系统视图)开启DHCP ：DHCP enable
第三步：为每一个vlan都建立一个相应的DHCP地址池(命名可以随意)
第四步：为每一个地址池配置好自己相应vlan的network网段、Gateway-list网关、
dns-list DNS服务器地址、excluded-ip-address需要排除的ip地址
第五步：进入每一个vlan接口，先配置好各自的ip地址，然后在启动DHCP动态分配：dhcp select globle
第六步：将客户端的dhcp启动即可
