华为交换机上配置基于地址池的DHCP服务器

操作步骤
全局启动DHCP服务。
<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
[Huawei]dhcp enable   
创建地址池并配置相关属性。 
# 配置IP地址池10的属性（地址池范围、DNS地址、出口网关和地址池租期）。
[Huawei]ip pool 10
Info:It's successful to create an IP address pool.
[Huawei-ip-pool-10]network 192.168.10.0 mask 255.255.255.0
[Huawei-ip-pool-10]dns-list 202.102.224.68
[Huawei-ip-pool-10]gateway-list 192.168.10.1
[Huawei-ip-pool-10]lease day 10
[Huawei-ip-pool-10]quit

# 配置IP地址池20的属性（地址池范围、DNS地址、出口网关、NetBOIS地址和地址池租期） www.it165.net
[Huawei]ip pool 10
Info:It's successful to create an IP address pool.
[Huawei-ip-pool-20]network 192.168.20.0 mask 255.255.255.0
[Huawei-ip-pool-20]dns-list 202.102.224.68
[Huawei-ip-pool-20]gateway-list 192.168.20.1
[Huawei-ip-pool-20]lease day 10
[Huawei-ip-pool-20]quit

配置VLANIF接口下地址分配方式。 
# 配置接口GE0/0/1和GE0/0/2分别加入相应的VLAN。
[Huawei]vlan batch 10 20
[Huawei]interface GigabitEthernet 0/0/1
[Huawei-GigabitEthernet0/0/1]port link-type access
[Huawei-GigabitEthernet0/0/1]port default vlan 10
[Huawei-GigabitEthernet0/0/1]quit
[Huawei]interface GigabitEthernet 0/0/2
[Huawei-GigabitEthernet0/0/2]port link-type access
[Huawei-GigabitEthernet0/0/2]port default vlan 20
[Huawei-GigabitEthernet0/0/2]quit

# 配置VLANIF10接口下的客户端从全局地址池中获取IP地址。
[Huawei]interface Vlanif 10
[Huawei-Vlanif10]ip address 192.168.10.1 24
[Huawei-Vlanif10]dhcp select global
[Huawei-Vlanif10]quit

# 配置VLANIF20接口下的客户端从全局地址池中获取IP地址。
[Huawei]interface Vlanif 20
[Huawei-Vlanif20]ip add 192.168.20.1 24
[Huawei-Vlanif20]dhcp select global
[Huawei-Vlanif20]quit

验证配置结果。 
在Switch上使用display ip pool命令用来查看IP地址池配置情况。
[Huawei]display ip pool
