现在我们利用华为S5700交换机配置一个DHCP服务器

拓扑图如下

 

操作步骤

  1. 全局启动DHCP服务。
    <Huawei>system-view
    Enter system view, return user view with Ctrl+Z.
    [Huawei]dhcp enable    
  2. 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

  3. # 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)
    [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 

  4. 配置VLANIF接口下地址分配方式。 

    # 配置接口GE0/0/1GE0/0/2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

  5. # 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 

  6. 验证配置结果。 

    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 
      -----------------------------------------------------------------------
      Pool-name      : 10
      Pool-No        : 0
      Position       : Local           Status           : Unlocked
      Gateway-0      : 192.168.10.1   
      Mask           : 255.255.255.0
      ××× instance   : --

    -----------------------------------------------------------------------
      Pool-name      : 20
      Pool-No        : 1
      Position       : Local           Status           : Unlocked
      Gateway-0      : 192.168.20.1   
      Mask           : 255.255.255.0
      ××× instance   : --
      IP address Statistic
        Total       :506  
        Used        :0          Idle        :506  
        Expired     :0          Conflict    :0          Disable   :0    
    [Huawei]
  7. 在客户端上验证是否成功
