配置接口的主从IP地址示例

组网需求

图1所示,Switch上只有一个空闲以太网接口10GE1/0/1,但该局域网中的计算机分别属于2个不同的网段172.16.1.0/24和172.16.2.0/24,要求通过Switch可以实现一个接口接入两个不同的网段。

配置思路

配置主从IP地址的思路如下:

配置主从IP地址,实现一个接口可以接入两个不同网段。

操作步骤

  1. 配置Switch的10GE1/0/1接口所属VLANIF100接口的IP地址。 
    <HUAWEI> system-view
    [~HUAWEI] sysname Switch
    [*HUAWEI] commit
    [~Switch] vlan batch 100
    [*Switch] interface 10ge 1/0/1
    [*Switch-10GE1/0/1] port default vlan 100
    [*Switch-10GE1/0/1] quit
    [*Switch] interface vlanif 100
    [*Switch-Vlanif100] ip address 172.16.1.1 24
    [*Switch-Vlanif100] ip address 172.16.2.1 24 sub
    [*Switch-Vlanif100] quit
    [*Switch] commit
    [~Switch] quit

     

  2. 验证配置结果。
