华为交换机配置DHCP

手动配置IP

划分VLAN10、20 ，并将端口1放入VLAN10，端口2放入VLAN20。

[Huawei-GigabitEthernet0/0/2]port link-type access
[Huawei-GigabitEthernet0/0/2]port default vlan 20
[Huawei-GigabitEthernet0/0/2]

给PC1、PC2手动分配地址


最后两台PC相互ping一下看是否相通

基于端口DHCP配置

全局模式下开启DHCP
划分VLAN10、20，并将端口g0/0/1、g0/0/2分配相应VLAN
指定VLAN10、20网关
指定基于端口DHCP
指定dns
指定租期
排除分配地址范围

将PC1、PC2的DHCP开启


在命令行里查询IP以及相互相ping
pc1自动获取到192.168.10.99,pc2获取到192.168.20.99
在华为交换机里面分配地址默认从最大数开始分配（这里99，是因为配置了100-253不给分配），思科交换机默认是是从最小数开始分配。

基于全局DHCP配置

全局开启DHCP
创建VLAN10、20
VLAN分配IP并指定DHCP模式
端口分入相应VLAN
创建地址池10、20
指定各自的网关、dns、租期、不给分配地址

pc1、2开启自动获取，相互ping
pc1分配到192.168.10.253地址
pc2分配到192.168.20.200（配置排除了分配20.201-20.253地址）
