交换机端口自动获取地址或手动修改地址
为了解决在某些情况下交换机端口需要支持自动获取地址和手动修改地址。
技术原理：IP子网VLAN+端口VLAN
配置示例：
这里以H3C交换机的Ethernet 1/0/1口为例：
[H3C]vlan 10
[H3C-vlan10]ip-subnet-vlan 1 ip 172.16.10.0 255.255.255.0
[H3C-vlan10]ip-subnet-vlan 2 ip 172.16.20.0 255.255.255.0
[H3C-vlan10]quit
[H3C]interface Vlan-interface 10
[H3C-Vlan-interface10]ip address 172.16.10.254 24
[H3C-Vlan-interface10]ip address 172.16.20.254 24 sub
[H3C-Vlan-interface10]quit
[H3C]vlan 100
[H3C-vlan100]quit
[H3C]interface Vlan-interface 100
[H3C-Vlan-interface100]ip address 172.16.100.254 24
[H3C-Vlan-interface100]dhcp select server #地址池自己配置
[H3C-Vlan-interface100]quit
[H3C]dhcp enable
[H3C]interface Ethernet 1/0/1
[H3C-Ethernet1/0/1]port link-type hybrid
[H3C-Ethernet1/0/1]port hybrid ip-subnet-vlan vlan 10 #启用IP子网VLAN，支持手动修改地址
[H3C-Ethernet1/0/1]port hybrid pvid vlan 100 #启用端口VLAN，支持DHCP获取地址
[H3C-Ethernet1/0/1]port hybrid vlan 10 100 untagged
[H3C-Ethernet1/0/1]display this
#
interface Ethernet1/0/1
port link-type hybrid
port hybrid vlan 1 10 100 untagged
port hybrid pvid vlan 100
port hybrid ip-subnet-vlan vlan 10
#
return
