基于MAC划分vlan

组网需求

实现MAC与vlan绑定，防止私接设备访问：

CE1下联PC2,3配置Hybird接口
配置untag vlan 100，禁止vlan 1
接口开启mac-vlan
绑定mac与vlan

组网拓扑

配置文件

bash 复制代码

!
mac-vlan mac-address 0050.7966.6802 vlan 100 priority 0
mac-vlan mac-address 0050.7966.6803 vlan 100 priority 0
!
interface GigabitEthernet 0/1
 switchport mode hybrid
 switchport hybrid allowed vlan only tagged 2-99,101-4094
 switchport hybrid allowed vlan add untagged 100
 mac-vlan enable
!
interface GigabitEthernet 0/2
 switchport mode hybrid
 switchport hybrid allowed vlan only tagged 2-99,101-4094
 switchport hybrid allowed vlan add untagged 100
