实验拓扑图：
实验配置思路：
1、查看动态MAC地址表项
2、配置静态MAC地址表项
3、配置黑洞MAC地址表项
静态表项和黑洞表项都优于动态表项
静态表项和黑洞表项重启后不会消失，动态表项重启之后会消失
实验摘要重点命令：
<Huawei>dis mac-address //查看MAC地址表
[Huawei]mac-address aging-time 305 //修改MAC地址老化时间
[Huawei]mac-address static 5489-985C-681A GigabitEthernet 0/0/2 vlan 1 //配置静态MAC地址表
[Huawei]mac-address blackhole 5489-98B7-5543 vlan 1 //配置黑洞MAC地址表项
实验详细配置步骤：
PC1——ping PC1
PC4 ping PC1使交换机生成MAC地址表

SW1——查看动态MAC地址表项
形成的是动态表项，默认老化时间为300S
<Huawei>dis mac-address //查看MAC地址表
MAC address table of slot 0:
-------------------------------------------------------------------------------
MAC Address VLAN/ PEVLAN CEVLAN Port Type LSP/LSR-ID VSI/SI MAC-Tunnel
-------------------------------------------------------------------------------
5489-9801-7cf2 1 - - GE0/0/1 dynamic 0/- //动态MAC地址表项
5489-987c-3773 1 - - GE0/0/4 dynamic 0/- //动态MAC地址表项

Total matching items on slot 0 displayed = 2 <Huawei>
SW1——修改MAC地址老化时间
[Huawei]mac-address aging-time 305 //修改MAC地址老化时间
SW1——配置静态MAC地址表项
由用户手动配置，并下发到各接口板，表项不会老化
[Huawei]mac-address static 5489-985C-681A GigabitEthernet 0/0/2 vlan 1 //配置静态MAC地址表项
SW1——查看MAC地址表
查看静态配置的MAC地址表项
[Huawei]dis mac-address //查看MAC地址表
MAC address table of slot 0:
-------------------------------------------------------------------------------
MAC Address VLAN/ PEVLAN CEVLAN Port Type LSP/LSR-ID VSI/SI MAC-Tunnel
-------------------------------------------------------------------------------
5489-985c-681a 1 - - GE0/0/2 static - //静态MAC地址表项
-------------------------------------------------------------------------------
Total matching items on slot 0 displayed = 1 [Huawei]
SW1——配置黑洞MAC地址表项
由用户手动配置，并下发到各接口板，表项不可老化
配置黑洞MAC地址后，源MAC地址或目的MAC是该MAC的报文将会被丢弃
[Huawei]mac-address blackhole 5489-98B7-5543 vlan 1 //配置黑洞MAC地址表项
SW1——查看MAC地址表
查看黑洞MAC地址表项
[Huawei]dis mac-address //查看MAC地址表
MAC address table of slot 0:
-------------------------------------------------------------------------------

-------------------------------------------------------------------------------
Total matching items on slot 0 displayed = 2 [Huawei]
PC4——ping PC1
由于配置PC3的黑洞MAC地址
源MAC地址或目的MAC是该MAC的报文将会被丢弃
