路由交换学习第二天：初识MAC地址表

Posted 2022-05-26

AS1内的设备全启动：

PC配置：
打开PC1的配置，设置静态IP：10.10.10.1 255.255.255.0=》应用
（备注：PC1的mac：54-89-98-B1-7B-52）

路由器设置：

<Huawei>system-view //进入系统视图
[Huawei]sys HW-R1 //设置路由器名称
[HW-R1]interface GigabitEthernet 0/0/1 //配置GE0/0/1口
[HW-R1-GigabitEthernet0/0/1]ip address 10.10.10.11 24 //设置IP信息
[HW-R1-GigabitEthernet0/0/1]dis th //查看GE0/0/1当前配置
[V200R003C00]

HW-SW3的mac add信息:

[HW-SW3]display mac-address //查看MAC ADD信息
MAC address table of slot 0:

MAC Address VLAN/ PEVLAN CEVLAN Port Type LSP/LSR-ID
VSI/SI MAC-Tunnel

5489-98b1-7b52 1 - - GE0/0/10 dynamic 0/- `` //在GE0/0/10口下以动态方式得到MAC，在VLAN1
00e0-fc39-67ab 1 - - GE0/0/1 dynamic 0/-

Total matching items on slot 0 displayed = 2

HW-SW1的mac add信息:

[HW-SW1]display mac-address
MAC address table of slot 0:

MAC Address VLAN/ PEVLAN CEVLAN Port Type LSP/LSR-ID
VSI/SI MAC-Tunnel

5489-98b1-7b52 1 - - GE0/0/5 dynamic 0/- //在GE0/0/5口下以动态方式得到MAC，在VLAN1
00e0-fc39-67ab 1 - - GE0/0/1 dynamic 0/-

Total matching items on slot 0 displayed = 2

HW-SW2的mac add信息:

[HW-SW2]display mac-address
MAC address table of slot 0:

MAC Address VLAN/ PEVLAN CEVLAN Port Type LSP/LSR-ID
VSI/SI MAC-Tunnel

00e0-fc39-67ab 1 - - GE0/0/5 dynamic 0/-
5489-98b1-7b52 1 - - GE0/0/1 dynamic 0/- //在GE0/0/1口下以动态方式得到MAC，在VLAN1

Total matching items on slot 0 displayed = 2

[HW-SW2]display mac-address aging-time //查看mac地址老化时间
Aging time: 300 seconds //300秒

注：如果某个MAC超过300没有发送数据，MAC地址会在交换机地址表中删除。老化时间可以修改，mac发送数据后交换机也可以重新学习到MAC。
