交换机上的MAC地址表

拓扑图：

1、首先在R1上的配置：

R1(config)#int

R1(config)#interface g

R1(config)#interface gigabitEthernet 0/0

R1(config-if)#ip add

R1(config-if)#ip address 192.168.10.1 255.255.255.0

R1(config-if)#no sh

R1(config-if)#no shutdown

R1#show int

R1#show interfaces g

R1#show interfaces gigabitEthernet 0/0

GigabitEthernet0/0 is up, line protocol is up (connected)

Hardware is CN Gigabit Ethernet, address is 0030.a303.1701 (bia 0030.a303.1701)

//show interfaces gigabitEthernet 0/0可以看到R1的g0/0接口下的MAC地址为0030.a303.1701

Internet address is 192.168.10.1/24

同理，R2上的配置跟R1相似，也可以在R2的g0/0接口下看到MAC地址

R2(config)#interface g

R2(config)#interface gigabitEthernet 0/0

R2(config-if)#ip add

R2(config-if)#ip address 192.168.10.2 255.255.255.0

R2(config-if)#no sh

R2(config-if)#no shutdown

R2#sh interfaces gigabitEthernet 0/0

GigabitEthernet0/0 is up, line protocol is up (connected)

Hardware is CN Gigabit Ethernet, address is 0001.4383.a201 (bia 0001.4383.a201)

//show interfaces gigabitEthernet 0/0可以看到R2的g0/0接口下的MAC地址为0001.4383.a201

Internet address is 192.168.10.2/24

2、SW1上的配置：

SW1(config)#int

SW1(config)#interface vlan 1

SW1(config-if)#ip add

SW1(config-if)#ip address 192.168.10.254 255.255.255.0

SW1(config-if)#no sh

SW1(config-if)#no shutdown

SW1#show mac-address-table     //查看交换机上的MAC地址表

Mac Address Table

-------------------------------------------

Vlan    Mac Address       Type        Ports

----    -----------       --------    -----

1    0001.4383.a201    DYNAMIC     Fa0/2

1    0030.a303.1701    DYNAMIC     Fa0/1
