Hybrid的一种特殊特性

深入理解hybrid的工作原理

工作原理：一般交换机划分vlan后，必须用第三层的设备才能相互通讯，但由于华为的交换机端口有hybrid壮态，所以可用第二层设备使vlan间相互通讯，通过这个实验可以充分理解trunk与hybrid的不同

工作过程：交换机sw1与sw2的E0/0/0采用hybrid相连，sw1及sw4交换机工作在vlan10,sw2及sw3交换机工作在vlan20，通过设置使vlan 10与vlan 20间通讯

工作图：

 

 

工作过程：

一.交换机sw1的配置

[sw1]vlan 10

[sw1-vlan10]port e0/0/4

[sw1-vlan10]q

[sw1]int e0/0/0

[sw1-Ethernet0/0/0]port link-type hybrid

[sw1-Ethernet0/0/0]port hybrid pvid vlan 10

[sw1-Ethernet0/0/0]port hybrid vlan 10 untagged

 Please wait... Done.

二.交换机sw2的配置

[sw2]vlan 20

[sw2-vlan20]port e0/0/4

[sw2-vlan20]q

[sw2]int e0/0/0

[sw2-Ethernet0/0/0]port link-type hybrid

[sw2-Ethernet0/0/0]port hybrid pvid vlan 20

[sw2-Ethernet0/0/0]port hybrid vlan 20 untagged

三.vlan10这边下层交换机的配置

[sw3]vlan 10

[sw3-vlan10]port e0/0/4

[sw3-vlan10]q

[sw3]int vlan

[sw3]int Vlan-interface 10

[sw3-Vlan-interface10]ip add 192.168.11.10 24

[sw3-Vlan-interface10]sh  

[sw3-Vlan-interface10]un sh

四.vlan20这边下层交换机的配置

[sw4]vlan 20

[sw4-vlan20]port e0/0/4

[sw4-vlan20]int vlan 20

[sw4-Vlan-interface20]ip add 192.168.11.20 24

[sw4-Vlan-interface20]sh

[sw4-Vlan-interface20]un sh
