Hybrid 实验

Hybrid 2020-08-10

实验拓扑

实验需求

按图示给各 PC 配置 IP 地址
PC1属于 VLAN 10 ； PC2 与 PC5 属于 VLAN 20；PC4属于 VLAN 30
实现全网互通

实验步骤

1.配置链路聚合

在SW1上配置命令如下

[SW1]int Eth-Trunk 1
[SW1-Eth-Trunk1]trunkport Ethernet 0/0/1 to 0/0/3

在SW2上配置命令如下

[SW2]int Eth-Trunk 1
[SW2-Eth-Trunk1]trunkport Ethernet 0/0/1 to 0/0/3

2.验证链路聚合效果

[SW1-Eth-Trunk1]dis eth-trunk 1
Eth-Trunk1's state information is:
WorkingMode: NORMAL         Hash arithmetic: According to SIP-XOR-DIP         
Least Active-linknumber: 1  Max Bandwidth-affected-linknumber: 8              
Operate status: up          Number Of Up Port In Trunk: 3                     
--------------------------------------------------------------------------------
PortName                      Status      Weight 
Ethernet0/0/1                 Up          1      
Ethernet0/0/2                 Up          1      
Ethernet0/0/3                 Up          1

3. 在 SW1 与 SW2 上将互连的聚合接口属性设置为 Hybrid ，并允许 VLAN 10 ； VLAN 20 ； VLAN 30 通过

SW1 上配置

[SW1-Eth-Trunk1]port link-type hybrid
[SW1-Eth-Trunk1] port hybrid tagged vlan 10 20 30

SW2 上配置

[SW2-Eth-Trunk1]port link-type hybrid
[SW2-Eth-Trunk1] port hybrid tagged vlan 10 20 30

4. 在 SW1 与 SW2 上将互连 PC 的端口，赋予剥离 VLAN 10 ； VLAN 20 ； VLAN 30 标签能力，配置PVID 值和允许通过的VLAN

SW1

[SW1]int e0/0/4
[SW1-Ethernet0/0/4]port link-type hybrid 
[SW1-Ethernet0/0/4]port hybrid pvid vlan 10
[SW1-Ethernet0/0/4]port hybrid tagged vlan 10
[SW1-Ethernet0/0/4]port hybrid untagged vlan 20 30

[SW1]int e0/0/5
[SW1-Ethernet0/0/5]port link-type hybrid
[SW1-Ethernet0/0/5]port hybrid pvid vlan 20
[SW1-Ethernet0/0/5]port hybrid tagged vlan 20
[SW1-Ethernet0/0/5]port hybrid untagged vlan 10 20 30 
//因为拓扑图里PC5也属于VLAN 20；这里需要配置剥离 VLAN 20的标签，因为主机只能接收以太帧，如果接收到802.1Q的帧 则丢弃。

[SW1]int e0/0/6
[SW1-Ethernet0/0/6]port link-type hybrid 
[SW1-Ethernet0/0/6]port hybrid pvid vlan 20
[SW1-Ethernet0/0/6]port hybrid tagged vlan 20
[SW1-Ethernet0/0/6]port hybrid untagged vlan 10 20 30

SW2

[AR2]int e0/0/5
[AR2-Ethernet0/0/5]port link-type hybrid    
[AR2-Ethernet0/0/5]port hybrid pvid vlan 30 
[AR2-Ethernet0/0/5]port hybrid tagged vlan 30
[AR2-Ethernet0/0/5]port hybrid untagged vlan 10 20

5. PING 测试连通性----- PC4 Ping PC1

PC>ping 192.168.1.1

Ping 192.168.1.1: 32 data bytes,Press Ctrl_C to break
From 192.168.1.1: bytes=32 seq=1 ttl=128 time=63 ms
From 192.168.1.1: bytes=32 seq=2 ttl=128 time=78 ms

重新PING 一次，我们在 SW1 e0/0/2网段开始抓包，查看抓取的 Ping 包内容
