Access+Trunk 配置

实验拓扑

实验需求

1. 按图示给各 PC 配置 IP 地址
2. 在SW1和SW2上创建聚合组
3. PC1 与 PC3 属于 VLAN 10 ； PC2 与 PC4 属于 VLAN 20
4. 利用 Access 与 Trunk 端口属性，解决同 VLAN 的 PC 能够互通，不同 VLAN 的 PC 无法互通

实验步骤

1. 在SW1创建聚合组，设置为Trunk类型

[SW1]int Eth-Trunk 12
[SW1-Eth-Trunk12]trunkport Ethernet 0/0/1 to 0/0/3
[SW1-Eth-Trunk12]port trunk allow-pass vlan all

2. 在SW2创建聚合组，设置为Trunk类型

[SW2]int Eth-Trunk 12
[SW2-Eth-Trunk12]trunkport Ethernet 0/0/1 to 0/0/3
[SW2-Eth-Trunk12]port trunk allow-pass vlan all

3. 在SW2上查看聚合组

[SW2-Eth-Trunk12]dis eth-trunk 12
Eth-Trunk12'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

4. SW1 上划分VLAN 10 设置为Access 端口

 [SW1]vlan batch 10 20
 [SW1]int e0/0/4
 [SW1-Ethernet0/0/4]port link-type access
 [SW1-Ethernet0/0/4]port default vlan 10

[SW1]int e0/0/5
[SW1-Ethernet0/0/5]port link-type access
 [SW1-Ethernet0/5]port default vlan 20

5. SW2 上划分VLAN 20 30 ，设置为Access端口

[SW2]VLAN 20
[SW2]int e0/0/4
[SW2-Ethernet0/0/4]port link-type access
[SW2-Ethernet0/0/4]port default vlan 20

6. PC2 PING PC3 在相同VLAN 可以互通
