# 子网划分
|
|
|
|
|
|
|
|
### 一、VLAN
|
|
|
|
- **SW2**
|
|
|
|
```
|
|
[SW2]vlan batch 10 20
|
|
[SW2]int g0/0/2
|
|
[SW2-GigabitEthernet0/0/2]port link-type access
|
|
[SW2-GigabitEthernet0/0/2]port default vlan 10
|
|
[SW2-GigabitEthernet0/0/2]int g0/0/3
|
|
[SW2-GigabitEthernet0/0/3]port link-type access
|
|
[SW2-GigabitEthernet0/0/3]port default vlan 20
|
|
[SW2-GigabitEthernet0/0/3]int g0/0/1
|
|
[SW2-GigabitEthernet0/0/1]port link-type trunk
|
|
[SW2-GigabitEthernet0/0/1]port trunk allow-pass vlan all
|
|
```
|
|
|
|
- **SW3**
|
|
|
|
```
|
|
[SW3]vlan batch 30 40
|
|
[SW3]int g0/0/2
|
|
[SW3-GigabitEthernet0/0/2]port link-type access
|
|
[SW3-GigabitEthernet0/0/2]port default vlan 30
|
|
[SW3-GigabitEthernet0/0/2]int g0/0/3
|
|
[SW3-GigabitEthernet0/0/3]port link-type access
|
|
[SW3-GigabitEthernet0/0/3]port default vlan 40
|
|
[SW3-GigabitEthernet0/0/3]int g0/0/1
|
|
[SW3-GigabitEthernet0/0/1]port link-type trunk
|
|
[SW3-GigabitEthernet0/0/1]port trunk allow-pass vlan all
|
|
```
|
|
|
|
### 二、DHCP
|
|
|
|
- **SW1**
|
|
|
|
```
|
|
[SW1]dhcp enable
|
|
[SW1]ip pool vlan10
|
|
[SW1-ip-pool-vlan10]network 192.168.100.0 mask 26

|
|

|
|
[SW1-ip-pool-vlan40]dns-list 223.5.5.5 223.6.6.6
|
|
[SW1-ip-pool-vlan40]quit
|
|
[SW1]port-group group-member g0/0/1 g0/0/2
|
|
[SW1-port-group]port link-type trunk
|
|
[SW1-port-group]port trunk allow-pass vlan all
|
|
[SW1-port-group]quit
|
|
[SW1]vlan batch 10 20 30 40
|
|
[SW1]int vlan 10
|
|
[SW1-Vlanif10]ip add 192.168.100.62 26
|
|
[SW1-Vlanif10]dhcp select global
|
|
[SW1-Vlanif10]int vlan 20
|
|
[SW1-Vlanif20]ip add 192.168.100.126 26
|
|
[SW1-Vlanif20]dhcp select global
|
|
