配置vlan，将0/0/1接口与0/0/2接口进行链路聚合操作 
[sw1]vlan batch 2 3 20 30
[sw1]int Eth-Trunk 0
[sw1-Eth-Trunk0]trunkport GigabitEthernet 0/0/1 to 0/0/2    
[sw1-Eth-Trunk0]port link-type trunk 
[sw1-Eth-Trunk0]port trunk allow-pass vlan 2 3 20 30
[sw1-Eth-Trunk0]q
[sw1]int g0/0/3

[sw2-GigabitEthernet0/0/4]port link-type trunk
[sw2-GigabitEthernet0/0/4]port trunk allow-pass vlan 2 3 20 30

在sw3、sw4上创建vlan2、3、20、30并将对应接口分配到对应vlan中
[sw3]vlan batch 2 3 20 30
[sw3]int g0/0/1
[sw3-GigabitEthernet0/0/1]port link-type access 
[sw3-GigabitEthernet0/0/1]port default  vlan 2

sw3开启端口保护
[sw3-GigabitEthernet0/0/1]stp ed    
[sw3-GigabitEthernet0/0/1]stp edged-port e    
[sw3-GigabitEthernet0/0/1]stp edged-port enable 

使用Vlanif接口，sw1中对vlan2的相关配置如下
[sw1]interface Vlanif 2
[sw1-Vlanif2]ip address 10.0.2.1 24
[sw1-Vlanif2]vrrp vrid 1 virtual-ip 10.0.2.254

[sw2-Vlanif30]vrrp vrid 1 preempt-mode timer delay 20    
[sw2-Vlanif30]vrrp vrid 1 track interface GigabitEthernet 0/0/5 reduced 30

让交换机从网段中下发IP地址
[sw1]dhcp enable 
[sw1]ip pool vlan2    
[sw1-ip-pool-vlan2]network 10.0.2.0 mask 24
 
[sw1-ip-pool-vlan2]gateway-list 10.0.2.254    
[sw1-ip-pool-vlan2]dns-list 8.8.8.8
 
[sw1-ip-pool-vlan2]excluded-ip-address 10.0.2.1 10.0.2.128
 
[sw1]interface Vlanif 2
[sw1-Vlanif2]dhcp select global 
 
[sw1]interface Vlanif 3
[sw1-Vlanif3]dhcp select global 
    
[sw1]interface Vlanif 20
[sw1-Vlanif20]dhcp select global 
 
[sw1]interface Vlanif 30
[sw1-Vlanif30]dhcp select global
