vlan实验
1.PC1和pC3所在接口为access;属于 vlan2;
pc2/4/5/6处于同一网段;其中pc2可以访问pc4/5/6;但p4可以访问pc5，不能访问pc6
2.PC5不能访问pc6
3.PC1/3与PC2/4/5/6不在同一个网段
4.所有pc通过DHCP获取IP地址，且pC1/3可以正常访问pc2/4/5/6
配置vlan
[sw1]vlan batch 2 to 5
[sw1-GigabitEthernet0/0/1]port link-type t-----定义sw1链接路由器的接口为trunk
[sw1-GigabitEthernet0/0/1]port trunk allow-pass vlan 2 3----允许携带2和3的标签的数据传送
[sw1-GigabitEthernet0/0/1]int g 0/0/2
[sw1-GigabitEthernet0/0/2]port link-type hybrid
[sw1-GigabitEthernet0/0/2]port hybrid pvid vlan 3--- 接口PVID为3
[sw1-GigabitEthernet0/0/2]port hybrid tagged vlan 2
[sw1-GigabitEthernet0/0/2]port hybrid untagged vlan 1 3
[sw1-GigabitEthernet0/0/3]port link-type access
[sw1-GigabitEthernet0/0/3]port default vlan 2
[sw1-GigabitEthernet0/0/4]port link-type access
[sw1-GigabitEthernet0/0/4]port default vlan 2
[sw2-GigabitEthernet0/0/1]port link-type hybrid
[sw2-GigabitEthernet0/0/1]port hybrid pvid vlan 1
[sw2-GigabitEthernet0/0/1]port hybrid tagged vlan 2
[sw2-GigabitEthernet0/0/1]port hybrid untagged vlan 1 4 5
[sw2-GigabitEthernet0/0/2]port link-type trunk
[sw2-GigabitEthernet0/0/2]port trunk allow-pass vlan 4 5
[sw2-GigabitEthernet0/0/3]port link-type access
[sw2-GigabitEthernet0/0/3]port default vlan 2
[sw2-GigabitEthernet0/0/4]port link-type hybrid
[sw2-GigabitEthernet0/0/4]port hybrid pvid vlan 4
[sw2-GigabitEthernet0/0/4]port hybrid untagged vlan 1 4
[sw2-GigabitEthernet0/0/4][sw3-GigabitEthernet0/0/1]port link-type trunk
[sw3-GigabitEthernet0/0/1]port trunk allow-pass vlan 4 5
[sw3-GigabitEthernet0/0/2]port link-type hybrid
[sw3-GigabitEthernet0/0/2]port hybrid pvid vlan 4
[sw3-GigabitEthernet0/0/2]port hybrid untagged vlan 1 4
[sw3-GigabitEthernet0/0/3]port link-type hybrid
[sw3-GigabitEthernet0/0/3]port hybrid pvid vlan 5
[sw3-GigabitEthernet0/0/3]port hybrid untagged vlan 1 5配置R1,并开启DHCP
[r1-GigabitEthernet0/0/0]int g 0/0/0.1
[r1-GigabitEthernet0/0/0.1]ip add 12.1.1.1 24
[r1-GigabitEthernet0/0/0.1]dot1q termination vid 2
[r1-GigabitEthernet0/0/0.1]arp broadcast enable
[r1-GigabitEthernet0/0/0.1]int g 0/0/0.2
[r1-GigabitEthernet0/0/0.2]ip add 13.1.1.1 24
[r1-GigabitEthernet0/0/0.2]dot1q termination vid 3
[r1-GigabitEthernet0/0/0.2]arp broadcast enable
启动DHCP服务并配置
[r1]dhcp enable
[r1]ip pool one
[r1-ip-pool-one]network 12.1.1.0 mask 24
[r1-ip-pool-one]gateway-list 12.1.1.1
[r1-ip-pool-one]dns-list 114.114.114.114
[r1]ip pool two
[r1-ip-pool-two]network 13.1.1.0 mask 24
[r1-ip-pool-two]gateway-list 13.1.1.1
[r1-ip-pool-two]dns-list 8.8.8.8
接口调用
[r1-GigabitEthernet0/0/0.1]dhcp select global
