三层交换机VLAN简单配置实例

网络拓扑：

Switch1为cisco三层交换机:

增加两个vlan：

vlan database

vlan 10

vlan 20

exit

把F0/1加入vlan 10,F0/2加入vlan 20：

con t

int f0/1

swit mode acc

swit acc vlan 10

speed 100

dep full

no shut

int f0/2

swit mode acc

swit acc vlan 20

speed 100

dup full

no shut

端口F0/12作为trunk：

int f0/12

swit mode trunk

swit trunk encap dot1q

no shut

设置vlan的ip

int vlan 10

ip add 192.168.10.1 255.255.255.0

no shut

int vlan 20

ip add 192.168.20.1 255.255.255.0

no shut

exit

开启三层交换机的路由：

ip routing

exit

Switch2为支持vlan的cisco交换机：

增加vlan 10

vlan database

vlan 10

exit

把F0/1加入vlan 10

con t

int f0/1

swit mode acc

swit acc vlan 10

speed 100

dup full

no shut

端口F0/12作为trunk：

int f0/12

swit mode trunk

swit trunk encap dot1q

no shut

exit

PC1:

ip:192.168.10.11/24 gateway:192.168.10.1

PC2:

ip:192.168.20.11/24 gateway:192.168.20.1

PC3:

ip:192.168.10.12/24 gateway:192.168.10.1

测试三台PC可以互通，配置完成。
