一、VLAN聚合

1.SW1创建vlan 10 20 100

[SW1]vlan b 10 20 100

2.PC1、PC2接口设置成access，加入对应的vlan10、20

[SW1]int g0/0/1

[SW1-GigabitEthernet0/0/1]p l a

[SW1-GigabitEthernet0/0/1]int g0/0/2

[SW1-GigabitEthernet0/0/2]p l a

[SW1-GigabitEthernet0/0/2]p d vlan 20

3.将vlan100设置成Super-VLAN，vlan10、20设置成子sub vlan

[SW1]vlan 100

[SW1-vlan100]aggregate-vlan   //创建聚合VLAN超级VLAN (能够为多个子VLAN服务)

[SW1-vlan100]access-vlan  10 20

4.vlanif100设置IP使能Sub-VLAN间的Proxy ARP功能

[SW1]int vlan 100

[SW1-Vlanif100]ip add 192.168.1.254 24   //VLANIF IP作为多个子vlan的网关

[SW1-Vlanif100]arp-proxy  inter-sub-vlan-proxy  en

5.验证PC1能ping同PC2

PC1 ping PC2时，

在g0/0/1抓包，目的MAC为代理vlanif100的mac地址

在g0/0/2接口抓包观察源MAC为代理vlanif100的mac地址

二、MUX VLAN聚合

1.SW1创建vlan 10 20 30 100

[SW1]vlan b 10 20 30 100

2.所有接口设置为成access，加入相应的vlan

[SW1-GigabitEthernet0/0/1]p l a

[SW1-GigabitEthernet0/0/1]p d vlan 10

[SW1-GigabitEthernet0/0/2]p l a

[SW1-GigabitEthernet0/0/2]p d vlan 10

[SW1-GigabitEthernet0/0/3]p l a

[SW1-GigabitEthernet0/0/3]p d vlan 20

[SW1-GigabitEthernet0/0/4]p l a

[SW1-GigabitEthernet0/0/4]p a lan 20

[SW1-GigabitEthernet0/0/5] p l a

[SW1-GigabitEthernet0/0/5]p d vlan 30

[SW1-GigabitEthernet0/0/6]p l a

[SW1-GigabitEthernet0/0/6]p d vlan 30

[SW1-GigabitEthernet0/0/7]p l a

[SW1-GigabitEthernet0/0/7]p d vlan 100

3.MUX VLAN配置

[SW1]vlan 100

[SW1-vlan100]mux-vlan   //设置VLAN100为主VLAN

[SW1-vlan100]subordinate group 10 20   //设置VLAN10， 20为互通型从VLAN

[SW1-vlan100]subordinate separate 30   //设置VLAN30为隔离型从VLAN

[SW1-GigabitEthernet0/0/1]port mux-vlan  enable     //（所有接口）开启MUX VLAN功能

4.验证配置[SW1]display mux-vlanPrincipal Subordinate Type         Interface

100       -           principal    GigabitEthernet0/0/7

100       30          separate     GigabitEthernet0/0/6

100       10          group        GigabitEthernet0/0/1 GigabitEthernet0/0/2

100       20          group        GigabitEthernet0/0/3 GigabitEthernet0/0/4

PC1与PC2、服务器能互通

PC3与PC4、服务器能互通

PC5、PC6只能与服务器互通
