  创建VLAN的步骤
  1.定义VTP
  
  COS
  
  set vtp domain domain-name
  
  
  IOS
  
  (vlan) vtp domain domain-name
  
  或者
  
  (global) vtp domain domain-name
  
  
  2.创建VLAN
  
  COS
  
  set vlan vlan-id [name name] [state state] [mtu mtu]
  
  
  IOS
  
  (vlan) vlan vlan-id [name vlan-name] [state {suspend active}] [mtu mtu-size]
  
  
  (global) vlan vlan-id
  
  
  (vlan-config) vlan vlan-id [mtu mtu-size] [name vlan-name] [state {suspend active}]
  
  
  举例
  
  CatOS
  
  (enable)>set vtp mode transparent
  
  (enable)>set vlan 5 name Cameron
  
  (enable)>set vlan 8 name Logan
  
  (enable)>set vlan 10 name Katie
  
  (enable)>set spantree macredUCtion enable
  
  (enable)>set vlan 2112 name Rush
  
  (enable)>
  
  
  IOS
  
  #vlan database
  
  (vlan)#vtp transparent
  
  (vlan)#vlan 5 name Cameron
  
  (vlan)#vlan 8 name Logan
  
  (vlan)#vlan 10 name Katie
  
  (vlan)#exit
  
  #copy running-config startup-config
  
  
  TRUNK
  
  An example of the Catalyst OS configuration for Distribution_1 follows:
  
  
  Distribution_1 (enable)>clear trunk 1/1 2-1001
  
  Distribution_1 (enable)>set trunk 1/1 desirable isl 10
  
  Distribution_1 (enable)>clear trunk 2/1 2-1001
  
  Distribution_1 (enable)>set trunk 2/1 on dot1q 5,8,10
  
  An example of the Catalyst OS configuration for Core_1 follows:
  
  
  Core_1 (enable)>clear trunk 1/1 2-1001
  
  Core_1 (enable)>set trunk 1/1 10
  
  An example of the Supervisor IOS configuration for Core_1 follows:
  
  
  Core_1(config)#interface gigabitethernet 1/1
  
  Core_1(config-if)#switchport encapsulation negotiate
  
  Core_1(config-if)#switchport mode dynamic auto
  
  Core_1(config-if)#switchport trunk allowed vlan remove 2-1001
  
  Core_1(config-if)#switchport trunk allowed vlan add 10
  
  Core_1 (config-if)#end
  
  Core_1#copy running-config startup-config
  
  An example of the Layer 2 IOS configuration for access_1 follows:
  
  
  Access_1 (config)#interface gigabitethernet 0/1
  
  Access_1 (config-if)#switchport mode trunk
  
  Access_1 (config-if)#switchport trunk encapsulation dot1q
  
  Access_1 (config-if)#switchport trunk allowed vlan remove 2-1001
  
  Access_1 (config-if)#switchport trunk allowed vlan add 5,8,10
  
  Access_1 (config-if)#end
  
  Access_1#copy running-config startup-config
  
  
  An example of the Catalyst OS configuration for Core_1 follows:
  
  
  Core_1 (enable)>set vtp mode transparent
  
  Core_1 (enable)>set trunk 1/1 on isl
  
  Core_1 (enable)>set trunk 1/2 on isl
  
  Core_1 (enable)>
  
  An example of the Catalyst OS configuration for Distribution_1 follows:
  
  
  Distribution_1 (enable)>set vtp domain GO-CATS
  
  Distribution_1 (enable)>set trunk 1/1 on isl
  
  Distribution_1 (enable)>set trunk 2/1 on dot1Q
  
  Distribution_1 (enable)>set vtp PRuning enable
  
  Distribution_1 (enable)>clear vtp pruneeligible 10
  
  An example of the Catalyst OS configuration for Distribution_2 follows:
  
  
  Distribution_2 (enable)>set trunk 1/1 on isl
  
  Distribution_2 (enable)>clear vtp pruneeligible 10
  
  An example of the Layer 2 IOS configuration for Access_1 follows:
  
  
  Access_1#vlan database
  
  Access_1 (vlan)#vtp client
  
  Access_1 (vlan)#exit
  
  Access_1 #config t
  
  Access_1 (config)#interface gigabitethernet 0/1
  
  Access_1 (config-if)#switchport mode trunk
  
  Access_1 (config-if)#switchport trunk encapsulation dot1Q
  
  Access_1 (config-if)#switchport trunk pruning vlan remove 10
  
  Access_1 (config-if)#end
  
  Access_1#copy running-config startup-config
