VLAN学习总结

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] [sta

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
