思科交换机配置vlan

如果要配置二台6509之间的Trunk联接,首先将二6509用千兆光纤相联好,然后分别配置二相联端口的trunk,可以是只用一双光纤,或用二对光纤做port channel,配置如下:

思科交换机配置vlan

  一双光纤相联时,分别在二台65上进行以下的配置:

interface GigabitEthernet1/1

no ip address

switchport

switchport trunk encapsulation dot1q

switchport trunk native vlan 1

二对光纤相联时,必须要做port channel,分别在二台65上进行以下的配置:

interface port-channe1

no ip address

switchport

switchport trunk encapsulation dot1q

switchport trunk native vlan 1

!

interface GigabitEthernet1/1

no ip address

duplex full

speed 1000

switchport mode trunk

switchport trunk encapsulation dot1q

switchport trunk native vlan 1

channel-group 1 mode on

!

interface GigabitEthernet1/2

no ip address

duplex full

speed 1000

switchport mode trunk

switchport trunk encapsulation dot1q

switchport trunk native vlan 1

channel-group 1 mode on

  VTP裁剪

(1)在基于IOS的交换机上配置VTP 模式:

switch# vlan database

switch(vlan)# vtp domain domain-name

switch(vlan)# vtp {sever|cilent|transparent}

switch(vlan)# vtp password password

在基于CLI的.交换机上配置VTP 模式:

switch(enable) set vtp [domain domain-name] [mode{ sever|cilent|transparent }][password password]

(2)在基于IOS的交换机上配置VTP版本:

switch# vlan database

switch(vlan)# vtp v2-mode

在基于CLI的交换机上配置VTP版本:

switch(enable) set vtp v2 enable

(3)在基于IOS的交换机上启动VTP剪裁:

switch# vlan database

switch(vlan)# vtp pruning

在基于CLI 的交换机上启动VTP剪裁:

switch(enable) set vtp pruning enable
