1.1 VLAN
vlan batch xxx
interface g0/0/x
port link-type access
port default vlan xxx
1.2 Trunk
port link-type trunk
port trunk allow-pass vlan all
注意事项:
考试LAB使用真机，在交换机上改端口模式时候需要先把端口下的默认配置删除，5700和3700删除命令不一样
SW1/SW2为5700，互联端口下敲入undo port hybrid untag vlan 1
SW3/SW4为3700，互联端口下敲入port hybrid untag vlan 1
1.3 GVRP
gvrp #全局配置
gvrp #trunk接口配置
port trunk pvid 255 #如果不允许VLAN1通过trunk
1.4 MSTP
interface g0/0/2 #根防护在接口下，bpdu防护在全局下
stp root-protection

flush send control-vlan 12
interface 13 #SW1与SW2上互联trunk口，不关闭stp只配置接收vlan12
smart-link flush receive control-vlan 12
interface 19 #SW1和SW2上与SW4互联接口，关闭stp并配置接收vlan12
stp disable
smart-link flush receive control-vlan 12
