D.spanning-tree vlan 30 root primary
第1题:
A、access vlan vlan-id
B、port link-type trunk
C、port trunk allow-pass vlan
D、set port vlan vlan-id
答:B、C
解析:
(1) 首先我们需要确定我们需要用到的端口模式:
Access介入模式 pc—交换机 Trunk中继链路模式: 交换机—交换机
(2) 其次在两个交换机上各创建vlan5、vlan10的端口,并把pc19与pc21的端口设置为access模式并加入vlan5,把pc20与pc22的端口设置为access模式并加入vlan10,把两个交换机相连接的端口设置为trunk中继链路模式,并把vlan端口加入到中继链路。
(3) 最后,打开计算机,使用ping命令进行查看。

[Huawei]vlan batch 5 10 //创建vlan端口
[Huawei]interface ethernet 0/0/1 //进入e0/0/1端口进行配置
[Huawei-Ethernet0/0/1]port link-type access //设置端口的模式为access
[Huawei-Ethernet0/0/1]port default vlan 5 //把端口加入vlan 5
[Huawei-Ethernet0/0/1]interface ethernet 0/0/2 //进入e0/0/2端口进行配置
[Huawei-Ethernet0/0/2]port link-type access //设置端口模式为access
[Huawei-Ethernet0/0/2]port default vlan 10 //把端口加入vlan 5
[Huawei-Ethernet0/0/2]interface ethernet 0/0/3 //进入e0/0/3端口
[Huawei-Ethernet0/0/3]port link-type trunk //设置端口模式为trunk
[Huawei-Ethernet0/0/3]port trunk allow-pass vlan 5 10 //把vlan 5 10加入到中继链路
