1.交换机SWA的Ethernets端口配置如下:
1.交换机SWA的Ethernets端口配置如下:
interface Ethernet 1/0/1
port link-type trunk
port trunk permit vlan 10
port trunk pvid vlan 20
现在要把交换机SWA的Ethernet1/0/1端口修改为Hybrid端口,PVID为VLAN20,且在发送VLAN20的数据帧是不打标签,在发送VLAN 10的数据帧时打标签,则下面的配置过程正确的是 ( )。(A和B的区别)
A
[SWA-Ethernet1/0/1]port link-type access
[SWA-Ethernet1/0/1]port access vlan 20
[SWA-Ethernet1/0/1]port link-type hybrid
[SWA-Ethernet1/0/1]port hybrid vlan 10 tagged
B
[SWA-Ethernet1/0/1]portlink-type access
[SWA-Ethernet1/0/1]port link-type hybrid
[SWA-Ethernet1/0/1]port hybrid pvid vlan 20
[SWA-Ethernet1/0/1]port hybrid vlan 10 tagged
C
[SWA-Ethernet1/0/1]undo portlink-type
[SWA-Ethernet1 /0/1 ]portlink-type hybrid
[SWA-Ethernet1/0/1]port hybrid pvid vlan 20
[SWA-Ethernet1/0/1]port hybrid vlan 10 tagged
D
[SWA-Ethernet1/0/1]port link-type hybrid
答案解析
正确答案：A
解析：
题目解析：正确的配置过程是将交换机SWA的Ethernet1/0/1端口修改为Hybrid端口, PVID为VLAN20，发送VLAN20的数据帧不打标签，发送VLAN 10的数据帧时打标签。选项A中的配置过程符合要求，先将端口修改为access模式并指定VLAN 20为PVID，然后将端口修改为Hybrid模式并指定VLAN 10为tagged。因此，答案为A。
