问题 交换机命令show interfaces type 0/port_#switchport|trunk用于显示中继连接的配置情况,下面是显示例子:
   2950# show interface fastEthernet 0/1 switchport
   Name:fa 0/1
   Switchport:  Enabled
   AdminiStratire mode:trunk
   Operational Mode:trunk
   AdminiStrotire Trunking Encapsulation:ctotlq
   Operational Trunking Encapsulation:dotlq
   egotiation of Trunking:Disabled
   Access Mode VLAN:0 ((Inactire))
   Trunking Native Mode VLAN:1(default)
   Trunking VLANs Enabled:ALL
   Trunklng VLANs Actlve:  1,2
   Pruning VLANs Enabled:2-1001
   Priority for untagged frames:0
   Override vlan tag priority:FALSE
   Voice VLAN:nome
   在这个例子中,端口fa 0/1的链路模式被设置为  (56)  状态,默认的VLAN是  (57)  。
(57)

选项 A、VLANO
B、VLAN1
C、VLAN2
D、VLAN3

答案B

解析 由Administrative mode:trunk和Operational Mode:trunk可看出,端口fa 0/1的链路模式被设置为trunk状态,由Trunking Native Mode VLAN:1(default)可看出,默认的VLAN是VLAN1。
