4.2 接入交换机的相关配置
## 在此例中，我们联入的是一台接入交换机，此交换机的gi0/1口上联至核心交换机。也就意味着我们需要配置gi0/1为trunk口。具体的配置如下：
D-2960-3(config)#int gi0/1
D-2960-3(config-if)#sw
D-2960-3(config-if)#switchport mo
D-2960-3(config-if)#switchport mode ?
access Set trunking mode to ACCESS unconditionally
dynamic Set trunking mode to dynamically negotiate access or trunk mode
trunk Set trunking mode to TRUNK unconditionally
D-2960-3(config-if)#switchport mode trunk
## 配置此接口的模式为trunk，在cisoc2960交换机中，配置完接口模式为trunk后就可以了，不需要进一步配置此trunk口的封装状态，因为其默认的也是唯一的封装类型就是dot1q，并且此系列交换机并没有专门的封装配置命令。
D-2960-3(config-if)#exit
D-2960-3(config)#exit
D-2960-3#sh int tru # 退至特权配置模式验证一下刚才的配置
Port Mode Encapsulation Status Native vlan
Gi0/1 auto 802.1q trunking 1
# 这个端口已经配置成trunk模式，并且封装成802.1q了
Port Vlans allowed on trunk
Gi0/1 1-4094
Port Vlans allowed and active in management domain
Gi0/1 1-2,10,20,30,40,50,60,70,80,100,110,120,150,160
Port Vlans in spanning tree forwarding state and not pruned
Gi0/1 1-2,10,20,30,40,50,60,70,80,100,110,120,150,160
D-2960-3#conf t # 进入到全局配置模式
D-2960-3(config)#vtp mode client
# 配置vtp模式为client，与核心交换机的server模式相呼应。
D-2960-3(config)#vtp domain pjoe
# 配置vtp域为pjoe，只有一个域中的交换机才能互传vlan信息。
D-2960-3(config)#vtp password pjoeserver # 配置vtp密码
D-2960-3(config)#end
D-2960-3#sh vtp status # 退出到特权模式验证一下刚才的有关vtp的配置
VTP Version : 2
Configuration Revision : 23
Maximum VLANs supported locally : 255
Number of existing VLANs : 19
VTP Operating Mode : Client # 模式已经设置成client
VTP Domain Name : pjoe # 域名已经设置成pjoe
VTP Pruning Mode : Disabled

##稍等一会后，验证一下是否学习到了核心交换机的vlan信息，它的学习有一小段的过程30秒的样子。
D-2960-3#sh vlan # 验证一下vlan信息是否全部学到。
