4.2 接入交換機的相關配置
## 在此例中,我們聯入的是一台接入交換機,此交換機的gi0/1口上聯至核心交換機。也就意味着我們需要配置gi0/1為trunk口。具體的配置如下:
D-2960-3(config)#int gi0/1
D-2960-3(config-if)#switchport mode trunk
## 配置此接口的模式為trunk,在cisoc2960交換機中,配置完接口模式為trunk后就可以了,不需要進一步配置此trunk口的封裝狀態,因為其默認的也是唯一的封裝類型就是dot1q,並且此系列交換機並沒有專門的封裝配置命令。
D-2960-3(config-if)#exit
D-2960-3(config)#exit
D-2960-3#sh int tru # 退至特權配置模式驗證一下剛才的配置
Port Mode Encapsulation Status Native vlan
Gi0/1 auto 802.1q trunking 1
# 這個端口已經配置成trunk模式,並且封裝成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 # 進入到全局配置模式
D-2960-3(config)#vtp mode client
# 配置vtp模式為client,與核心交換機的server模式相呼應。
D-2960-3(config)#vtp domain pjoe
# 配置vtp域為pjoe,只有一個域中的交換機才能互傳vlan信息。
D-2960-3(config)#vtp password pjoeserver # 配置vtp密碼
D-2960-3(config)#end
D-2960-3#sh vtp status # 退出到特權模式驗證一下剛才的有關vtp的配置

##稍等一會后,驗證一下是否學習到了核心交換機的vlan信息,它的學習有一小段的過程30秒的樣子。
D-2960-3#sh vlan # 驗證一下vlan信息是否全部學到。
