4、vlan的规划及配置
在本节中我们讲解vlan的规划及具体的配置命令。在此例中我们用的是vtp（VLAN Trunking Protocol）server的模式，在这种模式中我们需要配置核心交换机的vtp模式为server，各接入交换机的vtp模式为cilent，那么配置完成后接入交换机就会通过trunk口自动从核心交换机学习到所有的vlan配置信息。在接入交换机中只需要添加相应的端口即可，这样易于管理与部署。具体的配置命令我们通过两小节来演示：
4.1 核心交换机的相关配置
（这是一台已经配置好了的交换机，但这并不会影响我们的演示效果。所有我们新作的配置会在演示结束后清除。）

TEST#conf t
Enter configuration commands, one per line. End with CNTL/Z.
TEST(config)#no vlan 200 # 第一步，删除vlan200
TEST(config)#no int vlan 200 # 第二步，删除int vlan200 ，经过这两步就可以彻底的删除vlan200了
TEST(config)int gi1/2 # 进入到gi1/2这个端口中
TEST(config-if)#switchport access vlan 1 # 将这个端口重新划分到vlan1中
TEST(config-if)#end
TEST#shv vlan
# 确认一下，我们成功的将gi1/2回归到vlan1中，并且删除掉了vlan200
