Would you like to enter the initial configuration dialog? [yes/no]: n 输入n（自己手工一点点的设置）

Press RETURN to get started!

Switch> 首先看到的是用户模式

Switch>en 输入en（即enable）进入特权模式

1y13w: %LINK-5-CHANGED: Interface Vlan1, changed state to administratively down

1y13w: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to down

Switch#conf t 进入配置模式

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)#hostname xy_c2950t24_e0201 给交换机命名

xy_c2950t24_e0201(config)#enable password Cisco 给交换机配置管理口令（明码的）

xy_c2950t24_e0201(config)#line vty 0 4 给交换机开启远程管理

xy_c2950t24_e020(config-line)#pass Cisco! 设置远程管理口令

xy_c2950t24_e020(config-line)#login 允许远程登陆

xy_c2950t24_e020(config-line)#exit 退出到上级目录

xy_c2950t24_e0201(config)#int vlan 1 进入vlan1 接口

xy_c2950t24_e0201(config-if)#no shut 开启此接口

1y13w: %LINK-3-UPDOWN: Interface Vlan1, changed state to up

1y13w: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to up

xy_c2950t24_e0201(config-if)#ip add 172.25.161.22 255.255.255.0 设置此接口地址

xy_c2950t24_e0201(config-if)#exit 退出到上一层

xy_c2950t24_e0201(config)#ip default-gateway 172.25.161.16 将交换机的网关指向上联交换机

xy_c2950t24_e0201(config)#int ran gi 0/1 - 2 配置上连下连端口

xy_c2950t24_(config-if-range)#sw mo tr 将此端口设置成trunk

xy_c2950t24_(config-if-range)#no shut 开启此端口

xy_c2950t24_(config-if-range)#exit 退出到上一级目录

xy_c2950t24_e0201(config)#int ran fa 0/1 - 24 进入一段接口range一段范围,接电脑用户

xy_c2950t24_(config-if-range)#no shut 开启此段端口

xy_c2950t24_(config-if-range)#sw mo acc 将此段端口设置成问接入access模式

xy_c2950t24_(config-if-range)#exit 退出到上一级目录

（公司内部没有设置VLAN，所以没有用到将此段端口划分到某个vlan里的命令：sw acc vlan 2 ）

xy_c2950t24_e0201(config)#vtp mo cl 设置vtp(vlan transport portocol)模式为client（一般来讲，汇聚和接入交换机都配置成client）

Setting device to VTP CLIENT mode.

xy_c2950t24_e0201(config)#vtp domain xyass 设置vtp域名（只有域名相同的情况下，vlan信息才能透传过来）

Domain name already set to xyass.

xy_c2950t24_e0201(config)#end 退到根目录

xy_c2950t24_e0201#wr 保存配置

4d00h: %SYS-5-CONFIG_I: Configured from console by console

Building configuration...

[OK] （保存好了，已经生效）

以上就是全部设置过程。

几个常用的查看命令：
show running-config 查看当前配置

show vtp status 查看当前vtp状态

show cdp nei 查看当前邻居属性
show vlan 查看vlan 信息

删除配置信息的命令，用于不需要旧的配置，希望全部清空信息，重新配置

write erase 删除所有配置信息（小心！）
