路由与交换技术期末速成（Cisco）

登录与管理交换机

为交换机命名为sw1，配置进入特权模式的密码

Switch>en

Switch#conf t

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

Switch(config)#hostname sw1

sw1(config)#en secret 123456

sw1(config)#enable secret 123456

 配置远程登录的密码

sw1(config)#line vty 0 4//进入线路配置模式，同时配置0-4个虚拟终端用户

sw1(config-line)#password 000000

sw1(config-line)#login//开启登录认证功能

sw1(config-line)#exit

 配置交换机远程管理的ip地址

sw1#conf t

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

sw1(config)#int vlan 1

sw1(config-if)#ip addr 192.168.100.3 255.255.255.248

sw1(config-if)#end

查看vlan虚接口的状态

 sw1#show int vlan 1

Vlan1 is administratively down, line protocol is down

 开启vlan虚接口

sw1#conf t

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

sw1(config)#int vlan 1

sw1(config-if)#no shut

sw1(config-if)#

%LINK-5-CHANGED: Interface Vlan1, changed state to up

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

sw1(config-if)#end

 再次检查vlan虚接口状态

sw1#

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

show int vlan
