Cisco交换机入门配置的方法
你还在为不知道Cisco交换机入门配置的方法而烦恼么?接下来是小编为大家收集的Cisco交换机入门配置的方法教程,希望能帮到大家。
Cisco交换机入门配置的方法:
机型:Cisco 3750
想对交换机警醒配置。一般有两种方法:
1、控制台端口(Console):可以直接对交换机进行配置
2、远程登录(Telnet):通过TELNET程序对已经设置了IP的交换机进行远程配置,一般等控制台端口配置好交换机的IP后才可以进行。
除了以上的两种方法外,其实还有两种方法:
1、WEB的配置方式。此方法只能配置一般的简单设置
2、硬件自带的应用程序。专用的程序,一般很少用
建立控制台连接到交换机
一般交换机自带一根Console线,一端连接到交换机的Comsole口,一端连接到电脑的串行口。打开超级终端,一般就可以连接到交换机。具体的参数设置如下
这样就可以连接到交换机了
连接到交换机后,如果是第一次启动会要执行初始化操作,一般是设置交换机的名称,密码等一般的信息。
由于交换机已经初始化,如果要进行初始化操作,那就要进入特权EXEC模式,在命令提示符号下输入:setup,就会启动初始化操作。
刚才讲到了特权EXEC模式,这理就要讲一下觉换机的几种模式,不同的模式可以执行不同的操作命令,首先来说两种基本的模式。
一般为了安全考虑,CISCO将操作会话分为两个不同的访问级别:用户EXEC级别和特权EXEC级别。用户EXEC级别只能使用有限的命令,且交换机显示Switch>提示符,不能对交换机进行配置。看例子,处于用户EXEC级别下的状态:
AITG_FrontekCoreSW>
特权EXEC级别下交换机显示Switch#提示符,能对交换机进行各种配置。看例子,处于特权EXEC级别下的状态:
输入en,进入特权EXEC级别,接着输入密码,进入特权EXEC级别
AITG_FrontekCoreSW>en
Password:
AITG_FrontekCoreSW#
看看,提示符变了,用户在用户EXEC级别输入enable(或en),然后输入密码,就可以进入特权EXEC级别
在交换机提示符下输入“?”,可以列出相应模式下交换机所支持的所有命令。
退出特权EXEC级别模式:disable
再用户EXEC级别输入?可以获得帮助信息:
AITG_FrontekCoreSW>?

其实还有几种模式如下:
全局配置模式:Switch(config)# 配置交换机的全局参数
接口配置模式:Switch(config-if)# 对交换机的接口进行配置,如某个接口属于那个Vlan,启用及禁用 接口等
线路配置模式:Switch(config-line)# 对控制台访问
VLAN数据库配置模式:Switch(Vlan)# 对Vlan的参数进行配置
