思科路由器的基本设置（主机名，密码）

我们这里主要通过思科的命令行界面CLI对路由器进行基本配置，路由器为Cisco1841，在进入CLI之前，要用串口线将电脑和路由器的Console接口相连，打开电脑主机的超级终端，进行如下设置

点击确定，然后显示如下信息

--- System Configuration Dialog ---

Continue with configuration dialog? [yes/no]:
我们输入NO，然后回车，再回车，将出现router>
将路由器的主机名修改成R1
Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname R1
R1(config)#

设置访问特权模式的访问密码,第一种是设置特权密码
R1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#enable password 123456
R1(config)#
另一种是设置特权加密密码
R1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#enable secret 3636
R1(config)#

特权密码和特权加密密码的区别在于前者未被加密，通过show running-config命令即可以明文的方式显示出来，而特权加密密码则被以加密的方式显示出来，即乱码。
R1>enable
Password:
R1#show running-config
Building configuration...

enable secret 5 $1$mERr$Nyhjc1apmhq3YBhha65.8.
enable password 123456

再有就是配置控制台端口（console口）和虚拟终端口（通过网络访问）的密码
R1(config)#line console 0 *配置控制台端口*
R1(config-line)#password 2525
R1(config-line)#login
R1(config-line)#exit
R1(config)#line vty 0 4 *虚拟终端口*
R1(config-line)#password 1414
R1(config-line)#login
R1(config-line)#exit
R1(config)#

以上是思科路由器的几个基本设置命令，其他命令待续
