1、设置进入特权模式的密码（加密形式）

在全局模式下输入命令 enable secret 密码 即设置完成。

jingshihai-01#jingshihai-01#config terminalEnter configuration commands, one per line.  End with CNTL/Z.jingshihai-01(config)#enable secret 111111jingshihai-01(config)#endjingshihai-01#%SYS-5-CONFIG_I: Configured from console by consolejingshihai-01#show running-config Building configuration...Current configuration : 1204 bytes!version 12.2no service timestamps log datetime msecno service timestamps debug datetime msecno service password-encryption!enable secret 5 $1$mERr$gsT/Ol5GvccluWxu2cQ1I. （加密密码）!!

2、如果同时设置了明文密码和加密密码，那么加密密码起作用

（即：加密密码的优先级大于明文密码）

3、配置console密码

在全局模式下输入命令 line console 0 回车，在输入 password 123456 回车，在输入 login 即可

jingshihai-01#config terminjingshihai-01#config terminal Enter configuration commands, one per line.  End with CNTL/Z.jingshihai-01(config)#line console 0jingshihai-01(config-line)#password 123456jingshihai-01(config-line)#loginjingshihai-01(config-line)#endjingshihai-01#show running-config Building configuration...Current configuration : 1228 bytes!version 12.2no service timestamps log datetime msecno service timestamps debug datetime msecno service password-encryption!line con 0password 999999logging synchronousloginjingshihai-01#jingshihai-01#exit

jingshihai-01 con0 is now available

Press RETURN to get started.User Access VerificationPassword: （输入console密码）jingshihai-01>enablePassword:  （输入特权模式密码）jingshihai-01#

4、配置管理用IP地址与网关

console不是唯一的管理手段，有时还需要通过网络对设备进行远程操作。

每台交换机只能配置一个管理IP地址和网关，且只能在VLAN 1中配置。

在全局模式下，输入命令 interface vlan 1 进入vlan1中；然后输入管理IP地址和网关，命令为 ip address 192.168.1.1 255.255.255.0 回车后输入 no shutdown （激活） 配置完成。

jingshihai-01#jingshihai-01#config terminalEnter configuration commands, one per line.  End with CNTL/Z.jingshihai-01(config)#interface vlan 1jingshihai-01(config-if)#ip address 192.168.1.1 255.255.255.0jingshihai-01(config-if)#no shutdownjingshihai-01(config-if)#%LINK-5-CHANGED: Interface Vlan1, changed state to upjingshihai-01(config-if)#endjingshihai-01#%SYS-5-CONFIG_I: Configured from console by consolejingshihai-01#show running-jingshihai-01#show running-config Building configuration...Current configuration : 1241 bytes!version 12.2no service timestamps log datetime msecno service timestamps debug datetime msecno service password-encryption!interface Vlan1  ip address 192.168.1.1 255.255.255.0!

通过如上可以查看输入的命令是否有问题，也可以通过如下命令查看状态：

jingshihai-01# show interface vlan 1Vlan1 is up, line protocol is down  Hardware is CPU Interface, address is 00d0.ff07.0d95 (bia 00d0.ff07.0d95)  Internet address is 192.168.1.1/24  MTU 1500 bytes, BW 100000 Kbit, DLY 1000000 usec
