1. Password setting and recovery
(1) Password settings for routers and switches
① Configuring the console port password
Switch>enable
Switch> #configure Terminal
Switch (config) #line console 0
Switch (config-line) #password + password
Switch (Config-line) #logoin
② Removing the console port password
Switch (config-line) #no password
③ Configuring Privileged Mode passwords
Configure plaintext Privileged mode password Switch (config) #enable password + password
Configure redaction Privilege mode password Switch (config) #enable secret + password
Remove plaintext password Switch (config) #no enable
Delete ciphertext password Switch (config) #no enable secret
(2) Router password recovery
Press CTRL + Breack during startup to interrupt iOS loading
Enter ROM monitor mode, change the value of the configuration register from 0x2102 to 0x2142
Rommon1>confireg 0x2142
Rommon2>rest
After normal startup, cover running-config with Startup-config
Modify the password and save the value of the configuration register
Router (config) #enable secreat + new password
Router (config) #config-register 0x2102
(3) Switch password recovery
Unplug the switch, plug it in, and press and hold the mode key
"Switch:" Prompt to release key, Initialize Flash
Switch:flash_init
Change the Config.text file to Config.old and start the switch after completion
Switch:rename Flash:config.text Flash:config.old
Switch:boot
Change the name of the configuration file back
Switch:rename Flash:config.old Flash:config.text
Manually load the configuration file and then enter configuration mode to modify the password
Switch#copy Flash:config.text System:running-config
(4) Remote management of routers and switches
① Configuring IP addresses, using the ping command to test
The switch configures the IP in the Vlan1 and uses no shutdown to turn on
Switch#config Terminal
Switch (config) #interface vlan 1
Switch (config-if) #ip address + IP address + subnet mask
Switch (config-if) #no shutdown
② Configuring switch Remote functionality
Switch (config) #line vty 0 3
Switch (config-line) #password + password
Switch (Config-line) #login
③ Configuring privileged passwords with top
④ using the Telnet test in your PC
Telnet + IP Address
2. Device iOS operation
(1) iOS for routers, switches
①ios Introduction
Internetwork Operating system Internet Operating system
Features that iOS implements
Configure the address, protocol, and other parameters of the network device
Secure your network by controlling access
Set up a series of access policies
Monitoring and commissioning of equipment
(2) Setting up the Cisco router's iOS
Upgrading the Cisco router's iOS
① upgrading the Cisco router's iOS via a TFTP server
Configuring the TFTP service
Upgrade router iOS router#copy TFTP flash
Router#copy TFTP Flash
Backup router iOS router#copy flash TFTP
Router#copy flash:tftp:
② upgrading the Cisco router's iOS via an FTP server
Configuring the FTP Service
Configure the logon FTP user name, password on the router
Router (config) #ip ftp usename + login Name
Router (config) #ip ftp password + password
Upgrade your router's iOS router#copy TFTP flash
Router#copy Ftp:flash:
Backup router iOS router#copy flash FTP
Router#copy flash:ftp:
(3) iOS recovery
iOS File Recovery---an iOS file is damaged or lost
Connecting switches and hosts using the console line
# 加载IOS失败，初始化Flash Switch：flash_init -- 通过Xmodem协议传输IOS文件 Switch：copy Xmodem：flash：c2960-lanbase-mz.122-35.se5.bin -- 设置超级终端的Xmodem选项，超级终端菜单“传送” -- 启动交换机 Switch：boot
