Cisco Routers Basic & Advanced Commands
Basic Management Modes of Cisco Router
User Exec Mode
Router >
Privilege Mode
Router #
Global Configuration Mode
Router (config) #
Difference among Basic Management Mode
1. All the configuration and modification will be done on globle configruation mode.
2 .From privilege mode, we can perform following task:
(a). we can see contents of RAM, NVRAM & IOS.
(b). we can copy RAM, NVRAM & IOS.
(c). we can reboot the router softly.
3. From user exec mode, we can see only limited information.
How to change Host name ?
Router > enable
Router # configure terminal
Router (config) # hostname RA
RA(config) # hostname NCP
NCP(config) #
How to set enable password?
NCP(config) # enable password noida
NCP(config) # exit
NCP # exit
Now router display Messages Console 0 is now available Press Enter
NCP >
NCP >enable
Password: (Enter password noida)
After type the password noida you will get privilege mode.
NCP #
If we run show running-config command on privilege mode then password will be displayed.
NCP # show running-config
(The old method was to use the enable password command. But this is not secure (weak encryption) and is ABSOLUTELY NOT RECOMMENDED. DO NOT USE!)
How to set enable Secret Password ?
NCP(config)# enable secret ccna
NCP(config)# exit
NCP#logout
NCP > enable
Password: (Enter password ccna)
Here enable password noida will not be accepted, enable secret password ccna will be accepted due to High priority over enable password & also not visible in
#show running-config.
How to set console Password ?
NCP(config)# line console 0
NCP(config-line)# password 1234
NCP(config-line)# login
NOTE:- If we do not write login consol password will not activate.
How to set Telnet Password ?
NCP(config)# line vty 0 4
NCP(config-line)# password 789
Note :- Telnet password is use to access REMOTE DEVICES & it must be configured on REMOTE DEVICES.
How to set exec time of router window?
NCP (config)# line console 0
NCP (config)# exec-timeout 0 0
How to set Banner ?
NCP (config)# banner motd @ WELCOME TO NCP @
Note:- It will display before login into Router
How to stop broadcast of wrong command ?

How to avoid the splitting of the command line?
NCP(config)# line console 0
NCP(config- line)# logging synchronous
How to configure IP Address on Router interfaces?
Before configure IP address on interfaces we must know current status of router interfaces via #show ip interface brief Command on privilege mode .
NCP# show ip interface brief
NOTE:- By default all the port of router are Administratively down.
We can configured IP on Cisco router interfaces in following ways:-
MANUAL
NVRAM
TFTP
DHCP
How to configure IP Address on Ethernet port ?
NCP(config)# interface ethernet 0
NCP(config-if)# ip address 192.168.1.254 255.255.255.0
NCP(config-if)# no shutdown
NCP(config-if)#
