We use Passwords to Protect our Networking Devices
To Configure the Passwords in Cisco Switch/Router
Ø Switch/Router(Config) # enable password Cisco
(This
password in shown on Clear text in our Running Configuration So we did not use
this password we use Enable Password)
Ø Switch/Router (Config) # enable secret Cisco
(This
is level 5 encryption This type of
password is very Difficult to Crack and this is not shown in Clear text
Instead of Hashing (MD5) form)
To Remove:-
Ø Switch/Router #no enable password
3rd Console port password to Protect our Console Port because
someone plug the console cable in our switch and destroy our network)
To console port:-
Ø Switch/Router (Config)# Line console 0
Ø Switch/Router (config-line)#Password Cisco
Ø Switch/Router(config-line) #login (when we
plug the Cable It will ask the Password)
Ø Switch/Router(config-line) #exit
4th Type of Password is telnet Passwords
(We
use telnet to Remotely Access our Networking Devices)
To Telnet:-
Ø Switch/Router (Config)# line vty 0 4 (5 Usear simultaneously access the device)
Ø Switch/Router(config-line) #Password Cisco
Ø Switch/Router(config-line) #login (When we use
telnet it will prompt us For Password)
Ø Switch/Router(config-line) #exit
Ø Auxiliary only for Router (used to connect with modem)
(Switch have no Auxiliary Port)
Ø Auxiliary only for Router (used to connect with modem)
(Switch have no Auxiliary Port)
Ø Router (Config)# line aux 0
Ø Router(config-line)#Password Cisco
Ø Router(config-line) #login (When we use telnet it will prompt us For Password)
Ø Router(config-line) #exit
Because our Console and telnet Password in
Clear Text
To encrypt The all Password
Ø Switch/Router (Config)#service password-encryption
(This is level 7 encryption Every
single password encrypt on Cisco devices But this type of password encryption
is easily Breakable )
Ø To Break Level 7 encryption
