Good evening friends, Today we will see how to configure passwords on Cisco routers and switches. Cisco devices have four types of passwords.
- Console password : Used to set password for the console access.
- Auxiliary password : It is used to set password to auxiliary port ( if the switch has one.)
- VTY lines password : Used to set password for for telnet and SSH access.
- Privileged password : Used to set password for privileged access to the switch.
I am not going to show you how to set up auxiliary password here. To see how to set up console password and VTY lines password, go here.
Privileged mode of a Cisco device has some advanced IOS commands that can have disastrous consequences if used by wrong hands. So it is very important to set up a password to access privileged commands. Use the following commands
The “enable” command takes us into privileged mode. The “conf t” mode takes us into global configuration mode which pertains to the configuration settings of the whole switch. The “enable password” sets a password for the privileged mode. ‘123456’ is the password. The “exit” command takes us out of the privileged mode. To see if a password has been set for the privileged mode, try entering into privileged mode by typing “en” command. We can see that it prompts us for the password.
