Cisco IOS : How to configure passwords.
August 22, 2013 2 Comments
Cisco switches and routers 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.
