Configuring passwords on Cisco routers and switches

In this affiliate, we will meet how to configure passwords on Cisco routers and switches. Cisco devices have four types of passwords.

Console password : Used to prepare password for the console access.
Auxiliary password : It is used to set up password to auxiliary port ( if the switch has one.)
VTY lines password : Used to set password for telnet and ssh access.
Privileged countersign : Used to set password for privileged access to the switch
I am non going to prove you how to fix auxiliary password here. Privileged mode of a Cisco device has some avant-garde IOS commands that can have disastrous consequences if used by incorrect hands. So it is very important to prepare a password to access privileged commands.Employ the post-obit commands.

The "enable" control takes us into privileged mode. The "conf t" mode takes united states into global configuration fashion which pertains to the configuration settings of the whole switch. The "enable countersign" sets a password for the privileged fashion. '123456' is the password. The "exit" command takes us out of the privileged way. To come across if a password has been gear up for the privileged mode, attempt inbound into privileged style past typing "en" command.

Encrypting passwords on Cisco routers and switches.

In the previous chapter, we have seen how to set passwords on Cisco switches or routers. Of course setting passwords does add to the security of the device but at that place is a minor problem. The countersign is stored in plain text. Anyone who gets access to the switch can hands run into all the passwords by typing command "show running-config or show startup-config". Today we volition see how to encrypt passwords on Cisco routers and switches.

Encrypting passwords can farther enhance the security of the device. Privileged countersign tin be encrypted by using the command "enable secret" instead of "enable countersign". This control should exist prepare from privileged global configuration style.

Let's run across what can we see when we use the command "testify running-config".

We can encounter that the password we prepare has been encrypted, only what about other passwords. The console, auxiliary and vty lines passwords cannot exist encrypted even if we apply "enable hole-and-corner" control. To encrypt those passwords, we take to use another command "service password-encryption" as shown below.
