How To Configure Cisco Routers and Switches Password?

Hi, today we will look to configure Cisco routers and switches with a password. It may be seen as trivial but very important for security because a lot of issues a password related. Network devices use a lot of protocols to work and these protocols needs security. Authentication resides in security and the first rule of authentication is real check. For example, if you connect a switch with telnet you should give your credentials to gain rights to manage switch or you need to gain more rights to change switch configuration.
