Cisco device console port Authentication

The console port is a port for each network management device. By default, authentication is not performed and plug-and-play is enabled. To ensure security, we can authenticate the console port, there are two authentication methods: 1. password 2. user name + Password

Take Cisco configuration as an example:

1. Password

Line console 0: Enter the console Port

Password cisco configure the password to cisco

Login commands must be typed. If you do not enter the login Command, the login command is not authenticated.

2. User Name + Password

Username cisco password cisco creates a user name and password on the local device

Line console 0: Enter the console Port

Call the local user name and password for login local login verification

The above two methods make the user name more secure.
