3.4 Login Security

Two methods are available on the IntraCore IC36240 to configure an authentication query process for better login security: the username command for the global configuration mode and password and login commands from the line configuration mode.

3.4.1 The username Command

To establish a username-based authentication system, use the username command in global configuration mode. This method is more effective because authentication is determined on a user basis. The configuration is done for each line.

Switch(config)#

Switch# username name password password

The name argument can be a host name, server name, user ID, or command name. It is restricted to only one word. Blank spaces and quotation marks are not allowed.

Optionally, an encrypted password can be used, preceded by a single-digit number that defines what type of encryption is used. Currently defined encryption types are 0 (which means that the text immediately following is not encrypted) and 7 (which means that the text is encrypted using an encryption algorithm).

3.4.2 The password and login Commands

Using the password and login commands is less effective because the password is configured for the port, not for the user. Therefore, any user who knows the password can authenticate successfully.

This method enables user name and password checking at login time. Authentication is based on the user.

Note: The default login user is not set.

3.5 Configuring an IP Address

The switch ships with the default IP address 192.168.0.1/24. Connect through the serial port in order to assign the switch an IP address on your network.

Follow the steps below to change the switch’s IP address.

1.Connect to the console and press Enter at the Password prompt, as described above.

2.The screen displays the user mode prompt, Switch>.

3.Type enable. The new prompt is Switch#.

4.Type configure. The new prompt is Switch(config)#.
