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.
