2.9 Login Security
Two methods are available on the IntraCore 35516 to configure an authentication query process for better login
security: the
username
command or the
password
and
login
commands.
2.9.1 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.
Router(config)#
line console 0
Or
Router(config)#
line vty
vty-number
Router(config-line)#
login user
Router#
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).
2.9.2 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 that login user is
NOT
set by default. The “root” user is the only default user; the password is the same as line
password.
2.10 Configuring an IP Address
The switch ships with the default IP address
192.168.0.1/24
. Connect via the serial port in order to assign the switch
an IP address on your network.
The physical ports (or switchports) of the IC35516 are L2 ports, and cannot have an IP address assigned to them. By
default, each switchport belongs to VLAN 1, a virtual interface (veth1) that may be assigned a primary, as well as any
number of secondary, IP addresses. Use the following instructions to configure an IP address to the switch. The
network administrator may later assign primary IP addresses to any other VLAN created.
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.

The screen will display the user mode prompt,
