2.6.1 10/100/1000BaseT Ports Cabling Procedures
The 10/100/1000 ports on the switch allow for the connection of 10BaseT, 100BaseTX, or 1000BaseT network
devices. The ports are compatible with IEEE 802.3 and 802.3u standards.
15 Asante IntraCore IC36240 User’s Manual
Important: The switch must be located within 100 meters of its attached 10BaseT or 100BaseTX devices.
Use the following guidelines to determine the cabling requirements for the network devices:
• Connecting to Network Station: Category 5 UTP (Unshielded Twisted-Pair) straight-through cable (100 m
maximum) with RJ-45 connectors
• Connecting to Repeater/Hub/Switch’s Uplink port: Category 5, UTP straight-through cable (100 m maximum)
with RJ-45 connectors
Note: These switches have no specific uplink ports. All 10/100/1000 ports on these switches are auto-sensing
MDI/MDI-X. This advanced feature means that when the ports are operating at 10/100Mbps, they will automatically
determine whether the device at the other end of the link is a hub, switch, or workstation, and adjust its signals
accordingly. No crossover cables are required.
Although 10/100BaseT requires only pins 1, 2, 3, and 6, you should use cables with all eight wires connected as
shown in Table 2-2 below.
1000BaseT requires that all four pairs (8 wires) be connected correctly, using Category 5 or better Unshielded
Twisted Pair (UTP) cable (to a distance of 100 meters). Table 2-2 shows the correct pairing of all eight wires.

emulation program, such as HyperTerminal or by using telnet.
3.1 Connecting to a Console
To connect the switch to a console or computer, set up the system in the following manner:
1. Plug power cord into the back of the switch.
2. Attach a straight-through serial cable between the RS232 console port and a COM port on the PC.
3. Set up a HyperTerminal (or equivalent terminal program) in the following manner:
a. Open the HyperTerminal program, and from its file menu, right-click on Properties.
b. Under the Connect To tab, choose the appropriate COM port (such as COM1 or COM2).
c
d
b
c. Under the Settings tab, choose Select Terminal keys for Function, Arrow, and Ctrl keys. Be sure the setting
is for Terminal keys, NOT Windows keys
d. Choose VT100 for Emulation mode.

Now that terminal is set up correctly, power on the switch. The boot sequence will display in the terminal.
After connecting to the console, the following appears:
User Access Verification
Password:
The initial default password for access using either the console or telnet is Asante (case-sensitive). Refer to the
following section for setting passwords on the terminal lines.
3.2 Connecting to a PC
You can connect to the switch through a PC by using either an Ethernet or USB cable. Using a telnet session, you
can telnet into the switch. The default IP address is 192.168.1.1. The case-sensitive default password is Asante.
19 Asante IntraCore IC36240 User’s Manual
3.3 Passwords and Privileges Commands
The switch has not default password, which allows anyone on the network access to various privilege levels. To
prevent unauthorized changes to the switch’s configuration, you should set an enable password for access to switch
management. Follow the example below to assign a privileged password.
Switch> enable
Password: <no password by default; press Enter>
Switch# configure
Switch(config)# enable password ?
0 Specifies an UNENCRYPTED password will follow
7 Specifies a HIDDEN password will follow
LINE The UNENCRYPTED (cleartext) 'enable' password
Switch(config)# enable password 0 <password>
Switch(config)# exit
Switch# write [memory file]
A separate password should be set for the primary terminal line (console) and the virtual terminal lines (telnet). The
default password Asante is assigned only to the virtual terminal line Vty0. Up to three other virtual terminal lines may
be created, and they each will require a separate password.
3.3.1 Privileges Commands
The following sections describe the password privileges commands used to control access to different levels of the
switch:
• Enable Password
• Password
• Service Password-Encryption
3.3.2 Enable Password
To set a local password to control access to various privilege levels, use the enable password command in global
configuration mode. Use the no form of this command to remove the password requirement.
Switch(config)# enable password ?
0 Specifies an UNENCRYPTED password will follow
7 Specifies a HIDDEN password will follow
LINE The UNENCRYPTED (cleartext) 'enable' password
Switch(config)# enable password 0 <password>
Switch(config)# exit
Switch# write [memory file]
20 Asante IntraCore IC36240 User’s Manual
3.3.3 Password
To specify a password on a line, use the password command in line configuration mode. Use the no form of this
command to remove the password.
Switch(config)# line ?
console Primary terminal line
vty Virtual terminal
Switch(config)# line console ?
<0-0> Line number
Switch(config)# line console 0
Switch(config-line)# ?
end End current mode and change to enable mode

3.3.4 Service Password-Encryption
To encrypt passwords, use the service password-encryption command in global configuration mode. Use the no
form of this command to restore the default. Refer to section 4.7 “Using the No Form and Default Commands” for
more information.
Switch(config)# service password-encryption
Switch(config)# no service password-encryption
Note: You should change the default telnet password to prevent unauthorized access to the switch.
The password can be set at unencrypted (level 0) or encrypted (level 7).
Switch(config-line)# password ?
LINE The UNENCRYPTED (cleartext) line password
0 Specifies an UNENCRYPTED line password will follow
7 Specifies a HIDDEN line password will follow
21 Asante IntraCore IC36240 User’s Manual
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)#.
22 Asante IntraCore IC36240 User’s Manual
5. Type ip address and the new address. The following screen appears:
Switch> enable
Switch# configure
Switch(config)# ip address 192.168.123.254/24
Switch(config)# end
Switch# show ip
Dhcp Client Enabled ..........: No
IP Address ...................: 192.108.250.51
Subnet Mask ..................: 255.255.255.0
Default Gateway ..............: 192.108.250.5
HTTP Server ..................: Enabled
HTTP Port ....................: 80
Switch# write file
Writing current-config to startup-config. Please wait.
Configuration saved to startup-config file
It is also acceptable to enter the subnet mask by typing ip address 192.168.123.254/24. Use the show
interface veth1 command from privileged mode to see the new IP address. The new IP address automatically writes
over the default IP address.
See Chapter 6 for more information on assigning IP addresses to interfaces.
3.5.1 Setting a Default IP Gateway Address
To define the default IP gateway for the switch, insert a static route:
Switch(config)# ip default-gateway 192.168.0.254
3.6 Restoring Factory Defaults
To restore the switch to its factory default settings, follow the commands shown in the following screen.
Switch> enable
Switch# reload ?
fac-dflt-except-IP Reset ALL system parameters except IP parameters to factory
default
factory-default Reset ALL system parameters to factory default
<cr>
The switch is ready for configuration. Refer to the following chapters for management and configuration information.
3.7 System Boot Parameters
The IntraCore IC36240 has two boot banks to store its runtime code. You can select which bank to use for the next
boot with the following command:
Switch(config)# boot system flash {bank1|bank2}
23 Asante IntraCore IC36240 User’s Manual
Chapter 4: Understanding the Command Line Interface (CLI)
The switch utilizes Command Line Interface (CLI) to provide access to several different command modes. Each
command mode provides a group of related commands.
After logging into the system, you are automatically in the user top (user EXEC) mode. From the user top mode you
can enter into the privileged top (privileged EXEC) mode. From the privileged EXEC level, you can access the global
configuration mode and specific configuration modes: interface, Switch, and route-map configuration. Entering a
question mark (?) at the system prompt allows you to obtain a list of commands available for each command mode.
Almost every Switch configuration command also has a no form. You can use the no form to disable a feature or
function. For example, ARP is enabled by default. Specify the command no arp to disable the ARP table.
Document Conventions
Command descriptions use the following conventions:
• Vertical bars ( | ) separate alternative, mutually exclusive, elements
• Square brackets ([ ]) indicate optional elements
• Braces ({ }) indicate a required choice
• Braces within square brackets ([{ }]) indicate a required choice within an optional element
• Boldface indicates commands and keywords that are entered literally as shown
• Italics indicate arguments for which you supply values
Access Each Command Mode
The following sections describe how to access each of the CLI command modes:
• User Top Mode: Switch>
• Privileged Top Mode: Switch#
• Global Configuration Mode: Switch(config)#
• Interface Configuration Mode: Switch(config-if-IFNAME)#
4.1 User Top (User EXEC) Mode
After you log in to the Switch, you are automatically in user top (user EXEC) command mode. The user-level prompt
consists of the host name followed by the angle bracket (>):
Switch>
The default host name is Switch unless it has been changed during initial configuration, using the setup command.
The user top commands available at the user level are a subset of those available at the privileged level. In general,
the user top commands allow you to connect to remote devices, change terminal settings on a temporary basis,
24 Asante IntraCore IC36240 User’s Manual
To list the commands available in user top mode, enter a question mark (?). Use a space and a question mark (?)
after entering a command to see all the options for that particular command.

(with no space between the letter and the question mark). See section 3.8.2.
Lists the user EXEC commands.
Lists all the options available for the given command.
4.2 Privileged Top (Privileged EXEC) Mode
Because many of the privileged commands set the system configuration parameters, privileged access can be
password protected to prevent unauthorized use. The privileged command set includes those commands contained
in user EXEC mode, as well as the configure command through which you can access the remaining command
modes. Privileged EXEC mode also includes high-level testing commands, such as debug.
The following example shows how to access privileged EXEC mode. Notice the prompt changes from Switch> to
Switch#:
Switch> enable
Switch#
Command Purpose
Switch> enable
Switch# ?
If you have set a password, the system prompts for it before allowing access to privileged EXEC mode. If an enable
password has not been set, the enable mode can be accessed only through the console. You can enter the enable
password global configuration command to set the password that restricts access to privileged mode.
To return to user EXEC mode, use the disable command.
Enters the privileged EXEC mode.
Lists privileged EXEC commands.
25 Asante IntraCore IC36240 User’s Manual
In general, the top (privileged) commands allow you to change terminal settings on a temporary basis, perform basic
tests, and list system information. To list the commands available in top mode, enter a question mark (?) at the
prompt, as shown in the following example. Enter a question mark (?) after a command to see all the options for that
command.
Switch> enable
Switch# ?

show Show running system information
snmp-server SNMP related functions
write Write running configuration to memory, network, or terminal
cls Clear screen
Important: To retain configuration changes after a system reload you must save changes made in running
configuration to the startup configuration file. From the privileged level, configurations can be saved using the write
command or by using the copy running-config startup-config command.
4.3 Global Configuration Mode
Global configuration commands apply to features that affect the system as a whole, rather than just one protocol or
interface. Commands to enable a particular routing function are also global configuration commands. To enter the
global configuration mode, use the configure command.
The following example shows how to access and exit global configuration mode and list global configuration
commands.
Command Purpose
Switch# configure
Switch(config)# ?
From privileged EXEC mode, enters global configuration mode.
Lists the global configuration commands.

27 Asante IntraCore IC36240 User’s Manual
4.3.1 Interface Configuration Mode
Many features are enabled on a per-interface basis. Interface configuration commands modify the operation of an
interface such as an Ethernet or serial port. Interface configuration commands always follow an interface global
configuration command, which defines the interface type as Ethernet.
In the following example shows configuration of Ethernet interface (eth1). The new prompt, Switch(config-if-
eth1)#, indicates the interface configuration mode. In this example, the user asks for help by requesting a list of
commands.

configuration mode and return to top mode, use the end command or press Ctrl-Z.
4.4 Advanced Features Supported within the Command Mode
Enter a question mark (?) at the system prompt to display a list of commands available for each command mode. You
can also get a list of any command's associated keywords and arguments with the context-sensitive help feature.
29 Asante IntraCore IC36240 User’s Manual
To get help specific to a command mode, a command, a keyword, or an argument, perform one of the following
commands:
Command Purpose
Help
?
Obtain a brief description of the help system in any command mode.
List all commands available for a particular command mode.
When using context-sensitive help, the space (or lack of a space) before the question mark (?) is significant. To
obtain a list of commands that begin with a particular character sequence, type in those characters followed
immediately by the question mark (?). Do not include a space. This form of help is word help, because it completes a
word for you.
To list keywords or arguments, enter a question mark (?) in place of a keyword or argument. Include a space before
the question mark (?). This form of help is command syntax help, because it reminds you which keywords or
arguments are applicable based on the command, keywords, and arguments you already have entered.
You can abbreviate commands and keywords to the number of characters that allow a unique abbreviation. For
example, you can abbreviate the configure command to config. Because the shortened form of the command is
unique, the switch accepts the shorted form and executes the command.
Enter the help command (which is available in any command mode) for a brief description of the help system:
Switch# help
CLI/VTY provides advanced help feature. When you need help,
anytime at the command line please press '?'.
If nothing matches, the help list will be empty and you must backup until entering a
'?' shows the available options.
Two styles of help are provided:
1. Full help is available when you are ready to enter a command argument (e.g. 'show
?') and describes each possible argument.
2. Partial help is provided when an abbreviated argument is entered and you want to
know what arguments match the input (e.g. 'show cl?'.)
Switch# show cl?
clock Display the system clock
Switch# show cl
As described in the help command output, you can enter a partial command name and a question mark (?) to obtain
a list of commands beginning with a particular character set.
Example of Context Sensitive Help
The following example illustrates how the context-sensitive help feature creates an access list from the configuration
mode.
Enter the letters “co” at the system prompt followed by a question mark (?). Do not leave a space between the last
letter and the question mark (?). The system provides the commands that begin with co.
Switch# co?
configure Enter configuration mode
copy Copy from one file to another
Switch# co
Enter the configure command followed by a space and a question mark (?) to list the command’s keyword(s) and a
brief explanation:
