Command Summary
Preparing for Configuration
To configure any Cisco Micro Hubs in a stack, the stack must include at least one
Micro Hub 1503. You can connect to the Micro Hub 1503 to configure it in one of two
ways:
•
•
Direct Connection through the CONSOLE Port
Connection Using Telnet
Direct Connection through the CONSOLE Port
You can configure the Micro Hub 1503, by connecting a terminal or a PC directly to the
hub’s CONSOLE port as described in the section “Connecting the CONSOLE Port” in the
chapter “Installing Your Hub.”
Using Your Hub Software 3-1
Preparing for Configuration
Connection Using Telnet
If the hub is correctly connected to a network, you can access the hub by using Telnet from
anywhere on that network and can use the configuration program to communicate with the
hub. Before making a Telnet connection to the hub, you must configure the hub with a valid
IP address, subnet mask, and default gateway using the configuration program.
Configuration Using a PC
If you are configuring the hub with a PC (not a dumb terminal), you need a type of
communication software called terminal emulation software to send commands to the hub.
Table 3-1
Common Terminal Emulation Software Programs

Command Conventions
Command Conventions
This section describes some things you might need to know before using the commands to
configure the hub. If you are familiar with these conventions, you can skip this section.
•
Enter commands by typing the text of the command at the configuration prompt and
then pressing the Return key.
•
There are two configuration prompt levels:
— The guest-level prompt is the device name followed by an angle bracket (>):
Hub>
— The administrator-level prompt is the device name followed by a pound sign (#). To
reach this prompt, the user (usually the system administrator) must enter a password
with the enable command:
Hub>
Hub> enable
Password: ******
Hub#
•
There are two editing modes provided by the configuration program—normal and
enhanced. For more information about the enhanced editing mode, refer to the
terminal editing command in the section “Editing Commands” later in this chapter.
The following editing commands can be used on the command line in either editing
mode:
— Backspace erases characters to the left of the cursor.
— Delete erases characters to the right of the cursor (this may be different, depending
on the terminal emulation software that you are using).
— Ctrl-C cancels a command prior to pressing the Return key.
— Tab or Ctrl-I completes a command name based on partial input.
Using Your Hub Software 3-3
Preparing for Configuration
•
You can abbreviate commands to the fewest letters that make them unique. For example,
for the show history command, you can enter:
Hub> show his
•
Certain commands display multiple screens with this prompt between screens:
--More--
Press the space bar to see more output from the command or press Return to display
the next line. Press any other key to return to the prompt.
Configuration Modes
You configure the Micro Hub 1503 (or the attached stack) with the configuration program
that is a part of the hub’s firmware. There are two configuration modes: guest mode and
administrator mode (also called privileged mode). The commands available in guest mode
are a subset of those available in administrator mode.
When you first connect to the hub, the configuration program is set to guest mode. If you
are connecting to the hub using Telnet, you must also enter a Telnet session password. To
enter administrator mode, use the enable command and enter the administrator password.
You will then be prompted to enter the enable password, as shown below:
Hub> enable
Password: <enable_password>
Setting the Administrator Password
Some commands require the user to enter a password before they can be entered. This is an
important feature because it prevents accidental or unauthorized changes to your hub
settings and to your network.
Set the password using the password command, as shown below:
Hub# password
Old Password: <old_password>
New Password: <new_password>
Hub#
3-4
Cisco Micro Hub User Guide
Forgot Your Password?
The <password> field can contain from 0 to 80 uppercase and lowercase alphanumeric
characters. Spaces are not allowed. The first character cannot be a number. Passwords are
case sensitive.
An example of a valid password is mypassword1.
Forgot Your Password?
If you forget the password that provides access to administrator-level commands or if you
forget the password required for Telnet sessions, you can bypass the password requirement
and set a new password. You must be connected to the hub through the CONSOLE port to
perform these steps.
Take the following steps:
Step 1
Turn the hub OFF, and wait 60 seconds before going to Step 2.
Step 2
Turn the hub ON, and wait while the following messages are displayed on the
terminal:
Starting the system...
Boot option : bootp get ip
Enter BOOTP phase, wait or press Ctrl-C to break...
.....
Bootup Error: Timeout, no response from BOOTP server.
Press RETURN to start a new session
Step 3
Press Ctrl-C.
Step 4
When the following prompt appears, enter a new administrator password:
New administrator password: <new_password>
Step 5
When the following prompt appears, re-enter the new password:
Confirm administrator password: <new_password>
Step 6
You are then prompted to enter and confirm a new Telnet session password, as
follows:
New telnet-session password: <new_telnet-session_password>
Confirm telnet-session password: <new_telnet-session_password>

Step 7
The following message appears, confirming that your new passwords have been
accepted:
Administrator and telnet passwords are modified.
Welcome to Cisco hub model 150x
Configuring the Hub
This section describes basic hub configuration.
Before you configure a Micro Hub 1503, have the following information available:
•
IP address and IP subnet mask that you will assign to the hub if you are accessing the
configuration program using Telnet or SNMP.
•
•
•
•
IP address for the TFTP server if you want to use TFTP bootup feature.
IP address for the BOOTP server if you want to use the BOOTP feature.
IP address of the hub’s gateway if you want to use Telnet or SNMP.
IP addresses for authorized Trap Managers, if you want management stations to receive
trap messages generated by the hub.
Note If you do not have this information, you might need to get it from your system
administrator or from your network plan before you can complete your hub configuration.
Hub ID Numbers
This section describes how to determine the hub ID number of a particular Micro Hub in a
stack of Micro Hubs. Before configuring the hub, you should understand how hubs in a
stack are identified.
You cannot manually assign a hub ID number to a hub in a stack. The hub ID number is
assigned based on how the hubs are cabled together.
Note The physical location of a hub in a stack does not determine a hub’s ID number.
3-6
Cisco Micro Hub User Guide
Hub ID Numbers
Here are two rules that determine hub ID numbers in a stack of hubs:
1 The lowest hub ID number in a stack (1) is always assigned to the hub with another hub
connected to its OUT port and with no hub connected to its IN port.
2 The highest hub ID number in a stack (any number from 2 to 5) is always assigned to
the hub with no hub connected to its OUT port and with another hub connected to its IN
port.
Figure 3-1 illustrates these rules.

Configuring the Hub
Configuring the hub takes place in three major steps:
1 Entering Administrator Mode
2 Configuring IP and SNMP Parameters
3 Configuring the SNMP Management Station
All of the commands used in the configuration steps are fully explained in the section
“Command Summary” later in this chapter.
Entering Administrator Mode
Step 1
Connect a console by following the instructions in the section “Connecting the
CONSOLE Port” in the chapter “Installing Your Hub” or start a Telnet session
with the hub.
Step 2
Turn the hub ON by setting the power switch to the ON ( | ) position.
Step 3
After a few seconds, you will see the user prompt. Use the enable command to
enter administrator mode:
Hub> enable
Step 4
After entering the command, you will be prompted to enter the administrator
password. If the administrator password has not been set, you can enter
administrator mode by pressing the Return key, as shown below:
Hub> enable
Password: <Return>
Hub#
Note If the administrator password has not been set, you should set it following
the steps in the section “Setting the Administrator Password” earlier in this
chapter. Record the password in a secure location.
The pound sign (#) after the prompt indicates that you are in administrator mode
and can enter the commands to configure the hub for IP and SNMP parameters.

Configuring the SNMP Management Station
Make sure that the SNMP management station receives traps from the Micro Hub 1503
(and any Micro Hubs connected to it in a stack) by configuring the management station as
follows:
3-10
•
•
Make sure the management station has entries for all the Micro Hubs in the stack.
•
The management station should be able to read SNMP information from the
Micro Hubs, such as port status and traffic counts.
•
The management station should be able to control and manage the Micro Hubs,
including enabling and disabling ports and changing contact information.
The entries for the Micro Hubs should have Get Community and Set Community
configured as private.
