Introduction
The HP 1:10Gb Ethernet BL-c Switch is ready to perform basic switching functions right out of the box.
Some of the more advanced features, however, require some administrative configuration before they can
be used effectively. This guide provides a command reference for the HP 1:10GbE switch.
The extensive switching software included in the switch provides a variety of options for accessing and
configuring the switch:
•Text-based command line interfaces (AOS CLI and ISCLI) for access via a local terminal or remote
Telnet/Secure Shell (SSH) session
•Simple Network Management Protocol (SNMP) support for access through network management
software such as HP Systems Insight Manager
•A browser-based management interface for interactive network access through a Web browser
The ISCLI provides a direct method for collecting switch information and performing switch configuration.
Use a basic terminal to view information and statistics about the switch, and to perform any necessary
configuration.
This chapter explains how to access the ISCLI to the switch.
Additional references
Additional information about installing and configuring the switch is available in the following guides,
which are available at http://www.hp.com/go/bladesystem/documentation.

•HP 1:10Gb Ethernet BL-c Switch Command Reference
•HP 1:10Gb Ethernet BL-c Switch Application Guide
•HP 1:10Gb Ethernet BL-c Switch Browser-based Interface Reference
•HP 1:10Gb Ethernet BL-c Switch Quick Setup Instructions
Connecting to the switch
You can access the command line interface in one of the following ways:
•Using a console connection via the console port
•Using a Telnet connection over the network
•Using a Secure Shell (SSH) connection to securely log in over a network

ISCLI reference
10
Establishing a console connection
To establish a console connection with the switch, you need:
•A null modem cable with a female DB-9 connector (See the HP 1:10Gb Ethernet BL-c Switch User
Guide for more information.)
•An ASCII terminal or a computer running terminal emulation software set to the parameters shown in
the table below.
Table 1 Console configuration parameters
Parameter Value
Baud Rate 9600
Data Bits 8
Parity None
Stop Bits 1
Flow Control None
To establish a console connection with the switch:
1. Connect the terminal to the console port using the null modem cable.
2. Power on the terminal.
3. Press the Enter key a few times on the terminal to establish the connection.
4. You will be required to enter a password for access to the switch.
Setting an IP address
To access the switch via a Telnet or an SSH connection, you need to have an Internet Protocol (IP) address
set for the switch. The switch can get its IP address in one of the following ways:
•Management port access:
○Using a Dynamic Host Control Protocol (DHCP) server—When the /cfg/sys/dhcp command
is enabled, the management interface (interface 256) requests its IP address from a DHCP
server. The default value for the /cfg/sys/dhcp command is enabled.
○Configuring manually—If the network does not support DHCP, you must configure the
management interface (interface 256) with an IP address. If you want to access the switch from a
remote network, you also must configure the management gateway (gateway 4).
•Uplink port access:
○Using a Bootstrap Protocol (BOOTP) server—By default, the management interface is set up to
request its IP address from a BOOTP server. If you have a BOOTP server on the network, add the
Media Access Control (MAC) address of the switch to the BOOTP configuration file located on
the BOOTP server. The MAC address can be found in the System Information (See the “System
information” section in the “Information Commands” chapter.) If you are using a DHCP server
that also does BOOTP, you do not have to configure the MAC address.
○Configuring manually—If the network does not support BOOTP, you must configure the
management port with an IP address.

ISCLI reference

Establishing a Telnet connection
A Telnet connection offers the convenience of accessing the HP 1:10GbE switch from any workstation
connected to the network. Telnet provides the same options for user, operator, and administrator access
as those available through the console port. By default, Telnet is enabled on the switch. The switch
supports four concurrent Telnet connections.
Once the IP parameters are configured, you can access the ISCLI using a Telnet connection. To establish a
Telnet connection with the switch, run the Telnet program on the workstation and enter the telnet
command, followed by the switch IP address:
telnet <HP 1:10GbE switch IP address>
You will then be prompted to enter a password. The password determines the access level: administrator,
operator, or user. See the “Accessing the switch” section later in this chapter for description of default
passwords.
Establishing an SSH connection
Although a remote network administrator can manage the configuration of a switch via Telnet, this
method does not provide a secure connection. The Secure Shell (SSH) protocol enables you to securely
log into the switch over the network.
As a secure alternative to using Telnet to manage switch configuration, SSH ensures that all data sent over
the network is encrypted and secure. In order to use SSH, you must first configure it on the switch. See the
“Secure Shell Server configuration” section in the “Configuration Commands” chapter for information on
how to configure SSH.
The switch can perform only one session of key/cipher generation at a time. Therefore, an SSH/Secure
Copy (SCP) client will not be able to log in if the switch is performing key generation at that time or if
another client has just logged in before this client. Similarly, the system will fail to perform the key
generation if an SSH/SCP client is logging in at that time.
The supported SSH encryption and authentication methods are listed below.
•Server Host Authentication—Client RSA authenticates the switch in the beginning of every connection
•Key Exchange—RSA
•Encryption:
○AES256-CBC
○AES192-CBC
○AES128-CBC
○3DES-CBC
○3DES
○ARCFOUR
•User Authentication—Local password authentication; Remote Authentication Dial-in User Service
(RADIUS)

ISCLI reference

The following SSH clients are supported:
•SSH 3.0.1 for Linux (freeware)
•SecureCRT® 4.1.8 (VanDyke Technologies, Inc.)
•OpenSSH_3.9 for Linux (FC 3)
•FedoraCore 3 for SCP commands
•PuTTY Release 0.58 (Simon Tatham) for Windows
NOTE: The HP 1:10GbE switch implementation of SSH is based on versions 1.5 and 2.0, and
supports SSH clients from version 1.0 through version 2.0. SSH clients of other versions are not
supported. You may configure the client software to use protocol SSH version 1 or version 2.
By default, SSH service is not enabled on the switch. Once the IP parameters are configured, you can
access the ISCLI to enable SSH.
To establish an SSH connection with the switch, run the SSH program on the workstation by issuing the
ssh command, followed by the user account name and the switch IP address:
>> # ssh <user>@<HP 1:10GbE switch IP address>
You will then be prompted to enter your password.
NOTE: The first time you run SSH from the workstation, a warning message might appear. At the
prompt, enter yes to continue.
Accessing the switch
To enable better switch management and user accountability, the HP 1:10GbE switch provides different
levels or classes of user access. Levels of access to the CLI and Web management functions and screens
increase as needed to perform various switch management tasks. The three levels of access are:
•User— Interaction with the switch is completely passive—nothing can be changed on the switch.
Users may display information that has no security or privacy implications, such as switch statistics
and current operational state information.
•Operator— Interaction with the switch is completely passive—nothing can be changed on the switch.
Users may display information that has no security or privacy implications, such as switch statistics
and current operational state information.
•Administrator— Administrators are the only ones that may make permanent changes to the switch
configuration—changes that are persistent across a reload/reset of the switch. Administrators can
access switch functions to configure and troubleshoot problems on the switch. Because administrators
can also make temporary (operator-level) changes as well, they must be aware of the interactions
between temporary and permanent changes.
Access to switch functions is controlled through the use of unique usernames and passwords. Once you
are connected to the switch via the local console, Telnet, or SSH, you are prompted to enter a password.
The password entered determines the access level. The default user names/password for each access
level is listed in the following table.
NOTE: It is recommended that you change default switch passwords after initial configuration and
as regularly as required under your network security policies. For more information, see the “Setting
passwords” section in the “First-time configuration” chapter.

Table 2 User access levels
User account Description and tasks performed
User The User has no direct responsibility for switch management. He or she can view all switch
status information and statistics, but cannot make any configuration changes to the switch.
The user account is enabled by default, and the default password is user.
Oper The Operator has no direct responsibility for switch management. He or she can view all switch
status information and statistics, but cannot make any configuration changes to the switch.
By default, the operator account is disabled and has no password.
Admin The super user administrator has complete access to all command modes on the switch,
including the ability to change both the user and administrator passwords.
The admin account is enabled by default, and the default password is admin.
NOTE: With the exception of the admin user, access to each user level can be disabled by setting
the password to an empty value.
Once you enter the administrator password and it is verified, you are given complete access to the
HP 1:10GbE switch.
Idle timeout
By default, the HP 1:10GbE switch disconnects the console, Telnet, or SSH session after five minutes of
inactivity. This function is controlled by the idle timeout parameter, which can be set from 1 to 60 minutes.
To change this parameter, see the “System configuration” section in the “Configuration Commands”
chapter.

ISCLI basics
Introduction
The ISCLI is used for viewing switch information and statistics. In addition, the administrator can use the
CLI for performing all levels of switch configuration.
This chapter describes the ISCLI Command Modes, and provides a list of commands and shortcuts that
typically are from all the command modes within the ISCLI.
Accessing the ISCLI
The first time you start the HP 1:10GbE switch, it boots into the AOS CLI. To access the ISCLI, enter the
following command and reset the switch:
Main# boot/mode iscli
To access the AOS CLI, enter the following command from the ISCLI and reload the switch:
Switch(config)# boot cli-mode aos
The switch retains your CLI selection, even when you reset the configuration to factory defaults. The CLI
boot mode is not part of the configuration settings.
ISCLI Command Modes
The ISCLI has three major command modes, listed in order of increasing privileges, as follows:
User EXEC mode: This is the initial mode of access. By default, password checking is disabled for this
mode.
Privileged EXEC mode: The mode is accessed from User EXEC mode. If the Privileged EXEC password is
enabled, you must enter a password to access Privileged EXEC mode.
Global Configuration mode: This mode allows you to make changes to the running configuration of the
switch. If you save the configuration, the settings survive a reload of the HP 1:10GbE switch. Several
submodes are available within the Global Configuration mode.
Each command mode provides a specific set of commands. The command set of each higher-privilege
mode is a superset of the lower-privilege mode(s). All commands available in lower-lower-privilege modes
are available in the higher-privilege modes.

Command line interface shortcuts
The following shortcuts allow you to enter commands quickly and easily.
Command abbreviation
Most commands can be abbreviated by entering the first characters that distinguish the command from
the others in the same mode. For example, consider the following full command:
Switch(config)# spanning-tree stp 1 bridge hello 2
The command shown above could also be entered as:
Switch(config)# sp stp 1 br h 2
Tab completion
Enter the first letter of a command at any prompt and press the Tab key to display all available
commands or options that begin with that letter. Entering additional letters further refines the list of
commands or options displayed.
If only one command fits the input text when you press the Tab key, that command is supplied on the
command line, waiting to be entered.
