CHAPTER 1
The Command Line Interface
Your GbE Switch Module (GbESM) 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.
The extensive Alteon OS switching software included in your switch provides a variety of
options for accessing and configuring the switch:
A built-in, text-based command line interface and menu system for access via a Telnet ses-
sion or serial-port connection
SNMP support for access through network management software such as IBM Director or
HP OpenView
Alteon OS Browser-Based Interface (BBI)
The command line interface is the most direct method for collecting switch information and
performing switch configuration. Using a basic terminal, you are presented with a hierarchy of
menus that enable you to view information and statistics about the switch, and to perform any
necessary configuration.
This chapter explains how to access the Command Line Interface (CLI) for the switch.
40M2420, April 2007 19
Alteon OS Command Reference
Connecting to the Switch
You can access the command line interface in any one of the following ways:
Using a Telnet via the management module
Usin g a Telnet connection over the network
Using a SSH connection to securely log into another computer over a network
Usin g a serial co nnection using the serial port on the GbESM
Management Module Setup
The BladeCenter GbE Switch Module is an integral subsystem within the overall BladeCenter
system. The BladeCenter chassis includes a management module (MM) as the central element
for overall chassis management and control.
You can use the 100 Mbps Ethernet port on the management module to configure and manage
the GbE Switch Module. The GbE Switch Module communicates with the management module through its internal port 15 (MG T1) and port 16 (MGT2), which you can access through the
Ethernet port on the management module. The factory default settings will permit only management and control access to the switch module through the Ethernet port on the management
module, or the built-in serial port. You can use the six external 10/100/1000 Mbps Ethernet
ports on the switch module for management and control of the switch by selecting this mode as
an option through the management module configuration utility program (see the appli cable
BladeCenter Installation and User ’s Guide publications for more information).
Factory-Default vs. MM assigned IP Addresses
Each GbE Switch Module must be assigned its own Internet Protocol address, which is used
for communication with an SNMP network manager or other transmission control protocol /
Internet Protocol (TCP/IP) applications (for example, BootP or TFTP). The factory-default IP
address is 10.90.90.9x, where x corresponds to the number of the bay into which the GbE
Chapter 1: The Command Line Interface 40M2420, April 2007
20
Alteon OS Command Reference
Switch Module is installed. For additional information, see the Installation Guide). The management module assigns an IP address of 192.168.70.1xx, where xx corresponds to the number
of the bay into which each GbE Switch Module is installed, as shown in the following table:
Table 1-1 GbESM IP addresses, based on switch-module bay numbers
Bay number Factory-default IP address IP address assigned by MM
Bay 1 10.90.90.91 192.168.70.127
Bay 2 10.90.90.92 192.168.70.128
Bay 3 10.90.90.94 192.168.70.129
Bay 4 10.90.90.97 192.168.70.130
NOTE – Switch Modules installed in Bay 1 and Bay 2 connect to server NICs 1 and 2, respectively. However , Windows operating systems show that Switch Modules installed in Bay 3 and
Bay 4 connect to server NICs 4 and 3, respectively.
Default Gateway
The default Gateway IP address determines where packets with a destination address outside
the current subnet should be sent. Usually, the default Gateway is a router or host acting as an
IP gateway to handle connections to other subnets of other TCP/IP networks. If you want to
access the GbE Switch Module from outside your local network, use the management module
to assign a default Gateway address to the GbE Switch Module. Choose I/O Module Tasks >
Configuration from the navigation pane on the left, and enter the default Gateway IP address
(for example, 192.168.70.125). Click Save.
Configuring management module for switch access
Complete the following initial configuration steps:
1. Connect the Ethernet port of the management module to a 10/100 Mbps network (with
access to a management station) or directly to a management station.
2. Access and log on to the management module, as described in the BladeCenter Manage-
ment Module User’s Guide. The management module provides the appropriate IP
addresses for network access (see the applicable BladeCenter Installation and User’s
Guide publications for more information).
3. Select Configuration on the I/O Module Tasks menu on the left side of the BladeCenter
Management Module window. See Figure 1-1.
Chapter 1: The Command Line Interface
2140M2420, April 2007
Alteon OS Command Reference
Figure 1-1 Switch management on the BladeCenter management module
4. You can use the default IP addresses provided by the management module, or you can
assign a new IP address to the switch module through the management module. You can
assign this IP address through one of the following methods:
Manually through the BladeCenter management module
Autom a ticall y through the IBM Director Configuration Wizard (available in
Director release 4.21)
NOTE – If you change the IP address of the GbE Switch Module, make sure that the switch
module and the management module both reside on the same subnet.
Chapter 1: The Command Line Interface 40M2420, April 2007
22
Alteon OS Command Reference
5. Enable the following features in the management module:
External Ports (I/O Module Tasks > Admin/Power/Restart > Advance Setup)
External management over all ports (Configuration > Advanced Configuration)
This setting is required if you want to access the management network through the external ports on the GbE Switch Module.
The default value is Disabled for both features. If these features are not already enabled,
change the value to Enabled, then Save.
NOTE – In Advanced Configuration > Advanced Setup, enable “Preserve new IP configura-
tion on all switch resets,” to retain the switch’s IP interface when you restore factory defaults.
This setting preserves the management port’s IP address in the management module’s memory,
so you maintain connectivity to the management module after a reset.
You can now start a Telnet session, Browser-Based Interface (Web) session, a Secure Shell session, or a secure HTTPS session to the GbE Switch Module.
Connecting to the Switch via Telnet
Use the management module to access the GbE Switch Module through Telnet. Choose
I/O Module T asks > Configuration from the navigation pane on the left. Select a bay number
and click Advanced Configuration > Start Telnet/Web Session > St a r t Telnet Session. A
Telnet window opens a connection to the Switch Module (requires Java 1.4 Plug-i n).
Once that you have configured the GbE Switch Module with an IP address and gateway, you
can access the switch from any workstation connected to the management network. Telnet
access provides the same options for user and administrator access as those available through
the management module, minus certain Telnet and management commands.
To establish a Telnet connection with the switch, run the Telnet program on your workstation
and issue the Telnet command, followed by the switch IP address:
telnet <switch IP address>
Running Telnet
Once the IP parameters on the GbE Switch Module are configured, you can access the CLI using
a T elnet connection. From the management module, you can establish a T elnet connection with
the switch.
You will then be prompted to enter a passw ord as explained on page 27.
Chapter 1: The Command Line Interface
2340M2420, April 2007
Alteon OS Command Reference
Establishing an SSH Connection
Although a remote network administrator can manage the configuration of a GbE Switch Module
via Telnet, this method does not provide a secure connection. The SSH (Secure Shell) protocol
enables you to securely log into another computer over a network to execute commands
remotely . As a secure alternative to us ing Telnet to manage switch configuration, SSH ensures
that all data sent over the network is encrypted and secure.
The switch can do only one session of key/cipher generation at a time. Thus, a SSH/SCP client
will not be able to login if the switch is doing key generation at that time or if another client
has just logged in before this client. Similarly, the system will fail to do the key generation if a
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: 3DES-CBC, DES
User Authentication: Local password authentication, Radius
The following SSH clients have been tested:
SSH 1.2.23 and SSH 1.2.27 for Linux (freeware)
SecureCRT 3.0.2 and SecureCRT 3.0.3 (Van Dyke Technologies, Inc.)
F-Secu re SSH 1.1 fo r Windows (Data Fellows)
NOTE – The Alteon OS implementation of SSH is based on SSH version 1.5 and supports SSH-
1.5-1.X.XX. SSH clients of other versions (especially Version 2) are not supported.
Chapter 1: The Command Line Interface 40M2420, April 2007

Alteon OS Command Reference
Running SSH
Once the IP parameters are configured and the SSH service is turned on the GbE Switch Module,
you can access the command line interface using an SSH connection. The default setting for
SSH access is disabled.
T o establish an SSH connection with the switch, run the SSH program on your workstation by
issuing the SSH command, followed by the switch IP address:
>> # ssh <switch IP address>
or, if SecurID authentication is required, use the following command:
>> # ssh -1 ace <switch IP address>
You will then be prompted to enter your user nam e and password.

Accessing the Switch
To enable better switch management and user accountability, three levels or classes of user
access have been implemented on the
agement functions, and screens increase as needed to perform various switch management
tasks. Conceptually, access classes are defined as follows:
User interaction with the switch is completely passive—nothing can be changed on the
GbE Switch Module. Users may display information that has no security or privacy implica-
tions, such as switch statistics and current operational state information.

Operators can only effect temporary changes on the
will be lost when the switch is rebooted/reset. Operators have access to the switch management features used for daily switch operations. Because any changes an operator
makes are undone by a reset of the swit ch, operators cannot severely impact switch operation.
Administrators are the only ones that may make permanent changes to the switch configu-
ration—changes that are persistent across a reboot/reset of the switch. Administrators can
access switch functions to configure and troubleshoot problems on the
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 surnames and passwords.
Once you are connected to the switch via local Telnet, remote Telnet, or SSH, you are
prompted to enter a password. The default user names/password for each access level are listed
in the following table.
