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.

BMD00007, November 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(s) through its internal port 15 (MGT), which you can access through the Ethernet port on each 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 four external 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 applicable BladeCenter Installation and User’s Guide publications for more information).

NOTE – Support for both management modules is included within the single management port (MGT). The MGT port dynamically connects to the active management module.

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

 The Command Line Interface BMD00007, November 2007

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.

The Command Line Interface

 21BMD00007, November 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.

 The Command Line Interface BMD00007, November 2007

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 > Sta r t Telnet Session. A Telnet window opens a connection to the Switch Module (requires Java 1.4 Plug-in).

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 password as explained on page 26.

The Command Line Interface

 23BMD00007, November 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 Technolo gies, 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.

 The Command Line Interface BMD00007, November 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>

If SecurID authentication is required, use the following command:

>> # ssh -1 ace <switch IP address>

You will then be prompted to enter yo ur user name and password.

Alteon OS Command Reference

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.

GbE Switch Module. Levels of access to CLI, Web man-

 Operators can make temporary changes on the

GbE Switch Module. These changes are 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 switch, 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

GbE Switch Module.

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.

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

“Setting Passwords” on page 43.

Setup Versus CLI

Once the administrator password is verified, you are given complete access to the switch. If the switch is still set to its factory default configuration, the system will ask whether you w ish to run Setup (see Chapter 2, “First-Time Configuration”), a utility designed to help you through the first-time configuration process. If the switch has already been configured, the Main Menu of the CLI is displayed instead.
