Chapter 6. Configuring The Switch Module Through The Telnet Interface; Remotely Managing The Ethernet Switch Module - IBM BladeCenter Installation And User Manual

Chapter 6. Configuring the switch module through the Telnet
interface
Your switch module supports a management interface that you can use to set up
and control your device over the network using the TCP/IP Telnet protocol. You can
use this facility to perform many basic network management functions. In addition,
you can use the Telnet interface to configure the switch module for management
using an SNMP-based network management system. This chapter describes how to
use the Telnet interface to access the switch module, change its settings, and
monitor its operation.
Important: Before you configure your Ethernet switch module, be sure that the
management modules in your BladeCenter unit are properly configured. In addition,
to access and manage your Ethernet switch module from an external environment,
you might need to enable certain features, such as the external ports and external
management over all ports. See the applicable BladeCenter Installation and User's
Guide publications on the IBM BladeCenter Documentation CD for more
information.
In addition to reviewing the publications in this library, be sure to review the IBM
BladeCenter Planning and Installation Guide located at
http://www.pc.ibm.com/eserver/bladecenter on the World Wide Web for information
to help you prepare for system installation and configuration.

Remotely managing the Ethernet switch module

The Ethernet switch module supports two remote-access modes for management
through Ethernet connections. You can select the mode that is best suited for your
BladeCenter environment. The Ethernet switch module has an internal Ethernet
path to the management module and the four external Ethernet ports on the switch
module.

mode, the remote-access link to the management console must be attached to
the 10/100 Mbps Ethernet port on the management module. With this mode, the
IP addresses and SNMP parameters of the Ethernet switch modules can be
automatically assigned by the IBM Director BladeCenter Deployment Wizard or,
you must manually assign them through the BladeCenter Management and
Configuration Program. This mode enables the system administrator to provide a
secure LAN for management of the BladeCenter subsystems separately from the
data network.
Important: With this mode, the Ethernet switch module does not respond to
remote-management commands through the four external Ethernet ports on the
switch module.

BladeCenter Documentation CD for additional instructions for configuring the
Ethernet switch module for this mode of operation.
