򐂰 External management over all ports
Use this field to enable or disable external configuration management of this module.
When this field is set to Disabled, only the Management Module ports can be used to
change the configuration on this module (in other words, out-of-band management). When
the field is set to Enabled, all ports (including internal, external, and Management Module
ports) are enabled for management and you must follow certain rules.
See 5.3, “In-depth management path discussions” on page 55 for details about using this
setting to define IGESM management paths.
򐂰 Preserve new IP configuration on all resets
Use this field to specify whether you want the user-defined IP configuration to be
preserved when the module’s factory defaults are restored or when a reset is initiated by a
source other than the Management Module. If this field is set to Enabled, be sure a valid IP
configuration is entered for this switch module in the Management Module settings for this
switch. If this field is set to Disabled, the factory default IP configuration will become active
when the switch factory defaults are restored or when a switch reset is initiated by a
source other than the Management Module. In this case, any user-defined IP configuration
for the IGESM stored on the Management Module will not be used.
Note that although setting this value to Disabled allows the IGESM to use its NVRAM
stored IP information on subsequent reboots of the IGESM, when the Management
Module reboots it will still place its version of the IGESM IP address on to the IGESM.
Therefore it is strongly recommended that you leave this setting at Enabled to prevent the
different IP information from being utilized when the IGESM reloads as opposed to when
the Management Module reloads.
The only way to effectively utilize this setting as Disabled is to store the same information
in the Management Modules IGESM settings as is stored in the NVRAM of the IGESM.
This ensures that no matter which reloads (the Management Module or the IGESM), the
correct IP information will be on the IGESM.
IGESM firmware download
In this section, we load the latest version of the switch module’s firmware.
Determining the level of Cisco switch software
After you install the Cisco Switch Module in your BladeCenter unit, make sure that the latest
Cisco switch operating system is installed on the module. To determine the level of the Cisco
switch operating system software that is installed on the switch module:
1. Log on to the IGESM Command Line Interface.
2. Run the show version command.
3. Review the version information returned for current revision.
For the bulk of this project, we used the Cisco Systems IGESM firmware build 12.1 [14] AY.
Obtaining the latest level of switch software
To determine the latest level of the Cisco switch operating system software that is available
from IBM, complete the following steps:
1. Go to http://www.ibm.com/pc/support/site.wss/
2. Click Downloads and drivers.
3. In the Downloads and drivers window Quick path field, enter the switch machine model
number (for example, 8832-21x) and click Go. A Results window opens, displaying a list of
links to the latest available software.
