4 Maintaining configurations and
firmware
This chapter contains procedures for maintaining switch configurations and installing firmware and
consists of the following sections:
• Maintaining configurations , page 75
• Maintaining firmware , page 78
• Troubleshooting firmware downloads , page 86
Maintaining configurations
It is important to maintain consistent configuration settings on all switches in the same fabric, because
inconsistent parameters (such as inconsistent PID formats) can cause fabric segmentation. As part of
standard configuration maintenance procedures, HP recommends that you back up all important
configuration data for every switch on a host computer server for emergency reference.
The following sections contain procedures for basic switch configuration maintenance.
Displaying configuration settings
The switch configuration file comprises four sections, and is organized as follows:
• The Boot Parameters section contains variables such as the switch's name and IP address.
• The Licenses section lists the licenses that are active on the switch.
• The Chassis Configuration section contains configuration variables such as diagnostic settings, fabric
configuration settings, and SNMP settings.
• The Configuration section contains licensed option configuration parameters.
To display configuration settings, connect to the switch, log in as admin, and enter the
configshow
command at the command line. The configuration settings vary depending on switch model and
configuration.
Backing up a configuration
Keep a backup copy of the configuration file in case the configuration is lost or unintentional changes are
made. You should keep individual backup files for all switches in the fabric. You should avoid copying
configurations from one switch to another.
The following information is not saved in a backup:
•
dnsconfig
information
• passwords
You must have a valid account on the FTP server where the backup file is to be stored.
You can specify the use of secure file copy (scp) during the procedure. For instructions on configuring the
use of scp by default, see ” Configuring secure file copy ” on page 69.
