Maintaining Configurations and Firmware
This chapter contains procedures for maintaining switch configurations and for installing firmware.
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, it is recommended 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 three 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
In case the configuration is lost or unintentional changes are made, keep a backup copy of the
configuration file (if using a SilkWorm 12000 or 24000 with two domains, configuration files–one for
each logical switch), which is what gets saved when you enter the configUpload command. 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
