Configurations across a fabric

To save time when configuring fabric parameters and software features, you can save a

configuration file from one switch and download it to other switches of the same model type, as

shown in the following procedure.

Do not download a configuration file from one switch to another switch that is a different model or

firmware version, because it can cause the switch to fail. If you need to reset affected switches,

issue the configDefault command after download is completed but before the switch is enabled.

Once enabled with a duplicate domain ID, the switch will then become segmented.

Downloading a configuration file from one switch to another same

model switch

1. Configure one switch.

2. Use the configUpload command to save the configuration information. Refer to “Configuration

file backup” on page 182 for more information.

3. Run configDefault on each of the target switches, and then use the configDownload command

to download the configuration file to each of the target switches. Refer to “Configuration file

restoration” on page 184 for more information.

Security considerations

Security parameters and the switch identity cannot be changed by the configDownload command.

Parameters such as the switch name and IP address (lines in the configuration file that begin with

“boot”) are ignored. Security parameters (lines in the configuration file that begin with “sec”), such

as secure mode setting and version stamp, are ignored.

For more detailed information on security, refer to Chapter 6, “Configuring Protocols”.

Configuration management for Virtual Fabrics

You can use the configUpload -vf or configDownload -vf command to restore configurations to a

logical switch. The -vf option only restores the Virtual Fabrics configuration information on to a

switch of the same model.

The Virtual Fabric configuration on the switch defines all of the logical switches allowed and

configured for a particular platform.

Uploading a configuration file from a switch with Virtual Fabrics

enabled

The configUpload command with the -vf option specifies that configuration upload will upload the

Virtual Fabric configuration instead of the non-Virtual Fabric configuration information.

You must specify a filename with the configUpload -vf command. It is recommended not to use

config.txt for a filename as this can easily be confused with a normal uploaded configuration file.
