Using TFTP to Download the Configuration
ExtremeWare 7.2e Installation and User Guide 321
Using TFTP to Download the Configuration
You can download ASCII files that contain CLI commands to the switch to modify the switch
configuration. Three types of configuration scenarios that can be downloaded:
• Complete configuration
•
Incremental configuration
• Scheduled incremental configuration
If you load a configuration from a different model, you can safely write the correct configuration over
the unsupported configuration.
Downloading a Complete Configuration
Downloading a complete configuration replicates or restores the entire configuration to the switch. You
typically use this type of download in conjunction with the
upload configuration
command, which
generates a complete switch configuration in an ASCII format. As part of the complete configuration
download, the switch is automatically rebooted.
To download a complete configuration, use the
download configuration
command using the
following syntax:
download configuration [<ip address> | <hostname>] <filename>
After the ASCII configuration is downloaded by way of TFTP, you are prompted to reboot the switch.
The downloaded configuration file is stored in current switch memory during the rebooting process,
and is not retained if the switch has a power failure.
When the switch completes booting, it treats the downloaded configuration file as a script of CLI
commands, and automatically executes the commands. If your CLI connection is through a Telnet
connection (and not the console port), your connection is terminated when the switch reboots, but the
command executes normally.
Downloading an Incremental Configuration
A partial or incremental change to the switch configuration may be accomplished by downloaded
ASCII files that contain CLI commands. These commands are interpreted as a script of CLI commands,
and take effect at the time of the download, without requiring a reboot of the switch.
To download an incremental configuration, use the following command:
download configuration [<ip address> | <hostname>] <filename> {incremental}
Do not download an incremental configuration when you have time-critical applications running. When
you download an incremental configuration, the switch immediately processes the changes, which can
affect the processing of other tasks. We recommend that you either download small incremental
configurations, or schedule downloads during maintenance windows.
