Switch Memory and Configuration

Multiple Configuration Files

Renaming an Existing Startup-Config File

Syntax: rename config < current-filename > < newname-str >

This command changes the name of an existing startup­ config file. A file name can include up to 63, alphanumeric characters. Blanks are allowed in a file name enclosed in quotes (“ “ or ‘ ‘). (File names are not case-sensitive.)

Creating a New Startup-Config File

The switch allows up to three startup-config files. You can create a new startup-config file if there is an empty memory slot or if you want to replace one startup-config file with another.

Syntax: copy config < source-filename > config < target-filename >

This command makes a local copy of an existing startup­ config file by copying the contents of an existing startup­ config file in one memory slot to a new startup-config file in another, empty memory slot. This enables you to use a sepa­ rate configuration file to experiment with configuration changes, while preserving the source file unchanged. It also simplifies a transition from one software version to another by enabling you to preserve the startup-config file for the earlier software version while creating a separate startup­ config file for the later software version. With two such versions in place, you can easily reboot the switch with the correct startup-config file for either software version.

•If the destination startup-config file already exists, it is overwritten by the content of the source startup-config file.

•If the destination startup-config file does not already exist, it will be created in the first empty configuration memory slot on the switch.

•If the destination startup-config file does not already exist, but there are no empty configuration memory slots on the switch, then a new startup-config file is not created and instead, the CLI displays the following error message:

Unable to copy configuration to “< target-filename>”.

For example, suppose both primary and secondary flash memory contain software release “A” and use a startup-config file named config1:
