Switch Memory and
Configuration
Storing and Retrieving Configuration Files. You can store or retrieve a
backup copy of the startup-config file on another device. For more informa-
tion, see appendix A, "Transferring an Operating System or Startup-Config
File"
Using the CLI To Implement
Configuration Changes
The CLI offers these capabilities:
â– Access to the full set of switch configuration features (For a complete
listing, see the Command Line Interface Dictionary.)
â– The option of testing configuration changes before making them perma-
nent
How To Use the CLI To View the Current Configuration Files. Use
show commands to view the configuration for individual features, such as port
status or Spanning Tree Protocol. However, to view either the entire startup-
config file or the entire running-config file, use the following commands:
â– show startup-config: Displays the current startup-config file.
â– write terminal: Displays the current running-config file.
Note The show startup-config and write terminal commands display the configuration
settings that differ from the switch’s factory-default configuration.
How To Use the CLI To Reconfigure Switch Features. Use this proce-
dure to permanently change the switch configuration (that is, to enter a change
in the startup-config file).
1. Use the appropriate CLI commands to reconfigure the desired switch
parameters. This updates the selected parameters in the running-config
file.
2. Use the appropriate
show commands to verify that you have correctly
made the desired changes.
3. Observe the switch’s performance with the new parameter settings to
verify the effect of your changes.
4. When you are satisfied that you have the correct parameter settings, use
the
write memory command to copy the changes to the startup-config file.
