To remove a configuration command from the running-config, use the no form of the command.
The following example illustrates how to remove all DNS settings from the running configuration.
SCE(config)#no ip name-server
Restoring a Previous Configuration
When you save a new configuration, the system automatically backs up the old configuration in the
directory tffs0:system/prevconf/. Up to nine versions of the startup configuration file are saved, namely
config.tx1-config.tx9, where config.tx1 is the most recently saved file.
Use the CLI command more to view the old startup configuration files. See How to Display File
Contents, page 4-8
Restoring a previous startup configuration means renaming the file so it overwrites the startup
configuration (config.txt ) file.
Since the restore operation overwrites the current configuration file, you cannot undo the configuration
restore operation. It is recommended to always backup the current configuration file first.
Step 1 At the SCE# prompt, type more tffs0:system/prevconf/filename and press Enter.
Displays the contents of the specified backup configuration file. Backup configuration filenames are
config.tx1-config.tx9.
Step 2 Read the configuration information to make sure it is the configuration you want to restore.
Be sure that you are restoring the proper configuration file, since the restore operation is not reversible.
It is recommended to always backup the current configuration file first.
Step 3 At the SCE# prompt, type copy tffs0:system/prevconf/filename tffs0:system/filename and press Enter.
Overwrites the current startup configuration file with the contents of the specified backup configuration
file.
Backup configuration filenames are config.tx1-config.tx9.
