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
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.
At the SCE# prompt, type more tffs0:system/prevconf/filename and press Enter.
Step 1
Displays the contents of the specified backup configuration file. Backup configuration filenames are
config.tx1-config.tx9.
Read the configuration information to make sure it is the configuration you want to restore.
Step 2
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.
At the SCE# prompt, type copy tffs0:system/prevconf/filename tffs0:system/filename and press Enter.
Step 3
Overwrites the current startup configuration file with the contents of the specified backup configuration
file.
Backup configuration filenames are config.tx1-config.tx9.
