Saving and Restoring the 4300T Configuration The 4300T stores all configuration information for the system in a series of
individual files that reside in local flash memory. These files are read at boot
time to determine the configuration identity of the 4300T and then stored in
RAM as “running” state. As you configure the 4300T the submit command
writes the configuration changes to both RAM and flash so that the files stored
in flash are always up to date with the running state of the system.
The 4300T provides a utility that enables you to copy the individual
configuration files stored in flash to a single, consolidated backup file. This
single file ca n then be us ed as a backu p for the entire system and restored at a
later date if necessary. Multiple backup files with different system
configurations can also be created and stored locally in the 4300T or on remote
TFTP servers.
Backup file operations are performed in the 4300T CLI using the ewn
command.
The ewn Command
The syntax for the
ewn
command is as follows:
USAGE:
ewn help|list
ewn save|load|delete [file name]
ewn upload|download [file name] [ip address]
where file name must use extension .conf1 or .conf2
Note No more than 2 backup files can be stored in the 4300T’s flash due to size
constraints. Also, it is recommended that you create a backup file after any
configuration changes are made to the 4300T. This is to prevent the loss of any
configuration changes made since your last backup in the event that you must
restore the system configuration.
