Saving and Restoring the V 2 IU 4350
Configuration
The V 2 IU 4350 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 4350 and then stored in
RAM as “running” state. As you configure the 4350 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 4350 provides a utility that enables you to copy the individual
configuration files stored in flash to a single, consolidated backup file. This
single file can then be used as a backup 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 4350 or on remote
TFTP servers.
Backup file operations are performed in the 4350 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
The ewn command can be used with a local terminal connection or remotely
using SSH.
Note No more than 2 backup files can be stored in the 4350’s flash due to size
constraints. Also, it is recommended that you create a backup file after any
configuration changes are made to the 4350. 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.
