Chapter 5: Saving and Restoring the 4200
Configuration
The 4200 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 4200 and then stored in RAM as “running”
state. As you configure the 4200 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 4200 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 4200 or on remote TFTP servers.
PLEASE note: No more than 2 backup files can be stored in the 4200’s flash due to
size constraints. Also, it is recommended that you create a backup file after any
configuration changes are made to the 4200. 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.
Backup file operations are performed in the 4200 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.
A. Use a NULL modem cable to connect to serial port 1 of the 4200
B. Use a terminal emulator such as Hyperterminal set to a baud rate of 115200,
8, 1 and non (databits, stop bits and parity)
Alternatively you can connect to the 4200 remotely using SSH:
A. Logon as root
B. Enter the password
