Configuration Backup/Restore

This chapter describes the process for backing up your user settings (configuration) from the AES-100 onto your computer and how to restore them to the AES-100.

The AES-100 uses TFTP for configuration backup/restore through its built -in TFTP server. You can use any TFTP client to connect to the AES-100.

Do not turn off the AES-100 during the updating process, as it may corrupt the firmware and make your

AES-100 unusable.

9.1Configuration Files of the AES-100

The AES-100 uses configuration files to store the user’s settings, so they can be applied the next time the A ES-

100 is booted. The AES-100 has the following seven important configuration files:

initadsl =	The configuration file for ADSL ports.
resolve =	The configuration file for IP parameters.
initbridge =	The configuration file for bridge settings.
password =	The configuration file for the console and Telnet password.
services =	The configuration file for IP services.
initether =	The configuration file for Ethernet port settings.
snmpinit =	The configuration file for SNMP settings.

9.2Control Files Used In TFTP Operation

TFTP is a simple file transfer protocol and lacks a password checking feature. The AES-100 requires users to transfer a special file to achieve authentication functions. This file contains the SNMP’s write community string. In addition, there may be more than one configuration file to restore into the AES -100, so it is necessary to tell the AES-100 the beginning and end of the list of configuration files you want to restore. This way the AES -100 can know when to write the restored configuration files to nonvolatile memory. There are three control files used in TFTP operation:

tftplock.key = This file contains the SNMP write community string (password).

tftpupdt.beg = An empty file (with no content). Acts as a mark of the beginning of the restore process, used only in restoration.

tftpupdt.end = An empty file (with no content). Acts as a mark of the end of the restore process, used only in restoration.
