Backup and Restore

The VPN Concentrator 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 of the VPN Concentrator and then stored in RAM as running
state.
The VPN Concentrator provides a utility that enables you to copy the individual
configuration files stored in flash to a single system configuration file. This configuration
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 VPN Concentrator or on remote TFTP servers.
The CLI provides access to these files and to the utility that enables you to copy them. The
CLI can be accessed with a local terminal connection or remotely using SSH.

Connecting to the CLI

Follow these guidelines when connecting to the CLI:
1. Use a straight-through or null modem cable to connect to the console port of the VPN
Concentrator (Note: The 5300xxx models use a null modem cable).
2. Use a terminal emulator such as HyperTerminal set to a baud rate of 9600, 8 data bits, 1
stop bit, NONE for flow control. Alternatively, you can connect to the VPN
Concentrator remotely using SSH.
3. Log on as root and enter the password provided by ShoreTel support.

VPN Concentrator Installation and Configuration Guide
Note:
Only two backup files can be stored in the VPN Concentrator' s flash
memory because of size constraints. Also, it is recommended that you
create a backup file after any configuration changes are made to the VPN
Concentrator. 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.
