Updating VPN3002 Hardware Client software in an environment with a large number of devices in different locations can be a formidable task. For this reason, the VPN 3000 Series Concentrator lets administrators at a central location automatically update software/firmware for VPN 3002 Hardware Clients deployed in diverse locations.
When you enable Client Update, upon connection the Concentrator sends an IKE packet that contains an encrypted, user-defined message that notifies VPN 3002 hardware clients about acceptable versions of executable system software and their locations. If the VPN 3002 is not running an acceptable version, its software is automatically updated via TFTP.
To use client update, you need to have an TFTP server that can handle the volume and frequency of updates that your network requires. We recommend that you locate this server inside your network. The client update facility sends notify messages in batches of 10 at 5-minutes intervals.
You configure parameters that specify the acceptable versions of software and their locations. Updates are supported per group. This means that all members of a group can obtain the same updates from the same server at approximately the same time.
The Concentrator logs event messages at the start of the update. When the update completes, the client reboots automatically.
This section of the VPN 3000 Concentrator Series Manager lets you configure the client update feature (for the VPN 3002 Hardware Client only).
This screen let you disable or enable client update.
Uncheck or check the box to disable or enable client update (by default, client update is enabled).
To apply your change to client update, click Apply. This action includes your entry in the active configuration. The Manager returns to the Configuration | System | Client Update screen.
To save the active configuration and make it the boot configuration, click the Save Needed icon at the top of the Manager window.
To discard your entries, click Cancel. The Manager returns to the Configuration | System |Client Update screen, and the settings are unchanged.
This screen lets you add, modify, or delete client update entries.
The update entry list shows the configured client update entries. Each entry shows the platform and acceptable software/firmware versions. If no updates have been configured, the list shows --Empty--.
To configure and add a new client update entry, click Add. The Manager opens the Configuration | System | Client Update | Entries | Add screen.
To modify parameters for a client update entry that has been configured, select the entry from the list and click Modify. The Manager opens the Configuration | System | Client Update | Modify screen.
To remove a client update entry that has been configured, select the entry from the list and click Delete. There is no confirmation or undo. The Manager refreshes the screen and shows the remaining entries in the list.
To save the active configuration and make it the boot configuration, click the Save Needed icon at the top of the Manager window.
These screens let you configure and change client update parameters.
Enter the client type you want to update. Your entry must be vpn3002, including case and spacing.
Enter the URL for the software/firmware image. This URL must point to a file appropriate for this client.The format of the URL is: TFTP://server_address:port/directory/filename. All parts of the URL are optional except the protocol (TFTP), and the server address.
Enter a comma separated list of software or firmware images appropriate for this client. These caveats apply:
To add this client update entry to the list of configured update entries, click Add. Or, to apply your changes, click Apply. Both actions include your entry in the active configuration. The Manager returns to the Configuration | System | Client Update screen. Any new entry appears at the bottom of the Update Entries list.
To save the active configuration and make it the boot configuration, click the Save Needed icon at the top of the Manager window.
To discard your entries, click Cancel. The Manager returns to the Configuration | System | Client Update screen, and the Update Entries list is unchanged.
