Installing VIA
Users can download VIA from a URL provided to them by their IT department and install it on their computers.
Alternatively, you can install VIA on users computer using SMS (Systems Management Server) or other similar
mechanisms.
Upgrade Workflow
VIA checks for upgrade requirements during the login phase. There are two types of upgrade process:
z Minimal Upgrade—This type of upgrade is initiated for bug fixes and some minor enhancements which
requires only the client to be upgraded. When a VPN session is active the upgrade binary is downloaded by
VIA from the controller. After the active VIA connection is terminated, the upgrade process is started and the
client is upgraded. This type of upgrade does not require a system reboot.
z Complete Upgrade—This requires an upgrade to VIA and its underlying network drivers. This type of upgrade
requires a system reboot. VIA downloads the upgrade binary from the controller and displays a message about
upgrade process. The user can choose to proceed or cancel the upgrade process. If the user chooses to upgrade,
a system reboot is required. If the user cancels the upgrade, VIA will prompt the user for an upgrade every
time it attempts to connect.
Configuring the VIA Controller
VIA configuration requires that you first configure VPN settings and then configure VIA settings. See Chapter 15,
“Virtual Private Networks” on page347 for information on configuring VPN settings on your controller.
