General
This chapter describes using VMS to configure Vipersat network modems.
Configuration of modem parameter files is accomplished using the Parameter
Editor. The Parameter Editor, as used from the VMS, performs the same func-
tions as the Parameter Editor accessed via Vipersat’s VLoad utility. The uses of
the Parameter Editor in VMS and VLoad differ, however, in the way the edited
parameters are stored and applied.
For example, once a modem/router parameter has been changed by the VMS
(online editing), clicking the OK button on the edit screen causes the change to
be implemented immediately in the modem. The same change made using
VLoad (offline editing) will not be implemented in the modem until the modi-
fied parameter file is uploaded or “put” to the subject modem/router.
Several parameter modifications can also be made from the Parameter View
interface within ViperView (figure 4-1) by clicking on a setting and editing it.
Note that the number of settings presented here is not as comprehensive as what
is provided within the Parameter Editor.
Alternatively, parameter changes may be made directly to the modem using
either a console, Telnet, or HTTP connection, rather than using the VMS. Refer
to the modem’s documentation for details on configuring modem equipment
using one of these methods. The VMS will generate a log event to inform the
operator/user that one or more parameters for that modem have been changed
by an external source—another VMS client, or via the WSI, for example—since
the last parameter change by this user account.
