General
Out-of-Band management and switching serves to control satellite modems that
either utilize a primary data interface that is not IP based, or do not possess the
Vipersat technology for InBand operation. All that is required is that the modem
has an Ethernet IP interface that is routable via a default gateway, and that the
SNMP MIB for the interface has a driver implemented in the VMS. Out-of-
Band management provides switching capability for synchronous serial or bulk
encrypted applications, and extends the family of modems that can be controlled
by the VMS.
This chapter describes integrating Out-of-Band modem units into a VMS-
controlled satellite network.
Overview
In a Vipersat network, Out-of-Band units typically use Simple Network
Management Protocol (SNMP) for management and control by the VMS. These
are modems that are supported by the VMS SNMP Modem Manager. It is possi-
ble to utilize modems that are supported by the VMS Vipersat Manager
(referred to as Vipersat-enabled) as Out-of-Band units. However, because these
modem types possess integrated Vipersat technology and offer a primary data
interface that is IP based, they are more efficiently used as InBand units, and
require only a single carrier out of a remote terminal.
Possible considerations for using Vipersat-enabled units for OOB include:
• Very simple configurations for applications that do not require automatic
switching capability.
