Introduction
This appendix describes the use of SNMP traps by the Vipersat Management
System (VMS). SNMP traps enable the VMS to capture significant network
events, then generate an SNMP message reporting the event. In a VMS
controlled satellite system, this configuration has several advantages:
• The VMS system, using its existing network monitoring capability, acts as
a central collection point for all changes to the satellite network status and
provides a single source for SNMP events reported for the satellite
network. Individual network devices are not required to generate SNMP
traps thereby reducing network overhead bandwidth.
• The VMS collects network changes and status as they occur and as they
are reported by the satellite network’s modem/routers as part of the normal
VMS management and control function.
• Only events defined by the Vipersat MIB are sent as SNMP traps. This
reduces the requirement to have each device transmit an SNMP trap as its
status changes thereby reducing network overhead bandwidth
requirements.
Note: Since VMS only collects and reports SNMP events from the satellite
network and it is not the source of the event, you cannot query the VMS
for additional information about an SNMP trapped event.
