E-6 VMS User Guide
Summary
You should keep in mind the following characteristics of an SNMP Trap.
SNMP is not a “reliable” transport protocol. If the Trap message is lost
due to network issues (congestion, noise, delays, etc.), the SNMP protocol
will NOT retransmit the lost trap message.
SNMP (v1&v2) is not a secure protocol. It is not difficult to eavesdrop or
spoof messages. Isolating SNMP traffic from end-user channel is
recommended.
VMS will generate a trap message for each destination entered. Entering
10 trap destinations, for example, will generate 10 trap messages for each
event.
Only a VMS server in Active mode will generate trap messages. A
redundant VMS server in stand-by mode will not generate or send a trap
message until it is switched to Active mode for example the Primary
server failure is detected.
At this time there is no VMS SNMP agent in VMS. An SNMP Manager
cannot poll VMS for status or configuration detail information.
Current trap uses SNMP v1.
