Observer Suite: SNMP Management
level of activity, or other condition. SNMP Extension collects incoming trap messages
constantly.
“Trap” and “trap message” are used interchangeably.
To receive trap messages with SNMP Management Console, SNMP Management
Console's IP address must be included in the trap configuration table of the SNMP agent.
Trap configuration is usually separate from general SNMP configuration.
If you configure one but not the other, you may be able to poll the SNMP
agent, but receive no trap messages.
The SNMP agent doesn’t expect confirmation for trap messages. If the message doesn’t
reach its destination, SNMP Management Console has no way of knowing the message
was sent, and the agent has no way of knowing whether a message was received.
Under normal circumstances most of the trap messages do reach their
destinations. The limitation of traps comes from the lack of verification
capabilities built into the relevant RFC specifications.
The MIB Editor
The MIB Editor is where MIBs are compiled and MIB objects are placed in requests to
create SNMP Management Console lists, charts, tables, forms, and traps.
• MIB—a MIB is a text file in Abstract Syntax Notation One (ASN.1) format, which
describes in a structured way the objects an SNMP device supports.
• Compiled MIBs—a compiled MIB is a binary file created from a MIB file in
preparation for creating requests to be submitted to an SNMP agent.
