Sorry, I don't see any highlighted numbers, as these were filtered out
by Mailman/MimeDel ;-)

The MIB defines when to send a trap (for example, if an object of the
MIB changes its value, or if a new entry is added to a table). It
depends on the trap definition, which values the agent has to include in
the trap.

Maybe with one of the examples. I think all of them will send a trap at
startup.

snmp++ comes with a receive trap example, that you can use for the first
steps. It will just print out the trap contents.
