I don't understand the question.  SIA never sent traps.  He populated a MIB
that the MLM queried and MLM sent the trap.  And no MLM function has been
lost or changed in NetView.

James,
I believe the old "System Monitor" agent was a multi-plexing agent.
It handled all of the multi-plexing of messages between different
ports.

Was this function lost when they split it up (SIA, MLM, DLM)?

Regards,

Gary Boyles
