Re: Immediate notifications for interfaces ?

It depends on what you mean by "immediate".

The DisMan Event MIB support would allow the agent to
check the status of network interfaces on a regular basis,
and report when anything changes.   See snmpd.conf(5)
for details.
   The polling frequency can be specified as part of the
"monitor" command, but the limiting factor would probably
be the implementation of the IF-MIB itself.

If you're looking for a *real* immediate notification, then
you really have to have some form of hook into the interface
driving code itself.   Patch #1759178 might be of interest
to you here.
