As far as I know, you have to implement the queue yourself. The solution I
used for traps generated by my own code was to append traps, in the form
of snmptrap commands, to a script that I could execute later when the
interface
came up.
The problem is identifying when you should actually send
. That is, I gave the configure
script --with-cflags=-1 -O1.
So the crashes seem to be related to using the legacy g77 fortan
compiler and C optimization level 2.
Cheers.

We've been trying to get Net-SNMP 5.4 to build without

It appears not to take no for an answer.

Mbps interfaces (on Linux 2.4) were all reporting 10 Mbps.
Does the interface command in snmpd.conf still work for the
case where the new code doesn't successfully detect the speed?

Last I looked, Net-SNMP just guessed at ethernet interface speeds. It
used to always guess 10 Mbps, but at some point it started to guess 100
Mbps. It does not dynamically detect the speed. You can change what
the agent reports by telling the agent the interface speed using the
interface

If you don't need the agent to send any other traps, you can just
remove the trapsink/informsink links from the configuration.
Then send your traps yourself.
