Try running "monitor -S ...."
Hi,
Thanks for the info.
So here's the config now:
notificationEvent linkUpTrap linkUp ifIndex ifAdminStatus ifOperStatus
notificationEvent linkDownTrap linkDown ifIndex ifAdminStatus ifOperStatus
monitor -S -r 5 -e linkUpTrap "Generate linkUp" ifOperStatus != 2
monitor -S -r 5 -e linkDownTrap "Generate linkDown" ifOperStatus == 2
And here are the commands executed:
484 /etc/init.d/snmpd stop
485 /etc/init.d/snmpd start
And this how the traps are received:
/usr/sbin/snmptrapd -Lf ~/trap_log.txt -F "%02.2h:%02.2j TRAP:%W from %b %P %v\n"
As you can see, there is still a bunch of msgs received at the startup:

Curiously the following msgs - part of the same bunch - do not have
the ifOperStatus, ifAdminStatus and ifIndex fields:

[No other msgs recevied]
Minutes later I unplugged and plugged back an interface (eth2) cable
and the correct link down/up traps were received. Looks good from now
on.

The problem is with the quantity of traps received at the start up of
the daemon, all bearing the same time stamp, making them practically
worthless that is, if they actually picture an historical trace of
events.
Thanks.
