Hi Dave,
I was followintg your suggestions. At this moment, my snmpd.conf file
looks like:
snmpd.conf
=================%<===============================================
createUser madeiracomm MD5 madeiramadeira DES madeiramadeira
trapsess -v3 -u usmuser -a MD5 -A md5passwd -x DES -X despasswd
localhost
agentSecName usmuser
monitor -S -u usmuser -r 3 -e linkUpTrap "Generate linkUp"
ifOperStatus != 2
monitor -S -u usmuser -r 3 -e linkDownTrap "Generate linkDown"
ifOperStatus == 2
NotificationEvent linkUpTrap IF-MIB::linkUp ifIndex ifAdminStatus
ifOperStatus
NotificationEvent linkDownTrap IF-MIB::linkDown ifIndex ifAdminStatus
ifOperStatus
=================%<===============================================
snmptrapd.conf

This log occurs when I unplug the cable from the Network Interface Card.
It seems as if an alarm has reached (snmp_alarm: run alarm 2). However,
there is some problems with the 'agentx'.
In my computer, the folder /var/agentx does not exist. Shall I compile
the net-snmp with any particular option?
Thanks a lot for your help!
Regards,
Ricardo
