Hi all, I am trying to configure my computer (an Ubuntu Computer with net-snmp version 5.4) to send traps whenever the network interface is switched and/or off and when it is connected and disconnected.
Until now, I have not managed to reveice this traps in v3, although I'm receiving them in v2. Follwing, I will attach my configuration file, as well as the log of the snmptrap. snmpd.conf -------------------%<--------------------------------------------------- rwcommunity usmuser # SECTION:

be extracted from the log, the trap for snmpv2 is correctly received, but the trap for v3 is not received because there is some problem when authenticating the Security User Name. Do you have any clue about this problem? Thanks in advance!
