We modified our rules to strip the SNMPWe created a catch all traps event rule to collect all SNMP traps received as events. We discovered our network device that will send us SNMP Traps. Here is my nf # Example configuration file for snmptrapd We created an Ubuntu server to send test SNMP traps from. Is it possible to configure snmptrapd to accept all traps by authenticated users without specifying engineID? And I can see trap arrives on interface in wireshark, but snmptrapd does nothing.

But when I configure cisco router to send me linkDown trap it uses MAC address with some extra bytes as engineID.

I'm already have such script and it works with snmp v1, v2c traps and with snmpv3 traps but only when I specify engineID explicitly both in config and in command sending trap. I'm trying to make some perl script to handle snmp traps. I'm using snmptrapd on linux from net-snmp package.
