I'm trying to collect simple logs from Cisco devices using netsnmp with SNMP v3.
I can get the messages to appear in my snmptrapd, but I have to manually add the EngineID to for them to talk. E.g., until I do so, I see messages like:
usm: no match on engineID (80 00 00 09 03 00 3C 01 02 03 04 05 usm: no match on engineID (80 00 00 09 03 00 3C 01 02 03 04 05 )
Then I have to go into /etc/snmp/snmptrapd.conf and manually add the engine in a new createUser line.
I will have to add some 200 devices shortly and there's going to need to be a regular procedure to add new ones. Is there a way to improve this situation without losing encryption?
