 Description   

there is no real documentation around snmp v3 traps in zabbix and how to set it up
for example net-snmp at least in Centos 7 is not supporting AES 256Bit encryption only 128 in zabbix we will not see warnings about it it will just not work

http://snmp.com/snmpv3/snmpv3_aes256.shtml
also the configuration in snmptrapd.conf is a bit different

createUser -e <engineid> <user> SHA <key> AES <key>
authUser log,execute <user>
perl do "/usr/bin/zabbix_trap_receiver.pl";

 
authUser needs to have the execute option else the perl script will not be executed also the engineid is the engineid for the traps not the engineid configured on the switch.
there is also the option to send traps or informs with informs sending an ack back to the switch

I've also hit this bug on CentOS7 https://bugzilla.redhat.com/show_bug.cgi?id=1468084 which limited me from running the latest trap script properly (workaround works), I will document it in the blog post.

Hi Patrick, is the right way to set it ?

Can you provide a test command like the one reported in https://www.zabbix.org/wiki/Start_with_SNMP_traps_in_Zabbix as well ?

regards

This must be a MASSIVE new page with information, or am I missing something after 2.5 years? 😅

The documentation for SNMP trap monitoring has been updated for 6.0, 6.2, 6.4.

Main changes:

  • Bash trap receiver option added
  • SNMP-version specific comments added for v1/2 and v3.
