Dear rav.kaminski,
What do you think is good about the "good" one and bad about the "bad" one ? They look like normal SNMP sessions though to different SNMP Servers. Neither apply to your configuration that you shared, maybe you are just looking at the wrong sessions in your session log ?
Edited :
Also you can't have the same "source-address" on two different devices ( 192.168.111.1 ) that are on the same network and using the same SNMP Server.
