I am trying to receive SNMP traps from a Cisco Wireless LAN Controller. I installed the SNMP_TA app, added a MIB file (SNMPv2-MIB) from Cisco, and originally setup using port 162.

I then added aN iptables rule: iptables -t nat -A PREROUTING -i eth0 -p udp --dport 162 -j REDIRECT --to-port 8166 and changed the data input to be equal to 8166. There are no other rules in my iptables. I then did a search for index=_internal error ExecProcessor snmp.py and saw no errors, but I see no SNMP data when I search for sourcetype=SNMP_TA . Additionally when I do a TCPdump for the host that is supposed to be sending the data, I see the traps. Below are my input settings as they exist now: SNMP Mode = Listen for traps IP Version 6 = Not checked SNMP Version = 2c Community String = XXXXXX MIB Names = SNMPv2-MIB Response Handler = BLANK Response Handler Arguments = BLANK TRAP listener host = XXXXX.XXX.com TRAP listener port = 8166 Reverse DNS lookup of trap sources = Not checked Set sourcetype * = Manual Source Type = cisco:asa Host field value = localhost.localdomain Index = access ...
