Unable to configure ISE to receive SNMP traps

orp — Fri, 01 Mar 2019 10:57:54 GMT

Hi, I'm trying to have ISE (2.3) receive info from my switches by receiving SNMP traps. I've configured the switches to send the traps to ISE, and I even see them in Wireshark, but I get an ICMP port unreachable for each one (port 162). I've followed several configuration guides but still no success.

Any ideas?

Thanks

Apparently I had to check the SNMP trap flag in administration->system->deployment->profiling configuration. I definitely went over a large number of configuration docs and didn't come across this.

Anyway, while I don't get the ICMP port unreachable anymore I don't see any effect of the traps on ISE. No new information is added to the UI. Is there a simple trap that can show me that the entire SNMP traps mechanism works?

I just upgraded to ISE 2.4 and it seems to work much better. I get numerous devices discovered and much more information obtained from each.
