We were using v3 traps and things were fine, but I thought informs would be nice to have with the reliable delivery, so I changed all of my snmp-server host statements from v3 trap to v3 inform. Spectrum acted like it did not see anything. Nothing showed up in the event logs at all, not even the unknown OID stuff you normally get with an unknown trap. It was a blissfully quiet few days on the monitoring front before I realized what was happening and switched it all back to traps. Other devices that did not support informs continued to trap normally during this test.
So either Spectrum does not know how to handle informs, or there is more to turning it on than just enabling it on the router. I searched the 9.2 documents and I could not find anything about informs. -K On Sep 14, 2011, at 5:34 AM, david klein wrote: > > Can you please tell about what aspects of using SNMP Informs did not work for > you?
