Ok, I posted orginally in the NPM forum (Re: SNMP Events). Since I recently installed UDT as well, we thought it best I posted here.
We have recnetly started getting a lot of %SNMP-3-INPUT_QFULL_ERR: Packet dropped due to input queue full" errors on my big Catalyst switches. This starting happeing around the same time we installed UDT - and is still happening, btw.
I opened a support case with both Cisco and Solarwinds, and have not had much luck in determining if UDT or another Orion product is causing this. Cisco suggested I increase the queue-length on the switch (I did this 2x - first to 100, then to 250 - no change) then requested the MIBs being used by Orion, so i sent that over yetserday. Solarwinds support, provided the mibs, and I am still looking at increasing the buffers more, but I am not sure what other impact this might have.
It just seems odd - has ANYONE see anything like this before? My syslogs have doubled in size since this issue started, and is becomming quite worrysome for me.
Thanks.
