Hi,

No advice and tips, but anyhow...

I've have the same problem (using PI2.2) on various platforms, especially on Cat6k VSS. I've got a TAC-case going but it has not lead anywhere yet. We have tried maximize SNMP Timeout to 60s with no better result.

Regards,

Johan

I've seen this happen on switches that were experiencing persistently high CPU utilization. Generally they will generate a syslog message saying they drop the SNMP requests. Check your switches' syslogs and CPU utilization to see if that's your case.
