• Captured packet shows there are no returning SNMP packets.
  
  To capture packets at ESXi uplink, run following command:
  pktcap-uw --uplink vmnic# --capture UplinkSndKernel,UplinkRcvKernel -o /vmfs/volumes/FULL_PATH_TO_DATASTORE/Case_#/esxi.uplink.vmnic#.UplinkSndRcvKernel.pcapng

Environment

Aria Operations for Networks 6.14

Cause

Intermediate network devices (e.g., L2 switches or firewalls) may be dropping SNMP packets, particularly on the return path from the switch to the Collector.
Collector logs may show `No parser found to process` errors if the SNMP response is malformed or incomplete due to the timeout.

Resolution

Contact your physical network administrator to investigate why the physical network is not sending returning SNMP packet to ESXi.
