Frequent "Delete Distributed Port Group" Task Events in vCenter with Cisco ACI

Products

• VMware vCenter Server 8.0
• VMware vCenter Server

Issue/Introduction

• Why does vCenter frequently populate "Delete Distributed Port Group" task events for a live Distributed Virtual Switch (VDS) when no manual deletions are being performed?
• You notice below events in vcsa using journalctl -b | less command
  • 1568910:<date> 08:51:35 <VC_FQDN> vpxd[33047]: Event [269760981] [1-1] [<date>T08:51:35.747186Z] [vim.event.TaskEvent] [info] [VSPHERE.LOCAL\acivmm] [<dvs_name>] [269760981] [Task: Delete Distributed Port Group]

Cause

• The frequent "Delete Distributed Port Group" tasks are automated lifecycle management actions triggered by the Cisco APIC (ACI) controller via the integration service account (e.g., VSPHERE.LOCAL\acivmm).
• This behavior typically occurs when there is a configuration state mismatch or a "shutdown" status for an Endpoint Group (EPG) gateway within the ACI fabric. When the ACI controller detects that a gateway is shut down, it may continuously attempt to reconcile the network state by sending delete and create requests to vCenter for the associated Port Groups.

Resolution

Please reach out to Cisco Support. This event is initiated by Cisco ACI and must be resolved within the Cisco environment; vCenter is merely logging the requests received from the ACI controller.
