              "serviceDownImmediateAction": "reset",

4. Verify deployment via tmsh

~ # tmsh list auth partition | grep cistest | awk '{print $3}'
cistest1
cistest2
cistest3
cistest4
cistest5

~ # tmsh list ltm virtual /cistest3/app-1/app_svc_vs | grep reset
    service-down-immediate-action reset

5. #1387 duplicated label verification

kubectl apply -f configmap-hub/duplicated-label.yaml

Check from cis pod log, the following logs
