PSOD on IPFIX Enabled SDDCs

Products

• VMware Cloud on AWS

Issue/Introduction

Symptoms:

Host can PSOD with IPFIX enabled (By default IPFIX is disabled).

Cause

• IPFIX has detected an internal port leak
• Port leak could happen when all ports on an IPFIX enabled segment are removed, which could be due to any of the following workflows:

    a) Disable IPFIX entirely
    b) Power off all the VMs
    c) Remove all the VM ports in a segment enabled with IPFIX
    d) vMotion/DRS vMotion
    e) Put ESXi Host in Maintenance mode
 

      Steps to validate if IPFIX is enabled

1.  Under VMC UI, Click on Networking & Security  ---> Tools ---> IPFIX  and validate if there are any Switch IPFIX profiles configured and if they are applied to.If applied to is a number other than zero, IPFIX profiles are in use.
