We have received a potential workaround from the vendor that has been tested extensively in their lab and confirmed to reduce the CPU utilization on the top-of-rack switches. However, we want to verify the workaround with our own set of tests in the lab first before scheduling the rollout to production. We will provide an update and announce an emergency maintenance once all the tests have passed in our lab as well.
Network Issues: Deployment of Potential Workaround, scheduled 8 months ago
We have tested the potential workaround provided by the vendor in our lab by running multiple test suites and did not notice any negative impact. Therefore, we plan to deploy the workaround in production today (2019-11-12) at 14:00 CET.
In case we encounter any unexpected issues we should be able to roll back the changes in a matter of minutes.
