Need Expert advise to understand if  we need to consider down time for  changes to be done on ESX 3.5,Esxi 4.1 and Esxi 5.X
1. Promiscuous Mode     - Now Set to Reject
2. MAC Address Change - Need to set it Reject
3. Forged Transmits        - Need to Set it Reject


Current i have MAC Address Changes and Forged Transmits -With Accept config , so is there any type of Application /OS Environmnet  ..that will be affected due to above changes ?

Or Can we make above changes on Fly.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

All changes can be made to all vSwitches, with no downtime, with no impact to any service.

However, as with all changes to production equipment, I would document what changes you make, and agree before a Change Board meeting, if you follow standard IT Service Procedures, e.g. ITIL.

We would still arrange for any changes to any production equipment to be carried out outside core service hours.

and as ESX 3.5 and 4.1 are out of support and end of life, you have a larger RISK, with those platforms, for service!

Thanks  Andrew ,yes we are following all required processes  to be approved before doing any changes

my only concern is how we will identify before/after change if it affect any running app in my infra  ?

any utility from VMware to check the same ? or if  manual Testing is the only option we have here ?

Testing.

None, it's like changing the physical switch parameters from Auto to Fixed, there is no application, or application that can test this, other than re-test the server.
