ESX 3.5 Network Security

Hi,

I am about to change the Layer 2 network security on all my hosts to Reject Promiscuios Mode \ MAC Address Changes & Forged Transmits. Can this be completed on the fly or is this a maintenance mode for the hosts job as it may effect VM's connectivity ?

Thanks

You can go-ahead on the fly. It is not required for you to go to Maintenance mode..

Hello,

This can be performed at any time. However be aware that you can override the default vSwitch settings PER port group so your verification/audit steps should include verifying that the settings are still inherited by the portgroups.
