Hi there,

I am trying to use WoL on vSphere 6.5 and Esxi 6.5. It works, but not stable and take very long time to put a host to standby or exit standby mode.

My physical adapter is: Intel Corporation 82574L Gigabit Network Connection (name vmnic0; actual and configured speed is 1000Mb Full Duplex).

Beside default configurations, I just enabled vMotion (on Networking/VMkernel adapters) so I managed to put my Esxi host in standby mode or exit standby mode. But there are 2 problems:

1. Sometimes I could not put the esxi host in standby mode, it returns “Operation failed: The operation is not supported on the object.”

2. It took 5-10 minutes to put the esxi in standby mode, and took another 5-10 minutes to turn it back on (sometimes it takes forever).

Please tell me if I did something wrong and how to fix this?

Thanks!
