Check Text (C-265977r1003587_chk)

From the vSphere Client, go to Hosts and Clusters. Select the ESXi Host >> Configure >> System >> Advanced System Settings. Select the "Net.BMCNetworkEnable" value and verify it is set to "0". or From a PowerCLI command prompt while connected to the ESXi host, run the following command: Get-VMHost | Get-AdvancedSetting -Name Net.BMCNetworkEnable If the "Net.BMCNetworkEnable" setting is not set to "0", this is a finding.
