4 On an individual host, run one of the following commands.

To disable TLS 1.0 and enable both TLS 1.1 and TLS 1.2 on an individual host, run the following
command.
OS Command
Windows
reconfigureEsx vCenterHost -h ESXi_Host_Name -u Administrative_User -p TLSv1.1
TLSv1.2
Linux
./reconfigureEsx vCenterHost -h ESXi_Host_Name -u Administrative_User -p TLSv1.1
TLSv1.2
Note To reconfigure a standalone ESXi host (one that is not part of a vCenter Server system),
use the ESXiHost -h HOST -u ESXi_USER options. For the HOST option, you can specify the
IP address or FQDN of a single ESXi host, or a list of host IP addresses or FQDNs. For example,
to enable both TLS 1.1 and TLS 1.2 on two ESXi hosts:
reconfigureEsx ESXiHost -h 198.51.100.2 198.51.100.3 -u root -p TLSv1.1 TLSv1.2
n
To disable TLS 1.0 and TLS 1.1, and enable only TLS 1.2 on an individual host, run the following
command.
OS Command
Windows
reconfigureEsx vCenterHost -h ESXi_Host_Name -u Administrative_User -p TLSv1.2
Linux
./reconfigureEsx vCenterHost -h ESXi_Host_Name -u Administrative_User -p TLSv1.2
5 Reboot the ESXi host to complete the TLS protocol changes.
Enable or Disable TLS Versions on External Platform
Services Controller Systems
If your environment includes one or more Platform Services Controller systems, you can use the TLS
Configuration utility to change which versions of TLS are supported.
If your environment uses only an embedded Platform Services Controller, you previously completed this
task during the vCenter Server process. See Enable or Disable TLS Versions on vCenter Server
Systems.
Note Proceed with this task only after you confirm that each vCenter Server system is running a
compatible version of TLS.
As part of the process, you can disable TLS 1.0, and enable TLS 1.1 and TLS 1.2. Or, you can disable
TLS 1.0 and TLS 1.1, and enable only TLS 1.2.
