Enable or Disable TLS Versions on vCenter Server
Systems
You can use the TLS Configuration utility to enable or disable TLS versions on vCenter Server systems
with an external Platform Services Controller and on vCenter Server systems with an embedded
Platform Services Controller. 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.
Prerequisites
Ensure that the hosts and services that the vCenter Server manages can communicate using a version of
TLS that remains enabled. For products that communicate only using TLS 1.0, connectivity becomes
unavailable.
Procedure
1 Log in to the vCenter Server system with the user name and password for
administrator@vsphere.local, or as another member of the vCenter Single Sign-On Administrators
group who can run scripts.
2 Go to the directory where the script is located.
OS Command
Windows
cd %VMWARE_CIS_HOME%\TlsReconfigurator\VcTlsReconfigurator
Linux
cd /usr/lib/vmware-TlsReconfigurator/VcTlsReconfigurator
3 Run the command, depending on your operating system and on which version of TLS you want to
use.
