IBM Universal Manageability Enablement (5770-UME) has been enhanced in V1R4M0 to disable Transport Layer Security version 1.1 (TLSv1.1) protocol connections.
After applying PTF SI77271, a CIM client can only connect to the CIM server using Transport Layer Security version 1.2 (TLSv1.2) or higher protocols. If the CIM client uses TLSv1.1, then the user needs to upgrade the CIM client to support TLSv1.2 or higher protocol connection.
Refer to CIMOM server certificate for additional details.
